Worked on a supercharger accelerator board for a guy that complained his supercharger was slow. Not sure if these boards were populated by hand or by machine, but if by machine, look at D10 on this board. This board was not repaired or worked on. It was a factory original.

The circuit is very much similar to the Hi-Current Solenoid Drivers on the PDB so I think it works with a resistor (~100 ohm) or with a diode.

The other 2 magnets had diodes in their circuits but this one did not. The SC time test value was 169 with the resistor in the circuit and when changed to a diode was at 95. I compared it to my accelerator board it had diodes in all 3 magnet circuits.

The resistor measured out at 220ohms. It was the same resistor that's between the TIP102 and TIP36C that was placed in the D10 location.

I'm surprised the ball would even make it around the loop @ 169! When mine had issues it bout seemed to struggle in the 140s.

Well found ! The SC with almost twice the speed is much more fun

It was definitely slow. Probably bounced around 155-169 being the highest reading...maybe hit 140 once. It did make it around though.

I've never been more disappointed to discover a PCB in a pin was properly assembled... Congrats to all that this works for, though - great catch schudel5!

I have a sluggish supercharger. I have replaced the super driver accelerator board, and it’s still sluggish. It tests out at about 138, bit the driver board says it’s rated for 85. I have testing meters, just unsure how to test the magnets and what I would be looking for. So if I replace the magnets as well, will that bring it up to speed?

Same issue here. Same board replacement same rating, same result.
The speed also depends on how smooth the ride around the SC is for the ball. The magnets either work or they don't.

I know I’ve seen on mine and another HS2 I worked on that longer screws sometimes are put on the plastics over the supercharger and the ball can hit them. This slows it down too. Check that and make sure its clean and waxed.

You could unplug all the magnets and plug in one and test one at a time with a ball.

Can you make a short video of a single ball in supercharger test mode? That should help share the issue.

I'll share my insight. My supercharger was slow-ish and somehow seemed weak.
After receiving an electric shock from my supercharger ramp when installing a flasher, I measured and found the ramp itself to sit on +72 V.

Reason for this was the diverter coil, which had made contact to the ramp metal.
Fixing this issue did a lot to the game in terms of supercharger speed and general snappiness of the coils.

If you have a slow SC and dont know why, you might want to measure he voltage on the ramp. if it is at +72V, fix that and your SC times should improve.
