Hi guys, i see that this topic has been covered a few times but it appears as though im experiencing a different problem. My ferris wheel relay doesn't appear to be grounded by the driving transistor. If i ground the relay drv input my wheel spins, so i moved up to the transistor, grounded that and my wheel spins. That led me to the pre driver transistor, Q2 which i also replaced but it appears the center leg is grounded, would this be a problem with U17 thats only effecting the ferris wheel driver and pre driver, or would the rest of the solenoids using u17 be experiencing issues as well?

Thanks for your time!

Yes Q6 was also replaced.

I did try test mode as well. I will double check test points this evening.

Went ahead and replaced u17 because i had spares on order anyways. Ferris wheel then came on 24/7, when back to Q2 as it was shorted even after I replaced it (my guess is u17 caused it to short), swapped it out again and everything appears to be in working order!

first I gotta fix the dang mystery wheel xD
