Hi. Im new at fixing pinballs so excuse my ignorance. I've already fixed a few things, easy things. but this one is starting to get me confused.
when i got the game, 2 of the 4 bumpers didnt work. so i ordered new coils for the 2, disconnected them, and didnt take any pics. so when time came to put them back together, i didnt know what side to put the wires. i guessed, and it didne work.
in an effort to troubleshoot, i inverted the wires on one of the other 2 working bumpers to see if my problem was wiring or something else. (yes that was very very stupid, i realize now). so no my other 2 bumpers quite working as well.
now i know the double wire has to go on the band side of the diode.
now that is connected properly, im still blowing the fuse for it.
so how to i find the problem?
i tested 2 of the diodes (they are accessible from the front) and they are both good. getting continuity one way but not the other
i tested the coils and im getting a reading higher then 4. so they are good as well
im not really sure what else to check. any tips? the machine is road king if that matters.
