Dillionsdaddy - sorry for sharing you thread, but since it is common (maybe the same) issue, were are learning some good trouble-shooting steps from Grumpy for us "inexperienced" pinball fixing hobbyists.
Grumpy - I swapped bulbs with a known working bulb at one of the two locations and the bulb still does not work at that location, the one that was there worked at the other location. In Ohming the larger resistor, it appears to be dead. The wires are solid on the board, but the body of the resistor is a "little" loose compared to the others. I'm concluding this is the problem. Do you agree? I'll order enough resistors for all the flasher boards since they are only $1 and since they go bad often, I might as well have them on hand or eventually just replace them all. Attached is a pic of my shopping cart at macrospecialties. Let me know if I am on the right track.
As a side note, I recently just replaced all the bulbs that are not the 89 flashers with LEDs. No one at cointaker, pinballlife, or a couple other websites could tell me which flasher board resistor I needed to cut or do something with to replace the 89s with LEDs. Would I be cutting these resistors, just the smaller warming resistor, or something else for that? Just curious ... as an alternative. Thanks a bunch for the technical help!
