What's the correct wiring for the coil on a 82 GSR?
The car starts and runs fine but the tacho does not work and was like that when I got the car so I'm hoping there's a wrong wire somewhere.
The way it is now is:
negative terminal (on left):
thick black wire with white stripe
solid black wire which runs to the gold coloured resistor thing
solid light blue wire which runs to the black resistor thing
positive terminal (on right):
solid black wire which runs to the black resistor thing
light blue and off white wire in a single terminal clip
I think the tacho feed should run from the gold resistor box via the off white wire you can see.
Thanks,
Mike.

Thanks for that. Is there an easy way to test the pulses from the off-white output wire with a meter or bulb or something? I guess I could also run a wire from there directly into the dash gauge if I can find the right pin. I hope it's not the gauge that's stuffed since it a digial dash...BLOFLY wrote:This part here acts as an isolator to pass the coil pulses to the tacho display in car. I know that if it's disconnected there is no tach reading. Hope this helps :beer
Cheers,
Mike.

I've just got out the Mirage and hooked the negative coil from that to the off-white wire of the Starion and lo and behold it shows the revs on the Starion guage. This proves that the problem lies in the coil or isolator which narrows it down nicely. I did bypass the isolator by jumping directly from the negative coil to the off-white wire and still nothing showed up. Should this have worked if the coil was good?
Cheers,
Mike.

I'd suspect the isolator but the tach should have worked straight off the coil as you bypassed it. Just be careful running without the isolator as I believe it's there to protect the tacho.
The problem could also lie in your distributor. If it is supplying a poor signal to the coil then it may affect the tacho reading. I'd try swapping coils first as that's pretty easy.

The ignition coil is wired incorrectly.
The Thick Black wire with the white stripe goes to the Coil +.
The Light Blue wire and White wire go to the Coil -.
The thin black and white wire which drives the tacko also goes to the Coil -.
The solid black wire goes to a noise supressor can be thrown out.

Beautiful! That did the trick. Thanks so much for the correct wiring! I've tried all sorts of things short of tracing the wires through the loom but I had a feeling there was a wrong connection somewhere and the fact that the thick black/white wire was connected negative was suspect too. How the car started and ran like that I don't know.
So, for future readers, the wiring should be:
negative terminal:
solid black wire which runs to the gold coloured isolator thing
solid light blue wire which runs to the black resistor thing
light blue and off white wire in a single terminal clip
positive terminal:
thick black wire with white stripe
solid black wire which runs to the black resistor thing
I'd been scouring engine bay photos for the wiring too but none show enough detail. Does anyone want a project to photograph all the parts of the engine bay and post hi-res images for reference?
Cheers,
Mike.
