I am guessing that someone else has tried this.
I have a stock alternator in my race car for now (upgrading to new 1-wire later). Relay board and entire harness is gone. I know that I need the external voltage regulator, so I decided I better figure out how to wire it up... It turns out that the plug from the Alt that goes to the relay board is exactly the same connector & pinout of the Voltage Regulator! So it can just plug right in... not so fast. For the alternator to startup/charge, it needs the voltage that is fed from the Alt light in the combo gauge. SO, can I just wire in a bulb from +12V and splice it into the D+ lead on that connector where it goes into the VR plug? Then the system should work exactly as before....?? Is the stock Alt bulb a special wattage? Stu |
