I'm pulling my hair out. I've put new limit switches and diode on the open limit switch of the visor. Both switches register in switch test. When I turn on the game, the visor cycles closed then opens. When it hits the open switch, the game resets. There is no diode between the open limit switch and the white/ vio wire, but there's one on the closed limit switch. I've looked at pics on line and it looks like others don't have a diode either. Is there supposed to be one?

Before I replaced the switches, the visor would cycle open/closed without resetting, but a reset would happen in mid game.

Any ideas?

Or this...
Low +5 volts from the Power Supply board.
A low +5 volts coming from the power supply can often be attributed to the 47 mfd 50 volt capacitor at C8. If this cap fails (opens up), a low +5 volts will result. A low +5 volts can cause your game to reset randomly. Also a bad capacitor at C10 (18,000 mfd 20 volts) can cause a low +5 volts. This cap is the main +5 volt filter cap. To test this cap, turn the game on and put your DMM on AC volts. Put the leads of your meter on the positive and negative leads of the C10 capacitor. If you get more than .5 AC volts, replace this capacitor. Filter caps don't last forever. Expect about 10 years life from them (which means most system 11 games should have their C10 capacitor replaced!). But when in doubt, just replace C10 as it's probably due to be replaced anyway.
