P-Pump it....

Won't fix a thing, especially if you keep the box on the side of the engine, which a lot of people do when going p pump.

Mine did a similar, but opposite thing a couple yrs ago. Mine would randomly overcharge, according to the dash anyway. When I'd stop and check it with the meter, while the gage still said overcharging. I ended up having a local auto electric shop convert the alternator to self regulating, it isn't even plugged into the harness anymore. It will still rarely on occasion say its overcharging, but it always checks out right with the meter. I can get the contact info for that shop if you'd like to talk to him?

Sorry....

Just couldn't help myself.

I know how you feel, Gary. My son just bought an '06 Mustang that, according to my local Ford dealer, needs a new PCM, SJB, Engine Harness, Light Harness, and Body Harness. One day it's fine, the next day it's not.

Yeah, understandable. I thought I had a thread about it, but couldn't find it. Iirc, the alternator in these trucks is controlled by the ecm, and with that being the only issue I was having, I opted to spend about $100 on the alternator fix, than buy a new ecm. The name of the shop is Newark Auto Electric, he's a mopar man, really knows his stuff. Remind me tomorrow, I'll get you some pictures of how its setup.

Try swapping the "ASD" relay in the under hood panel, with a like relay that is known function correctly.

Red Sleeper · 10-05-2019, 06:54 AM

I had to search ASD relay. It’s an acronym for Automatic Shut Down. Seems the AC compressor shares the same relay.

Link to what I was reading. Though different from your issue Gary.

GROUND, check your grounds....

I would convert to a self regulating alternator if that is the only issue if it was my ride.
