AVBM II for most GM vehicles from 1987 - 1995, including CS130, CS144, CS121 and most othe alternators with a rectangular 4 pin plug.
The AVBM II (adjustable voltage boost module) is a simple, easy to install device that gives the user the ability to adjust the charging voltage of their alternator. A 6" adapter a harness plugs in between the alternator plug and the vehicles original alternator plug. The in-car control module is then mounted inside the vehicle. An easy to read blue LED voltmeter displays the alternator's charging voltage, while a simple adjustment knob mounted on the control module allows for quick and easy voltage adjustment on the fly. The AVBM II is compatible with OEM or aftermarket alternators, as long as the alternator was built with the standard internal voltage regulator for the original vehicle application.
The AVBM II is proudly made in the USA, and is guaranteed against manufacturer's defect for two years from the date of purchase.
NOTES:
It is imperative that the AVBM II is never turned up above the recommended charging voltage for the vehicle, battery, or equipment installed in the vehicle, otherwise serious damage may occur.
