Charging Sys Wiring Diagram Question

[tut69]

Diagram F-9 shows the ground wire for #2 gen going to the 12 volt harness block. is this correct? I have a charging issue after replacing the wiring harness. (had a fire caused by a faulty NAPA AR 135)

Thx Michael
I have 27 volts with the engine running from engine ground to Gen 2 positive post and 14.4 from ground to Gen 1 pos post. Is that correct? Thx, Tim

Sounds about perfect.

Actually, 27 - 14.4 = 12.6. That looks a little low to me. I like to measure across each battery. I like to see about 14 volts with the truck running.
