  • This voltage boost harness fits alternators with a GM 4 pin plug and is similar
  • Plug and Play
  • This harness can be used with engine swap applications where the stock alternator harness is not available
  • NOTE: This unit is NOT FOR USE ON STANDARD 12V AGM BATTERIES. This module will increase the charging voltage by appx. 1.0 Volt and will swell and damage AGM batteries. Please check with your Lithium battery manufacturer to verify the proper charging voltage before installing this module!


This voltage boost harness fits alternators with a GM 4 pin regulator. The 2.5-volt increase has only been tested on the 4 pin regulators used in Mechman Alternators. If your current 4pin equipped Mechman Alternator voltage is warm/resting at 14.6 volts, this harness will net just over 17 volts in the same temperatures. Ambient temperatures will affect output. Warmer environments, less voltage. Colder environments, more voltage. Please ensure your added items such as car audio amplifiers are capable of handling the higher voltage as to not damage them or go into a protect mode. Please ensure you have proper belt grip on your alternator as this will increase resistance and will only make any belt slip you currently have MORE noticeable.



Different brands or lower quality sourced regulators can have less or more voltage change. The yellow wire gets connected to an ignition switched 12V+ source to turn the alternator on and off with ignition and the blue wire with ring terminal gets connected to the alternators threaded output stud. This harness can be used with engine swap applications where the stock alternator harness is not available, and you just need a way to turn the alternator on and off through a 12v switched connection.



This harness may also be used WITHOUT THE BLUE WIRE CONNECTED as previously stated if you are currently running a regular battery but plan to upgrade later to a Lithium battery later in your build.



NOTE: This unit is NOT FOR USE ON STANDARD 12V AGM BATTERIES. This module will increase the charging voltage by 2.5 Volt and WILL DAMAGE 12 VOLT AGM batteries. Please check with your battery manufacturer to verify the proper charging voltage before installing this module! Not all Lithium type chemistries require higher voltage charging!
