something you should look into: what is the field current draw on your 250Amp alternator and what is the PCM max supported current output on the field control wire
reason i mention this is if you replace your PCM (which is the problem by the looks of it at this point) it might not last if the control field current is over the limit, so in the end an external regulator could be the way to go - just something to consider.
Was thinking the same thing. So right now on fence, but would tend to give the external voltage regulator kit a go.
Saturday, when my second set of bulbs blew and same electrical problems emerged again, I was blacked out. No high beams/no low beams and about 14 miles as the crow flies from my place.
So, I kicked it for 6 hours until the sun rose, expecting to drive it back. 6AM -- Wouldn't turn over. I'm wtf?
Battery is fine. I walk away because I'm pissed thinking about the tow I'm going to have to hire. I get a donut and some coffee, come back in an hour. Try again. It decides to start and I'm giving it gas to get it running. Manage to make it back to my place.
Thing is, got myself into a really first class cluster-4uck in the last 6 months...
Dude in my building, November last year, says: "hey like to use your Jeep in a full-length zombie picture I'm shooting. Pay for the nights using it."
"Ok," I say, thinking it'd be good for some laughs.
So last November went fine, no problems. Dude said he'd start shooting the other scenes in February, this year. Well, this April, dude finally starts wanting to shoot the other scenes.
I say, "Vince (substitute name), Jeep is having electrical problems, lights blew, you can use it for day shots, but nights it's no good until I can figure out the problem...and that could be awhile. He's like: "well I got to have it fixed, I'll pay it." I said, "ok."
Shop says bad alternator, says install new alternator. I want par with what I had before, not shop's oem quote. So I buy a 250 high amp replacement and some bulbs, shop installs them.
"Vince" gets another night shooting last Friday. Then bulbs blow again -- electrical problem still there. Tell him this a couple of days ago. He's like: "oh need it by May 9 working again, will pay for it."
Yeah great -- thing is "Vince" doesn't know what he's getting into. And, yeah, there's some "commerce" here with his production's use of my Jeep, but we're not talking a financed feature here. "Vince" ain't rich - he 4ucking lives where I live...
Have my head on too many things, distracted. Need to go to the drugstore this morning, am not feeling well. Hop in Jeep, get what I need. Come back out to the lot, Jeep won't crank. I'm like -- "jh wtf am I thinking even attempting to drive this thing."
So, stuck in a private drugstore lot -- 30 minute we-tow joint. I sit there for about 90 minutes - nothing. Forced to call for a tow, pay for the tow, tow it to the same shop as before, then $80 to leave it there so they can look at it again...
There's no conclusion on this post. Just beside myself right now.
