T1 coil not firing
 

The 2 others are good. I tried another T1 coil but it still doesn't fire. There's power to connector.

Anyone has an idea?

So you checked power, how about ground?

Tried checking for ground, without success. Tried on all 3 connectors, key on/key off...

Oh I just remember that the ground is another wire, it's not on each of the connectors. I'll check the wire with a multimeter. Where should I bolt it? It actually is plugged just below the T1 coil.

if I remembered correctly, there's a ground wire thats bolt onto the "rack" that bolt onto the engine. Check ground and make sure it has good contact.

Checked ground, 0.06 ohm, which I think is great. Now I'm really lost.

Thanks for your help!

Checked "continuity" on both wires, seems fine... If my problem was the igniter, T2 wouldn't work too?

I had an idea. Can I cut the T1 connector and solder the wires with T2?

Here's a way to test your coils:

Check to see if they are indeed within specs. Let me find out how to test the igniter.

I tested my coils, they're all fine. (also tried connecting T1 connector on T2 coil and it won't fire, but if I connect T2 connector on T1 coil, it works).

igniter testing
 

Here's how you do it, however since you dont have the SST, I would double check the voltage to make sure. IF the voltage is there, then I would say you probably have a bad igniter not firing correctly even though voltage present.

See if any FD owners are near you, ask them to swap a good known igniter and see if that fixes the problem. That's probably the most efficient way to do so.

Trailing Side

Insert positive voltmeter lead into brown (front rotor trailing) or gray (rear rotor trailing) lead of SST adapter harness and verify meter shows battery voltage.
Press tester switch 2 to ON and verify that voltmeter needle moves.
Leading Side

Insert positive voltmeter lead into black lead of SST adapter harness and verify meter shows battery voltage.
Press tester switch 2 to ON and verify that voltmeter needle moves.
Replace igniter if it fails any of these tests.

So by swapping the wiring harness from T2 into T1, it fires. But from T1 to T2, it wont correct? If so, I bet money on the igniter being bad. (after checking the continuity between T1 connector to igniter harness)

If I understand the diagram, I should check continuity between brown wire and one of the wire of T1 connector? There's voltage in the connector, I tested it with a test light.

BTW nearest FD owner is at 250 miles.

Your help is really appreciated!

Offer the guy(or gal) and keg of beer + a meal...I'd accept that...check the FS section for one.

Yes, check the continuity at the brown wire from the igniter side, and then at the connector at the T1 coil side.

If the continuity is good, then your igniter is bad. It's a pleasure to help others. However, remember one thing. Help others when you can and that's all I am asking in return ^___^
