Hi again, everyone! Back in town so have a little update. Recently, if I leave my radio on after turning off the engine, the battery drains quickly. I had my battery checked out and it's fine, my alternator charges it fine as well. Anyway, this happened the other night as I was filling up the gas tank. It was on E, and in the time it took to fill, the battery died. They gave me a jump at the station so it was ok. What I noticed, though, was that when I left the station, the Check Oil lamp was off (when I happened to glance at my dash), but as soon as I gave it gas it glowed faintly, but in direct proportion to the amount of gas I was giving it. I would think this would confirm it's a ground issue, right? (Would that also somehow make it so the radio drains the battery drains so quickly?)

I'm going to reiterate the battery cables again. My daughter's PT Cruiser was killing batteries about every 3-4 months. No warning, it would start fine then the next time she went to start it, no click nothing just completely dead. I finally bought an OEM set of new cables and viola, haven't had that problem in over a year. If nothing else, it's cheap insurance. Not sure if you can get OEM cables for either of the engines for the 1st gens, so you may have to make them yourself or find a shop that can fab new ones using your originals as a template. All this being said, I have yet to take my own advice.
As for the lamp, yes it still sounds like a ground.
