So, my Totem has been a very solid and reliable game - when it will actually boot. But getting it to do that isn't always easy.
Symptoms:
- When starting up cold (i.e. first time in a few hours), tilt relay immediately locks on. No 5-second delay, just instant tilt. Nothing else.
- If I leave it in that state for 2-3 minutes, then power cycle it once or twice, it will suddenly decide to engage a totally normal boot - waits 5 seconds, cycles the relays, then normal attract mode. And as long as power is left on, it functions exactly as it should.
- Nearly every time I try tweaking something, it works perfectly ONCE to give me false hope, then goes back to its old habits.
Things already checked:
- Battery removed from CPU, very small amount of damage neutralized, coin cell installed.
- Ground mods performed in backbox.
- Slam switch disabled by jumpering C2.
- Coin switches are not shorting. Tested with coin mechs removed to confirm.
- Brand-new Gulf Pinball power supply installed, with outputs measuring exactly as expected.
Any ideas what to look for next?
