Stranded in Pittsburgh, Code 41

Alternator field not switching! I had Napa send off the ECU for a refurrb because I got stranded in Beckley 2 weeks ago. I am trying to get back Home to Atlanta.

Got the ECU back, because that was the solution the dealer recomended and I had no other choices, but it is still doing it. Voltmeter inside stays around 9 but was at around 14 briefly after the ECU was replaced. Put a new battery in just in case, cause the old one ran dead in Beckly. Voltmeter at the battery says 12.47 when of and drops to 12, then 11.9 when running and lights are on. Dash meter stays at 9.

Man I have to get home. Help Me.

Alternator tested fine. 1994 4.0 Standard

Install a external regulator... like from a Dodge truck.

now it tested fine. But did you happen to check the voltage at the back of it while running? you know just for shits and giggles.

Didnt test from the back while running, will do.

I did just run it down to my budies shop (used to live here) and the dash meter read just under 14v the whole way, about 10 miles. Was reading around 9 when I drove it earlier today. WTF

Maybe it wants to go home too?

Yeah, If you saw the pics and texts my girl was sending, youd be ready to roll too. 239K on it with zero problems so far, guess I was due.
