Quoted from red-line:
Gotcha. It shouldn't be a problem on mine, since I just replaced the coils, and didn't mess with the flippers or assemblies, right?
I sigh every time I read statements like this as the actual flipper coil is the LEAST likely part to fail in the entire flipper assembly. The coil is nothing more than a spool of copper wire, as such it has a specific resistance per foot which mean if it measures correctly then replacing it is pointless as the problem lies elsewhere.
The most common problem is its just dirty, but given the low cost of a flipper repair kit, if you are disassembling this for cleaning you may as well install a flipper rebuild kit. For some reason these kits don't contain the bushing which I also like to replace whenever I have this assembly out of the machine.
The only thing I do that is the same as the OP is I remove the coil stop to pull the coil from the assembly; however, I leave it in place and still soldered to the coil wiring harness. I then remove the EOS switch again leaving it connected to the wiring harness so that I can remove the rest of the flipper assembly from the playfield. These are the parts I actually clean and rebuild using a rebuild kit plus a new bushing.
