Hello Experts - I am not one. Just posting this questions proves I am NOT an expert. I want to know if I can substitute SG-23 850-DC coil in place of the burned up G23 750 DC coil. The first coil is from a Williams Alien Poker that I am parting out. The coil that burned up cuz it got stuck open is in a Williams Grand Prix.

What do you think? Can you educate me on whether this is a good or bad idea please ! Thanks much, Jim

I was cleaning the playfield and flipped one of the rubbers behind the switch and the switch was stuck on. I've replaced the coil, but now none of the bumpers nor the kickers work. Ideas ? I've check the fuses, no luck, all tested fine.

Thanks for all the tips. So, after frying the lower left side sling coil because I had the rubber wrapped around the switch and kept it on, I've been busy learning and repairing. I did use the substitute SG-23 850-DC coil in place of the burned up G23 750 DC coil. On the entire game, only two of the coils have diodes on them. The two slings of course. The alien poker coil had a diode on it as well, good deal. Hooked it up and since I didn't carefully check the direction of the diode..... the God of Hell Fire showed up and huge sparks started flying out of the switches under the sling plastic when the ball hit the switches. Fun !!! I cut off the diode, reversed it and put it back in. Better, but still shooting sparks. So either that diode was no good or just not big enough. I cut the old diode off the burned coil with hopes it survived the original burn up. It did thank goodness, problem solved. Thanks much. BTW, the new coil is just as snappy, maybe even more snappy than the old one. Good deal.
