1995 YJ Electrical problems
Long time lurker, first time poster. Sorry if this is supposed to go somewhere else, I'm happy to repost in the right place.
Having some electrical problems with my '95 YJ. Driving in this morning, there was a new high-pitched whine from the engine/dash - like an overworked servo, or a muffled buzzer. Consistent, didn't change with RPM, but seemed to get a bit louder as I went. Then she started choking. The lights on the dash dimmed more and more, and the engine choked harder and harder. Voltage slowly dropped. Right when it was about to stall, everything lit up and revved up again, and she drove the rest of the way without incident.
Now, trying to start her up, I get full power - lights, dash, even air. But she won't crank or click, completely unresponsive. A little bit on the low side for voltage, and I get a bit of a spike when I try to turn it over.
Has anyone run into this before? My first guess would be alternator, it's a few years old, but I don't have much experience - it's an educated guess at best. Thanks for helping out a newbie!
A bit of history if it helps - had another elec problem a few weeks ago. One of the battery terminal connectors sheared off, and long story short I went through two sets of coated connectors, several failed jumps, and some engine smoke before fixing it with uncoated connectors. Since then the battery has been running a little high, halfway between center and red on the gauge.
