| In order to not miss anything, ZRD put all of this valuable information on one contiguous web page. Ensure you view everything until reaching page bottom - take your time. | It is important to present a lot of information in one place in order to see the OVERALL BIG PICTURE, how items relate to each other, and not miss something important that may apply to your specific situation or needs. First, High Output Second (dual) Alternators are discussed, then High Output Mounting Brackets, Engine Attachment, Start Battery, Single and/or Dual Alternator Charging Solutions, External Regulators, and Special Products like Digital Duo Charge (DDC) and Centerfielder. Do not forget to view the link for DC Generators from the home page or you may click here. |
| ZRD designed and manufactured solutions fit almost every engine / vessel / installation combination possible. The ZRD design does not restrict its installation to only one engine manufacturer or a few as some others do due to the limited nature of their design. Also, it is not restricted to a limited small subset of their available models. There are no restrictions with ZRD designed and manufactured solutions - If you have the room, ZRD solutions are the preferred design. If you do not have the room, regardless of manufacturer, you will probably not be able to install a high output second alternator. There are numerous products to cover many varied scenarios, especially dual alternator installations. Please email or contact us if you do not see the exact product (if you already know what you need) you are looking for. Our technical team will assist you in selecting the proper solution to fit your needs. We are constantly adding products to our listing. Whether your engine is a Bukh, Caterpillar, Chrysler, Crusader, Cummins, Detroit Diesel, Farymann, Flagship, GMC, Greymarine, Hawk Marine, Hino, Indmar, Isuzu, John Deere, Kubota, Lehman (Ford or Sabre), Lugger, MAN, Mercedes, Mercruiser, Mitsubishi, MTU, Nanni, OMC, Pathfinder, Perkins, Pleasurecraft, Sisu, Universal, Volvo, Westerbeke, Yanmar, or any other, we have an alternator solution for you. |

Pictured above, are a few of the High Output Alternators ZRD manufactures and retails. All of the alternators are mounted in ZRD manufactured mounting bracketry. Starting on the left, is a ZRD manufactured ZCCJE1222 (High Output 12vdc, 220amp) Alternator. Next, is the ZBDJI1216 Spare, Back Up, High Output Alternator that is Internally Regulated and produces up to 190 amps. The last alternator is a Balmar Series 98 that requires a dedicated, special, extremely robust bracket and dedicated adjustment arm due to the higher loads imparted on the engine. All of the other High Output Alternators may use the ZRD manufactured heavy duty bracket allowing for the attachment of a dual 4" foot (marine industry J180 mount) High Output Alternator to the engine of your choice. With a second ZRD High Output Alternator installed, a source of DC power is assured (see link on DC Charging Philosophy). Above is an output curve for a ZCCJE1222. Note: Bottom scale is alternator rpm, not engine rpm. Most alternator/engine ratios are higher than 2 to 1. Divide the alternator rpm shown above by a value between 2.5 to 2.0 to estimate your engine's equivalent rpm. A customer specific output graph is done for EVERY purchase and installation to ensure both engine and alternator proper matching, loading, and output. |

The photo on the left shows a customer's ZRD ZCCJE1222 High Output Alternator's output that he happened to capture (and forward to ZRD) on his cell phone one morning. On that particular day, he said that the output reached in excess of 248 amps, but he was not able to get his camera ready until much later. The instrument doing the measurement was a Xantrex Link 1000 that is known for its accuracy. You may notice that the charge light is off showing that the output is from the alternator and not the battery charger - not to mention, no standard battery charger on the market is capable of producing in excess of 155 amps. Also, there are two yellow lights on showing that the battery bank is discharged, but not completely. We instruct customers to set their lights so that the yellow lights come on when the battery bank is 40% discharged. The red lights are set to come on at a 50% discharge state. |

Its unmatched output will truly assist your efforts to go GREEN. Longer, more usable battery run time, reduce generator requirement and operation. Green Battery Recharge while under relocation instead of at anchor. ZRD has been specializing in the design and installation of environmentally friendly equipment for years - before it became the 'latest popular thing to do'. |

Pictured at right is a ZRD High Output 220 Amp Alternator installed in a ZRD designed, evolved, and manufactured mounting bracket. It allows for the attachment of
a dual 4" foot alternator to the engine of your choice (marine industry J180 Mount - marine alternator bracket). The middle picture shows a ZRD mounting bracket being
used with a Custom-Tailored, Specialized, ZRD Alternator Pulley installed. The ZRD mounting bracket also serves as the belt tensioning device for the alternator and
another pulley powered mechanism that may be included as part of a multi-functional installed solution. This may include items such as a pump or compressor. Its'
universal design allows it to be attached to any engine. The far right picture is a link to a larger photo showing air being supplied via a 3" duct
fan and flex duct. The air is Externally Sourced fresh air instead of ambient HOT engine room air. When combining the removal of hot engine room air and
sourcing fresh outside air, proper Alternator Cooling will be ensured.
Single 1" and 2" foot and most (low amperage) 3.15" dual foot alternator models, regardless of manufacturer, are designed as replacements for existing engine alternators or are specifically designed for direct engine attachment. They need to be kept at the low amperage level (less than 95 amps) so that the attachment point (foot), water pump, or bearings will not fail. The J180 (dual 4" foot) mount ensures even loading and prevents attachment failures. ZRD's bracket geometry allows for each alternator's unique full movement ensuring proper belt tensioning and provides rigidity in the correct planes to ensure structural reliability. An initial view will show the bracket's concise design, but many hours of research, multiple development, and attention to many details were required to produce the desired functional result. Many subtle required details will become obvious during installation. |

Sometimes, there is a bit of a misunderstanding on this item. The engine attachment is a separate item required for the alternator/bracket assembly
mentioned above. It needs to be custom fit for each installation as every boat is built differently and has a variety of propulsion options. Its'
only purpose is to provide a stable platform that moves with the engine for mounting the bracket assembly. There are a multitude of techniques and we
provide guidance on design for all engines. Normally, it is a simple inexpensive item usually constructed from angle iron (preferred) or tubing.
The pictures at right show a High Output Alternator installed on ZRD bracketry on two different engine manufacturers (top - Yanmar 4JH3, bottom - Westerbeke 63C4) using similar, but specific engine attachment techniques. Engine attachment (stable base support) variations are due to the many engine and vessel configurations. There may be items such as filters, pumps, hoses, or other components that end up as obstructions. We provide assistance to yourself or the installation source by suggesting a variety of methods that may solve your situation. The on-site installation source must make diligent measurements and will be the ultimate authority that makes the final decision. ZRD's continued efforts for improvement has simplified this process to a new ease. Our newest brackets have milled slots standard that allow for a very simple one-time alignment of the ZRD bracket onto the 3" angle iron (platform) during installation. |

For Planning Purposes
If you create a cardboard box (pictures to the right - Top & Bottom), apx. 9" wide, 8" deep, 9" high and place it where the alternator is to be installed, you will determine if you have enough room to install a second high output alternator. Note that the alternator pulley and the crankshaft PTO pulley will overlap vertically in a bow to stern direction. By placing the bottom inside edge of the box directly against the existing engine crankshaft pulley you will be in the correct position for prefit checking. In the picture to the right - top), you will see a properly attached ZRD ZCCJE1222 High Output Alternator (220 amps, 12vdc) installed with a ZRD custom 8-Groove Serpentine PTO Pulley with a box over it with the required dimensions needed. In the picture to the right - bottom), this person has the box slightly too high and already has a 3 sheave (groove) PTO installed instead of a 2 sheave or serpentine pulley. For proper placement, the bottom edge of the box should be on the horizontal plane of the future engine attachment platform (3" angle iron). The actual volume required may be less in any given direction because you are using a rigid 3 dimensional object to check and the completed alternator mounted in the bracket is not solid in all directions. There is some free volume to work with (especially in the outboard top and bottom corner positions), but it is impossible to determine without an onsite check. You may send us a photo to allow us aid in this determination. We will be glad to work with you N/C before anything is purchased. |

The first picture on the right shows one of two 500hp Yanmar diesels installed on a custom 57' motor yacht. They are the main source of all system power and
accessories. Each provides a source of 12vdc, 24vdc, 120vac, and hydraulics. A ZRD bracket is attached below the aft accessory power take off pulley.
The pictures on the center far right shows a Balmar series 98 alternator mounted in a custom dedicated ZRD series 98 only bracket described above. It comes with a custom dedicated series 98 only adjustment arm. The bracket is extremely robust to handle all possible loading. If you look closely, you will see a ZRD custom alternator serpentine pulley that will be matched to the custom serpentine crankshaft PTO pulley shown in the picture on the far right. |

| On the right, are pictures of ZRD High Output Alternators (smaller case size) used in Single (Only) or Dual Alternator (Start and House) Installations. This particular Hitachi / Nippondenso direct replacement comes in two versions. One version is internally regulated and designed as a direct replacement for a Yanmar supplied Hitachi / Nippondenso alternator. The other version is also a direct replacement that has been modified to allow for 3 stage external regulation. Both have 12vdc 94amp output. With this higher output, a smaller vessel with a single alternator charging system (unable to install a second high output alternator charging solution) is provided much needed amperage output. Also, those that do have a two alternator charging solution, this High Output Start Battery Alternator allows a nice, temporary, short term, back-up solution should a rare electrical malfunction occur. |
ZRD 12vdc - 94amp, 24 volt - 50amp, 1", 2", 3.15" mounts, Internal and External Regulation. You may click on the picture above or here to see additional details on these alternators - such as their output curves. For post OEM warranty applications, a 12vdc 120 & 140amp versions are available with a Special Order. |

First Alternator Replacement or Upgrade Sizing Checks
If possible, send us a photo of your actual engine (front view, side view - alternator side, & overhead view), existing alternator (close up of front, side, overhead, rear, mounting foot) with the actual dimensions (A, B, C, D, R, S) shown below. Using the example drawings on the left, measure your alternator dimensions (A, B, C, D) and clearances (R, S). • Dimension "A" is the overall size of the existing alternator from side to side. • Dimension "B" is the overall size of the existing alternator from top to bottom. • Dimension "C" is the overall size of the existing alternator from front to rear. • Dimension "D" is size / type of the mounting foot (1 or 2 inch, or a double foot with 3.15 inches in between them). • Dimension "R" is the free space at the back of the alternator until it "runs into" something on the engine - possibly a heat exchanger. • Dimension "S" is the space between the side of the alternator and the engine. It is when the alternator (without fan belt even on is at its closest point to the engine as the adjustment bolt slides in the adjustment arm to its shortest length. This position may require a belt shorter than your existing belt if your existing belt is too long or stretched out. |
