can you repair an igniter?

[polarweasel]

So what's inside an igniter? Are they repairable at all if they quit working?

I'm asking out of, uh, idle curiosity. Yeah, that's it. I certainly wouldn't be careless enough to touch the case of the igniter with my positive battery cable, nope, no way...

So yeah, I zapped it this evening and now the truck won't start. Cranks, but doesn't fire. And this just days after I sold the ignitor/coil off my parts truck!

I'm not sure whats on an '84 FJ60, but it may be a sealed unit; which means no, u can't get at the darn thing very easily. The older units, like my '79 FJ40 can be taken apart to reveal a discreat component transistor unit for a reluctance type distributor. Now comes the hard part. Finding propriartory circuit information for the Toyota "ignitor". Stupid name, huh? You may have to build a test bench set up for the trigger input and output pulse measurements. This means that u may have reverse engineer the board, unless one can find said diagrams.

The botton line is find a working unit and swap it out.

I've opened mine up now, and it's actually the same unit as your FJ40 has. It turns out the Haynes manual has a circuit diagram, too. However, I think swapping it out is smarter and definitely quicker. Good thing this isn't my daily driver.

I looked into repairing mine. It looks like a simple sircuit, but id'ing the compents was too hard for me. Didin't know the Haynes had a diagram.

Cruiserparts.net has some used and practically new ones for a decent price--just replace it.

Thanks for the dash pocket, BTW!

Discus: No problem. My snazzy new switch panel looks much better in its place anyway.

As it turns out, my ignitor wasn't bad after all. I'd accidentally pulled a resistor out of my TBI wiring. Put that back, and all was well with the world...

somewhere I saw (read) a BB entry about swapping to a GM based 'igniter' device...
Anyone know where that article is/ have link to it ?

Tnx

that would be a handy one to know...

Sounds like a conversion to a GM 4-wire HEI module. It's a piece of cake to do on older ignitions to use as a controller. I actually plan to do it on the slant 6 in my fiance's Dart at some point.
