Well, been searching around for a couple of hours now (sodlering some cracked points, 2 loose cables ont he 100 points relays and minor stuff) and maybe found a culprit to the short, i found a spacer that laid across two contacts on the second main plug in the backbox (where the cable from the cab plugs into) and well.... now the 15A 24Volt fuse blows right when i hit the ON/OFF switch instead of the 15A 6Volt when i hit the left flipper button, which is...progress, i guess.
According to the manual that one is for the "Bridge Rectifier":
"IF, HOWEVER, THE 15AMP 24 VOLT FUSE ON THE MECHANISM PANEL OPENS, IT COULD BE DUE TO A FAULTY RECTIFIER."
Have the Rectifier been fried now or do i have some more serious short somewhere? Seriously i have no goddamn clue anymore what is going on, ive checked every damn connection, cable, contact and metal part in the backbox + those "open air" GI metal wire the lamps are soldered on, and nowhere is anything contacting now AFAIK.
Geez naturally it had get a electrical problem of all problems to get, my biggest weakness, right after i get it cheap. *throws hands up in the air*
Now, do i dare put a 16A SB fuse in that place (only ones i got home atm) or should i wait on further experiments until i get 15A fuses?
