Sorry to revive this old thread but I'm having issue with my snubber board on Pinbot. My ramp UP coil is acting up on game start and I can hear the relay clicking every time it fires.

My capacitor get super hot and starts to leak within 5 minutes. I replaced the capacitor with same result. What could be wrong for the capacitor to fail like that? Could it be the relay that have failed. It's been replaced in it's life.

About the capacitor, would I have more luck with the 2.2uf/250v than the 100uf/100v?

About that relay, what would be the correct replacement for the original?

Quoted from bobukcat:

Most likely cause of an electrolytic capacitor getting hot and leaking is reverse voltage across it. Are you sure the wires haven't been switched and that the cap is installed in the properly polarity?

Yes I'm positive
