I'm puzzled. Purchased new stator kit from Rex's Speedshop for my DT360
www.rexs-speedshop.com/product/dual-powe...-b-c-dt360a-12-volt/

Big fat juicy spark all right, but only when the flywheel is spinning in the wrong direction. Any ideas? There's only one way to mount the stator, and all the wring seems to be correct (it is sparking, afterall). I'm hoping someone has run into this before.Or maybe Rex can chime in, as I sometimes see his name on here.

Thanks!

So it’s on a 74 Dt360A correct? I’m not personally familiar with those systems but there are some who are and I’m sure they’ll be along, so ya might have to sit tight for a bit. When you say it’ll spark with the fly wheel going backwards, are you spinning it by the flywheel nut or similar, or is it running backwards when you kickstart it? You might post some pictures of the wire up or better yet, a short video might be best.
I think 75-76 Dt 175s had a diode wired in to keep them from running backwards. They were a points system though. Good luck!

Best to reach out to Rex's and see if they resolve the issue.

I've heard of several issues. Including running backwards. That owner said Rex's told him he needed a different flywheel from a different model I think.

Maybe they added a diode to prevent backwards running and yours got installed wrong or something.

Thanks for the feedback so far.

Haven't been able to start it, as when you kick it over, the fly wheel spins counter-clockwise, so no spark. When I rotate the flywheel clockwise by hand, it sparks.

The flywheel is stamped with the numbers that are required as per Rex's site, so I sure hope that I don't need a different model.

I've sent an email to Rex, so we'll see what he says and will report back...

Happy to hear any thoughts on here, though, from anyone who might have had similar issues with a pick-up less stator.

Cheers,

My random guess is its been accidentally reverse wired from the stator coil. Only saying that because we had a local guy rewinding coils for us at work for many years & wasn't a DT360A but a TT250 that had a Brown & a Red from each end of the stator source coil & was a very similar problem . Phoned him up & he said swap the red & brown & that fixed it--but heaven help the next guy to work on it if he was following colors lol. Better contact Rex's or wait a little bit & should be along. We'll all be interested in the answer.

You don't think this is wrong, correct?
You agree that the flywheel is supposed to spin counter-clockwise, right?

Hi Deet, the flywheel should indeed spin counter clockwise. It just doesn't spark when it does.

This is the response from Marcus Rex. Would love to say it's helpful.

"Hello

Yes that odd. Never seen or heard that before as the unit locks out. This lockout occurs as the conditions cannot be met to fire the SCR that controls the capacitor IE anode more positive than the anode when the fire signal is injected."
