Does anyone know the proper ohms spec for the supercharger coils?

I get a reading of 3.5 for all 3 that seems low.

Coils are so weak that the time test is in the 225 range.

In supercharger test they all work only so weak they barely send the ball around once.

Diverter is perfect. Ramp is smooth and clean. Balls are not magnetized etc.

I reworked the optos and opto board including installing a socket and new LM339

Optos test fine in switch test and supercharger test.

Accelerator board transitors were all tested while I reworked the board.

This is a head scratcher for sure thats why I am focusing on the coils. Wires all good and respective connectors all good.

Fuses and all connectors are clean and solid no shorts to be found anywhere.

All the usual suspects have been checked yet the coils remain weak. Any ideas thanks.

as i mentioned on al's fb post, i'd be looking to see if the optos are flaky during operation. even if they test good in switch test, heavy vibration from the diverter and the ball movement could possibly be causing the optos to open and close sporadically, which would cause the current magnet to de-activate before the ball is even past it.

I replaced the optos with new an reworked the opto board just in case there was something there.

I also replaced the Lm339 on that board.

I would have replaced the cap on the board too but didnt have the correct value one in my stock.

i don’t see how the sc driver board could make it perform slower or faster. i’d think each of the 3 circuits either work or they don’t. it seems they work. so the prob most likely lies in the timing of the activation of the magnet coils.

Just replaced all opto pairs on the Super Charger and no change. Must be a board issue will rework the power Driver Board and see if I find anything there.
