Recently my Earthshaker started resetting. I thought it was the 5 volt section of the power supply. I bought the cap kit to recap the power supply. Before I recapped it I wanted to have some baseline readings to do a before and after comparison; see attached for before voltage readings.

It looks to me like the 12 volt is more of the culprit. Should I go ahead and recap the power supply board, will that fix the 12 volt, or is there something else I need to look at?

Thank you very much for suggestion to look at BR1. I pulled up the bridge testing procedure on Pinwiki and found one of the legs of the bridge was completely dead! I replaced the bridge, put the board back in, and tested the game. I played a couple quick test games; no resets. I also logged my after voltages as seen below.

I'm going to go ahead and replace the caps as you suggested for good preventative maintenace.

Thanks again!

I think as long as it's above 10v it's not at risk of resetting. My friend and I played it quite a bit tonight, after we replaced the caps, and it didn't reset once.
