#18 of 48 Headlamps not working properly
Dec 26, 2009 (8:07 am)
I have a 1999 Toyota 4Runner V6 Four Wheel drive with 140000K. While driving at night both headlamps turned off. I replaced the headlamp relay located in the engine bay, checked all the other fuses and unhooked the battery cables then reconnected. Now the headlamps are staying on when I turn the engine off and off when the engine is turned on. Can you please help me figure out what seems to be the issue. Thank you.

After three days of tracing circuits , I finally found the problem for this toyota's voltage problem. Under the hood where the mini fuses are located there was one fuse that was to the interior cabin lights as well as other things. this particular fuse had a led in it that lit when the interior lights were activated. This was the first fuse that I checked but it seemed to be working...ie the light lit when doors were opened. I pulled the fuse and checked for continuity and it ohmed out at no resistance on an ohm meter. later i found that the fuse was blown but the light allowed voltage into that part of the system flowing through the light itself,but the fuse was blown. later, when i put a volt meter on the fuse it was only putting 8 v. into that part of the circuit. When I changed to a new regular fuse without the fancy light built in, all voltage was restored and my multiple electrical problems were fixed. I don't know how this applies to your problem, but if you've got any of those mini-fuses with lights built in... get rid of them.
#21 of 48 Electrical? Dumbfounded on diagnosis
Jan 10, 2010 (12:49 pm)
I have an 88 toyota 4runner. I have tried diagnosing this and I am dumbfounded. Nothing seems to be a common connection. It can happen when I first start it or more often, its as I am driving. On my dash the Battery CHarge light, AT Oil light, and Brake light all flicker on and off and then stay on. I have figured out that when they flash and when they stay on..this is when my altenator is NOT working. When the lights flash off or are off completely...the altenator is working perfectly. All 3..altenator, battery, and starter have checked out to be in working condition...when the dash lights are off. Only difference when the lights flash on is the altenator stops. I checked ground and even cleaned them. I have replaced both the positive and neg battery cables and a new connection from the positive to the fuse box. ANY ideas or suggestions will be VERY appreciated! I cant afford to take it to be diagnosed or I definately would!!

I don't know about the 90 4-runner. But mine was an 00 4-runner and I had a different set of meltdown electrical symptoms. I had pulled and checked all fuses by continuity (-ohm meter check), but there was one 15 amp dome light fuse in the box under the hood that had a little led built right into the fuse that lights when the dome lights were energized. The fuse checked ok by ohm meter but was still blown. The led in the fuse was letting only 8v. into the system and causing all kinds of unrelated electrical problems. Hope your answer is as simple as this.

See post #17 and 23. My problem started with the installation of a new radio just like yours... turned out to be a fuse with a light built into it in the box under the hood.
