I just don't want to go blowing possible good parts. If it's not too much trouble, I would appreciate it. If it is, I'll roll the dice...My wife returned with the digital camera today also so I can take pix if necessary.
FrizzleFried:
Does this sound right? I did some continuity testing. The connector that includes the L FLIPPER BUTTON pin shows continuity with the left button ground. The R FLIPPER BUTTON pin shows continuity with the right flipper button ground. All is good there...
Now this is where things get weird. I go to the next connector (same side board but above the relay). The R FLIPPER pin shows continuity to ALL lugs on both flipper coils... huh? The L FLIPPER pin shows no continuity to ALL 3 lugs on both flipper coils? Is that right? I'd have assumed I would have found the same scenario as with the buttons?
FrizzleFried:
PBJim...
It worked. There is something wrong, I suspect, with my MPU.
Is there any negatives of keeping this hacked for now? Should it be top of concern to get the issue with the relay figured out? I just have it alligator clipped for now, though I'll likely make it more permanent if there's no negative (other than the flippers can be flipped when game over)...
...but wait, I am guessing that TILT will not work properly with this hack, right?
EDIT: BTW Jim, thank you. I appreciate the help.

In a home environment there shouldn't be an issue. The only reason the relay is there is so kids couldn't pound away on the flippers without putting money in. That would wear them out pretty quick of course.

I've not tried yet, but I'd also assume that the relay turns off the flippers during "TILT", right?
If so, does the rest of the switches turn off during tilt? Meaning if the flippers DO work, and I whacked the ball up in to the playfield during TILT, will all the bumpers/switches/targets etc still work (which would be bad)?
I suppose it's not that big a deal being I KNOW I am cheating if I do that...
Also...what kind of voltage is going through those alligator clip leads? I'd prefer to simply leave them as is, but if recommended, I'd solder up something more permanent.
Now to repair the one flipper that was blown when I bought the machine. I noticed that the end of stroke switch was broken. When I pulled the coil off the plastic sheathing was all melted inside preventing the metal "poll" from sliding in and out freely. My hypothesis: The end of stroke switch broke...causing that flipper to over heat thereby melting the plastic insert...
