2005 Mustang GT. I’m still chasing electrical gremlins and I need some conformation. CEL has never come on.
I fixed the bad grounds and checking connections.
When I first had problems with a stubble under load. I found a stored P0340. I replaced sensor and it ran great for one day. Then stubble under load returned.
Car has been sitting for a couple of weeks because I didn’t have time to work on it.
Today I went out and disconnected all electrical connections to the 5 year old PA Performance alternator and the battery terminals. The alt is still mounted in car because with the E-Force SC it’s a pain to remove. I did the diode test with MM and got a reading of .48 with black lead on pos post of alt, and red on case. When I reversed them, I got a reading of 2.45 I’m guessing there is a bad diode. Will the bad diode cause the stubble under load? Thanks.
I tried a different MM and got the same .48 with black lead on positive post. But got zero, the other way around
