Anyone have an idea why I would get reset issues when I first turn the machine on and press both flippers. But then it stops happening once the machine has been on a few minutes? Should I be checking the connectors? I already replaced the bridge rectifier and filter cap.

Do machines really need to "Warm Up?"

The jumpers are there, the board was professionally repaired, so I tend to think the problem lay elsewhere. I am thinking flipper coils or diodes next. Possibly the dmd controller board. But it is weird that as soon as it has been running for a few mins, the resets stop.

It was replaced with the rectifier.

I think you are on to something, one of the flipper coils is the wrong size... I wonder.

Only happens cold. If I shut it down after playing, I turn it back on and the issue isn't there. Only after the game has been off a while.

Thanks fusion and ltg.

Wow Wally, thanks. That is some great information. My creature has had a lot of work done to it over the years and it looks like at some point the transformer was replaced. The weather has become colder, so that could have something to do with it. It is about 10 degrees F colder in the basement, and that might be enough to trigger it. I am still going to fix that coil though. It has been bugging me.

I really miss Clay's guide being online.

Kudos to pinwiki for picking up the slack.

Wow, that is a lot of jumpers.

I checked the thermistor, no dice.

I am going to order a new molex connector for J101. It is loose, probably should have replaced that right from the beginning. I am going to replace the flipper coils too, Creature ships with an orange and a blue, but mine has a red and a brown paper (currently held together with electrical tape).

Update to finish off the thread:

The breaker box that my machines are on still uses the old style circular fuses. The fuse blew not long after this thread was started and I replaced it. Have not had a reset issue since.
