Tried to start my 1990 YJ 2.5L to night and nothing. No attempt at the starter solenoid. No clicking from starter. No accessories. Low indication on volt meter. Headlights won't even come on. I wait 15 seconds turn the key and it starts normal.
Battery was on the charger today. I made the mistake and started the Jeep with the charger still hooked up.(maybe an issue) It's a modern electronic charger I use to recharge my boats trolling deep cycle batts. Jeep Battery still showing 12.4 volts. The battery is showing it was made in 2007. Maybe that's the problem However, I thought the headlights would at least be on dim if it was just a low batt. When it did start, it cranked normal so the battery had juice. I drove it 5 miles home and I pull in the driveway and turn the key off with the headlights ON and the headlights go dark. Back to everything not working.
Is there a relay that could be stuck 1/2 between start and run and that's why it's showing no power then later starting normal? Like a starter rely maybe? It's weird because when I say dead (nothing) I mean NOTHING is on or working all accessories dead. The LED's on the radio face are barely readable.
Nothing worse then electrical issues.
Any starting points?? Relays to check??
