Quoted from KSUWildcatFan:Thanks for the clarification. I think we/I just reversed the orange and blue leads...twice...and smoked both of his coils. Doh. That's a $14 mistake (his original coil was getting HOT--I think some wires were arcing, so no real loss there tbh) I'll hopefully only make once.
The switches on his Meteor (my old Meteor) look absolutely hammered. Is there any option other than spending nearly $80 on a rebuild kit? I think he already bought the coil stops for all 3 flippers, so if I could just replace the plunger assemblies and maybe the switches that would probably be okay for now. I assume Williams switches would still be viewed as superior (per Vid), although I'll have to construct something to replicate the setup for the lower right flipper.
He bought a CPR gold playfield that we're having clearcoated and this will eventually get swapped..but not right away. I'm sure he'd rather go silly with all new *everything* when that happens rather than now, followed by that uncomfortable "do I do this again NOW..?" situation when the swap happens.
The coils shouldn't be damaged by reversed voltages, the coil doesn't care. The diodes however will be damaged if shorted.
