The Adjustable Voltage Boost Module by MechMan is a simple device that installs in secconds. The 10" long pigtail plugs in between the alternator plug, and the vehicle's stock alternator harness. The voltage sense wire from the AVBM model is then looped onto the positive battery cable stud on the alternator, and installation is complete! By simply turning the small adjustment screw on the AVBM, the user can easily adjust their alternator's charging votlage anywhere from 13.5 to 19.5 volts. Suitable for use with aftermarket or OEM alternators, compatible with 12V, 14V and 16V batteries.
Part number AVBMOVAL fits most 1996 through 2004 GM AD244, AD237, CS130D, Valeo and Bosch alternators that have a non-PCM controlled 4 pin oval regulator plug on the alternator. If your alternator plug looks like the plug refference picture, and has at least 3 pins in it, this AVBM will be suitable. Please contact a sales associate to determine if this AVBM is comatible with your vehicle.
NOTE: Check with your vehicle's manufcturer to determine safe maximum charging voltage. Operating a vehicle's charging system as higher than safe voltage levels may severely damage the vehicle's battery or electrical systems.
