Disclaimer: I'm an old EM guy and not familiar with this specific machine, just going by what I can see in the pics. YMMV.
Quoted from Russo121:Pull it all out, rewire as standard then see what happens. Should be much easier to diagnose at that point.
I agree with this for the most part, but it would be nice to know what was going on first.
First, the capacitors are not in series, they're in parallel, at least with each other. Maybe they wanted extra filtering because they're using a 12 volt relay on 10 volts of power supply, by going from the +5 to the -5 and floating the ground.
Is it possible they were trying to use normally closed contacts to do a normally open function? Is it the original start button? Did it have a set of normally closed contacts they could use if the normally open failed?
Other things that concern me: What are the blue and brown wires that exit to the right of the second picture? More hack. And the two power wires that are fed around the sides of the molex connector in pic 1...they need to go. That aluminum is too sharp and pins have too much vibration for that crap.
And please give that little relay a decent burial. It's had a hard life.
HTh's. Best of luck.
