All, Researching a new issue, and note that I have failed to update the resolution on my issue. Intermittent issue came to a head when I jumped in one day, turned the key, and the vehicle had no power. Using schematic and voltmeter, I traced the issue to be between the main fuse block (under...

I am doing some research on a similar problem. I note that this post is several years old. Did you have resolution? My sequence of failure: (2001 Limited 4wd) -charge light comes on. Batt is only a year old, and alt is factory original, so no brainer...replace alt. - 2 months later, light...

Update: Have been on vacation all week. Today was '4Runner day'. Diagnosis to this point has narrowed problem down to the wire running between fuse block and ignition switch. Today, I pulled the fuse block apart. Holy Crap!!! I can't see how you guys navigate that mess of wires with any...

Thanks to both of you for helping out with this. This is becoming a weekend project with the short daylight days, and long work days. I will test as you both have recommended, and report back results. Thanks again guys!

Rain let up enough for me to get back out there. Used test light. Got a good ground. Tested probe in the power socked of interior fuse block. Lit up. Using same ground, introduce probe through insulation of white wire feeding the ignition switch. Probe did not light up. Move it around and...

The rain has returned, and has run be back in. I have the trim pieces removed to get back to the ignition switch. I went out earlier and purchased a test light, so I can perform the tests as requested (seemed like a handy thing to have in the tool box anyway). Do I need to be concerned about...

Thanks again! I will continue reading on my side as well. At least I'm learning more about something that I usually consider my weakness :-)

Additional update: Following this line of questions, I began to wonder about the transmission in park / ignition switch relationship. I used the transmission lock bypass, and moved the tranny into neutral. symptoms still prevail, but what I did notice was that upon returning to Park, the...

Sorry about that, I misunderstood what we were trying to accomplish. Also pulled the voltage across the socket for the 40a am1. I had voltage there, but only 10.16 vdc. Normal? I did not see how to test the circuit with fuse in place. I pulled fuse and inserted multimeter probes into the...

OK, rain has let up here, and I took the multimeter out to check fuses. 10a gauge fuse - Passed 40a am1 fuse - passed While at the interior fuse block I pulled and tested other fuses as well (now that I'm learning a bit about what they are): 10a ecu-ig fuse - passed 10a ign fuse - passed 30a...

OH!!! Fantastic! I was looking in the underhood fuse block :-)

It is currently raining here, and I don't have a garage. Will check when the rain lets up. I did take a pick of my fuse block and cover earlier, and none of my fuses are id'ed as 10a gauge. I do have several 10a fuses, but none identified as gauge. I do have the 40a am1 fuse. I'll pull it...

Thanks! After searching a bit, and not seeing my issue (but there is a LOT to go through), I tried to post a new thread. It wouldn't let me...on account of me being a noob :-) I did finally find a post where someone had a very similar issue, and I kinda hi-jacked it (it was pretty old, so I...

First thing's first, thank you so much for responding & helping with this. I am a shade tree variety mechanic at best, and my weak spot is definitely electrical. The dome light does work, as do headlights, tail lights, and the 'door ajar' light, etc. Voltage at the terminal lug specified is...

Same problem here I am encountering the same problem with my 2001 4wd (220k miles). Moving the key to the 'on' position does not start the diagnostic check where all of the lights come on in the dash. Moving to 'start' does not engage the starter. No noise whatsoever (no click.click.click...
