1991 Chevy Van V8 Two Wheel Drive Automatic 57000 miles
After driving about an hour the back speakers stopped working. Then the front speakers went. Shortly there after the LED's on the dash dimmed, the battery indicator started flashing and the speedometer changed to 88. I was NOT driving at 88 mph. It took about another hour to get to our destination. We turned off the van for about an hour, we had to use the jump box to start it. It worked fine for about another half hour, when it all started again. Within the next half hour the whole dash was dim and inaccurate. The battery and alternator pass the tests. The van is a conversion that has many electrical devises and headaches. There is a toggle switch that disconnects the battery through a battery isolator, but that seems fine, because being off over night, the van still starts. There also is an additional battery isolator that connects the main battery, 2nd battery, alternator, and ignition.
Where should we start to look for the problem?
have the same problem?
