Hi- I’ve seen other posts asking a similar question but no conclusive answers. Van is running fine- then radio shuts off and all warning lights come on. Shut the van down- no restart. Jump the vehicle, all set, halfway home happens all over again. Car goes into a weird limp mode. I get it home and check voltage = 13.7 with vehicle running. I figure a bad battery. Check voltage = 12.2. Battery is 5 years old so I replace it anyway. Start the car- everything good- I think I got it- nope. Happens again, all warning lights on and engine is surging by itself. I can reset it, but if I hit the start button, it does it again and acts like batter is dead. This time, voltage is 7 volts. Won’t snap back until I leave it disconnected for about 5 minutes. I lifted the main cable to alternator and it didn’t change anything. What would be dragging that system down like that? Scanning codes hopefully tomorrow. Any ideas? I will follow up- thanks in advance

Figured it out. When I pushed on the 4 wire plug on the back, it corrected. Removed alternator and took it for a rebuild ... it was shot. When I pushed on the back, it must have made the brushes make just enough contact.

How many miles are on the van? Was there an oil leak that got on the alternator?

99% of the time when vehicles come in to the shop with all lights on, it's low voltage caused by a faulting alternator. And a large majority the time, it's do to power steering fluid or oil finding its way into said alternator.

If it has the same design as the gen 3 engine, the front spool valve tents to leak after a while and if not caught on time it can damage the alternator.
