Yep caravans don't like bad battery's or connections
First thing I would do is clean every ground you can find and buy a new battery.
Disconnecting the battery will clear the codes.
Get the battery and charging system right then go from there
And when you smoke your computer from a shiddy battery or alternator you get a rebuilt computer with a few solder joints fixed and maybe a resistor or diode change...an even bigger joke. They never seem to charge right after that. A GOOD battery is the cheapest insurance.
I show that until I got a check eng. & gage light while driving and the whole dash goes dead, then it starts to run like crap and dies with a totally dead battery. Batt was dead but load tests good after a charge, so what's killing the batt with a healthy charging system??? Just sitting in the garage earlier Idling all I got was a MAP code, no "loss of batt. voltage" code and I had every accessory running just to put a strain on it. Did I not run it long enough or what? I ran it a good 20 minutes.Pretty simple to test the voltage across the battery terminals with the engine running. Should be at least 14 volts
Yeah,troubleshooting is a process. You can guess at stuff and start replacing parts. Sometimes you get lucky and sometimes it gets really expensive.I show that until I got a check eng. & gage light while driving and the whole dash goes dead, then it starts to run like crap and dies with a totally dead battery.
