What is the voltage at the battery post when the engine is at idle?
That voltage is way too low, the alternator isn't charging the battery. The voltage at idle should be no less than 14.2v.
I don't think you need to do anything like that. I would suggest testing alternator output at the alternator post and use the chassis for the ground point. If the alternator output is 14.2v or more, directly at the alternator then you have a wiring/connection issue.
What voltage reading are you getting at the alternator post?
Just a follow up, did you manage to get this sorted?
Good job! That is what I was trying to get to, by testing directly at the alternator. Glad you got it sorted though.
All the best and thank you for using JA!
