Hi Matt,
Those ignition switch units look slightly different, I’ll try to take a pic when I get a chance.
The adjustment I made in the voltage regulator was to the gap in the photo below, kept bending the arm on the left to the right until it would keep voltage up to 14v before switching back...
Thanks to all for your advice…I’m very happy to say that the problem appears to be fixed!
I cleaned the ignition connection, it’s a sealed unit but has a small hole in the back so I used electrical connection cleaner, sprayed it in there a few times until it came out clean.
I then measured...
That is extremely helpful, I know my fuse box looks like it’s had a rough ride, and I’ve never checked the backside. I’m out of town for two weeks but once I’m back I’ll definitely do this and post pics.
Cheers!
I should have also mentioned that I checked the fuel cutoff solenoid and traced ground wire, cleaned and retightened. I also changed the battery terminal connections.
So…my problem persists but I may have pinned down one or two areas to look at, looking for advice.
Last weekend after a transfer and trans oil change I took my FJ out for a drive. It ran perfectly for 100km or so and the 5km from home the same issue happened, the instrument cluster looses power...
Cheers, I’m enjoying it, just trying to get some miles on it now to find the bugs like this one 😉
I’ll check the full cut off solenoid, come to think of it it looked like a poor connection last time I was fiddling with the carb. I’ll check it out.
As a dash gauges go at the same time I’m...
I’m not certain what brand gauges but they are just reproduction if the originals, not digital. I believe the connection is just plugged back in to the harness through the original plug but I’ll double check. Good idea, I’ll get the multimeter out next time it occurs instead of just trying to...
I’ll check it out, not certain it has a fusible link but I’ll check for that. I do disconnect the positive post when I park it up as it gets left sitting…maybe that’s it, I tend to just push it back on and don’t tighten it up, it’s a friction fit only
Hi Guys,
My Saudi spec 1982 FJ40 with a 2F has developed a strange intermittent electrical fault. It mainly occurs when the vehicle is just sitting idling, the engine will stop running and the instrument panel loses power. I can restart the engine and it will run but the idle circuit has no...
Agreed, I got caught out on a road trip along the Southern boarder of Saudi last year im my Toyota Prado…I only have the single tank version and hit 500 Kms between gas station, I was in fumes! Jerry cans will be needed as my 40 gets about 350km per tank.
Amazing, loving the stories and the journey! I’m thinking of a road trip next year to some remote parts of Saudi in my FJ40…I don’t have the confidence you have yet in the vehicle making the journey but I know I’d get parts if it broke down. You’ve got me motivated to go for it!
