Oh btw Jeff,



Did you get the PM I sent a while you awhile back?Wanted to see your progress on the GLC.And yes its techically a REPU now seeing as it is a Rotary Engine Pick UP...

Having two genuine REPUs as I do, I tend to call the previously piston powered trucks like yours and Dan's, rotary B series trucks or rotary B2000s etc, but never REPU. It certainly doesn't take any more effort to roll off the tongue than ARR E PEE YOU.



Besides, my friend had both an '86 rotary B2000 and a '77 REPU. It didn't make much sense to call them both REPU. Rotary trucks they indeed were, but only one could bear the covetted title REPU.



It's REPU envy, but that's ok. I'm flattered that you would call a previously piston powered truck an REPU. In a way, it pays homage to the orginal. It's just a bit confusing when I come across threads in a forum like this one though.



I looked through my PMs but didn't see one from you within the last year or more. I have to swap flywheels soon. It's got a used RB light steel flywheel and a good used 225mm disc and P-plate. The flywheel had a 215mm disc on it so I'm going to install a new flywheel so the 225mm disc can wear evenly. The used flywheel will go into my MG with a 215mm disc. I also have a brand new 225 HD disc and plate from RB, but I think they'll go into my Cosmo with a GSL-SE flywheel (big car, 27 lbs flywheel, HD disc - sounds like a good match to me).

Finally got my new dizzy after purolator screwed up on shipping.$400 later I have it in there and still nothing.
Holy crap! I wouldn't have gone out and bought a new one. Pull-A-Part distributors are $10 if they don't realize there's ignitors on them. I have two spares I keep around.
What else is needed to make spark on these motors?
There's not much else, no ECU or anything funky. If you're not getting spark and you only have 9.3v at the coils you have a power distribution problem.
Hey J9FD3S would a faulty ignition switch cause a 3 volt power loss?My stepdad seems to think that the ignition switch would be the cause... But why would it just lose the voltage all of a sudden?One day good next day nothing.
Ignition switches have multiple contacts, so one circuit may lose power while the rest still work, and yes, bad ignition switches are 'good' one day and 'gone' the next.

I'll post a update tommorow after I track down three more coils seeing as I fried mine by a simple mistake.

UPDATE.. .Next time you lose spark make sure you don't have any grounds other than your ignitors grounded to your coils.

Yep. An FYI for everyone else: Just because the coils have a negative terminal, it doesn't mean they're supposed to be connected to chassis or negative ground. They should only ever be connected to the C terminal of one ignitior each (one ignitor per coil). This is also where the (usually green) signal wire of a tach is to be connected. You'll save yourself a lot of headaches if you remember this small step.
