I've been reading Firepower threads for about 1.5 hours now but still not sure of my issue.
Every time I think I have the problem corrected it eventually comes back to haunt me.
Problem is the driver board lamp circuit transistors and power resistors become very very hot.
At the or near the same time fuse F2 for the solenoids blows. I don't know if it blows before or after the parts in the lamp circuit heat up. Parts in the solenoid circuit seem to be cool to warm, but not knowing when the fuse blows, it could have had time to cool off I suppose before I noticed it and machine starts acting crazy.
BTW, it does this while just sitting in attract mode. Never has while playing it that I recall.
I checked most, but not all of the controlled bulbs and they are GE44. I was thinking about replacing them with #47 bulbs, but anyone think that could be the issue?
I plan to recheck all of the solenoid circuits when I can get back to where the machine is, just in case there is a stuck switch or bad solenoid, but looking to see if anyone has any additional ideas as it is a 130 mile drive for me to get there.
I'm also confused as to why the lamp circuit is heating up so bad, or is that the way it is?
Thanks for any ideas.
