What have I done this time?
Posted: Sat Aug 29, 2015 2:03 pm
Many moons ago I replaced my wiring loom and had it checked out by an auto electrician. He adjusted the wiring so that I could run an alternator.
The car has been running fine ever since and all of the electrics are working fine - However - I was worried about the battery life and put a volt meter between the battery cable (by the solenoid) and earth and found that the alternator is providing a negative voltage.
I reversed the wiring on the gauge and it produces 12.5 volts
What on Earth have I done (pun intended)
Any clues would be gratefully appreciated as am clueless on electrics.
Many thanks in advance
