Quoted from drsfmd:There are no switches for power on the bottom of the cabinet. Only that cutoff switch.
ok, if thats a knock off switch, look at it, is the longer blade on top, or bottom?
if its on top, it shud be a NC switch.
ok, thats prob cause a relay is not locking in the up position. or, something is cancelling it.
do a manual coin up with the play field up.
can you see all of the relays latching in the up position?
do any of them fall back down when you release the bar?
Quoted from drsfmd:So... push in the coin mech to activate the reset bar, that coil kicks in and just holds until the reset bar is released?
what coil? and it may need to hold for game play. try holding it up manually, and see if power is restored.
Quoted from drsfmd:I have done through all of the switches on the bank that's reset by the bar, as well as all of the scoring ones. They have all been cleaned, gapped, and tested for continuity.
ok, but do the switches all move correctly if you manually press on the actuating plate? there can be a difference in the travel between power operated, and manually actuated.
Quoted from drsfmd:As I mentioned yesterday, there's a single switch on the reset relay that has continuity in both positions-- clearly that's not right.
So, have you unsoldered one wire and retested the switch? it may be a hold switch? which is accross the coil, and can give weird readings.
Quoted from drsfmd:I don't know where I'm supposed to be looking for the next switch. How do you suggest doing this without a schematic.
Well, thats where the reverse engineering comes in play. Sorry, did not mean that as a joke.
keep plunkin away at it, you will see light!
