I just bought a 90 4Runner, 3.0 manual 4x4, and I started having electrical problems. The first sign was it didn't start after a service at Jiffy Lube, after a couple hours we got it started but there was no specific reason why. I drove it for 30 min and went home. I turned it of and started it a coupe times and it looked good. Then I got out and noticed the e-brake light and the clutch override light was on after I removed the key. Since it was new to me I thought this was a 4runner thing so I waited about an hour researched the issue.
I went out and tried to start it again. The indicator lights were still on and when I tried to start it I lost all power. So the next day I decided to get the battery checked. It was dead and while it was charging I checked all the fuses and grounding points. I heard the grounding on the engine could cause some weird problems so I ran a new wire and beefed it up a little. Then I went through the dash and found what seemed to be remnants of three different stereo system installations. After removing that I cleaned up the battery connectors and installed the charged battery. It started up and drove great. When I parked I opened the door and the interior dome lights didn't come on but the warning indicators were off. I switched the dome light to the door setting and bam, the indicator lights and fan blower kicked on. It was like the key was in the ignition in the acc position, but the key was not in at all.
So I think someone spliced off of the acc wire to fix a broken dome light in the past. Or a harness could be spliced somewhere. Does anyone have other ideas? I plan on going through each harness and checking for splices or ties ins to figure this out. Thanks.
