Tim, et al,

Check out the following post elsewhere on this forum:- http://www.triumphexp.com/phorum/read.php?3,1287410

Includes a wealth of information and embedded reference material - pictures, drawings, extract from the repair manual, research paper (Tony Rhodes), specs, part number cross references for the electronic module and alternate coil ("coil/transformer thing"winking smiley. Essentially when you break the ignition assembly down into it's component parts the options expand.

Good luck. Rgds, DM

Back when I had my TR7 (1977 to 1980, IIRC) Went through three Opus modules and gave up, converting to the Allison ignition setup you show. No issues after that, so I was happy.

Thanks for all the help guys.

I had the new module installed, it still doesn’t work.

It’s the coil, it’s drawing 280k ohms, so is shot.

Does anyone know of the specific coil that I can install in this unit?

It has 4 small bolts that mounts the hei coil into the assembly.

A 1979 Chevy pick-up truck coil is exact in dimensions, but is missing 2 bolt holes, and has a different wiring connector, close but no cigar.

Any ideas?

Delco D525 (NAPA MPE IC22SB ) is the replacement for the original coil. It is not an exact replacement, and supposedly requires new wires from the module to the coil. I do not know if it has all the mounting holes you are looking for. Full disclosure: I do not have this setup, and have not verified the suitability of the replacement.

Thanks Vance, I was just at Napa today, will go pick up that coil tomorrow if I can.

Hopefully it’s not too difficult to wire in.

Keep your old coil. You might find it easiest to simply swap the wires and/or the connector between the two coils.

Please report back on any issues, fitment, etc. and of course whether or not it gets your wedge running.

I picked up the coil today.

I went for the premium version, as the one you named was not available. It’s larger than the one it’s replacing, but luckily the mounting for the coil has 4 extra wider spaced holes that the new one will bolt into.

I’ll let you know once it’s rewired.

Just after I got home from the parts store, I got a call from one of my British car places, and the found me the exact coil/igniter that was installed on my TR7. It’s used, but they told me they’ve never seen one fail before...lol

I’ll get it as a back-up in case the Frankensteined unit I’m making fails.

Thanks

Here's a NOS one on eBay for $29. Depends on how you feel about eBay, my experience has been mostly positive. So if the heavy duty one does not work out...confused smiley

BTW, the replacement coil does have 4 holes in the bracket. drinking smiley

Cheers,
