Quoted from tiltmonster:
So when you entered the Single Switch test - T3 - #78 and then ran your finger over the switch it registered the switch (with sound)? If you did not run this specific test please do and let us know if it worked.
Also, if it worked for a few launches then I doubt it's a fuse, they don't work that way, either they are good or they are bad, no in between.
I suppose loose wires, bad connections on the coil or elsewhere may cause it to fail from time to time...
A more detailed picture of the entire coil and switch would be helpful.
As for your Mars Lamp, if the beacon motor twitches, that seems to indicate, if I correctly understand what you're saying, that the motor is frozen or just burnt out. These can be purchased here and it's a fairly easy thing to replace.
It could potentially be that little Triac driver board is bad and they can also be purchase here
Obviously that's a good chunk of change to spend if it's not needed so if it were me, before I spent any money I would do several tests:
Make sure the fuse on the Triac board is good.
Make sure all connections are solid.
Make sure the lamp cover is connected properly to the beacon motor.
I would take off the beacon motor to see if I could manually spin the rod and hear the gears spin.
I'm not sure how you can really test if the motor is working
You should get yourself a Multimeter, it will be very useful when owning a machine, they can test for many functions that you may need to know in the future... voltage, current, and resistance
I'm starting to think the lamp has been an issue for a while, and I just didn't notice it. I'm not too worried about it right now, as I don't NEED it to play.
I'm also starting to think this is just something I can't fix on my own. Unfortunately my pinball "guy" is out of state, and I have no idea when he'll be back. Oh well.
I did the test as you suggested, tiltmonster, and it did register the switch, and made a beep sound, I assume that's what you were talking about. I went through and did everything I did this afternoon in order to try to figure out what caused it to (briefly) work. No luck.
I'll look into a multimeter, altho my thought right now is that I can't even diagnose where this problem is coming from, so I wouldn't have any idea what to do with the multimeter.
I'm attaching a few more wide-out shots of the coil/plunger just in case one of you eagle-eyes' see something I don't. Thanks for all the assistance, guys!
