Well I'm baffled here. I checked all fuses (good!), connections (which I found wrong, but good now), I checked voltages at TPs (good!),etc. I got a new motor, triac driver board and resistor board. When I put it into test mode I only get 7 volts coming out of the molex connector. I measured the voltage from J104-4 and -5 I also get 7 volts, weather in test mode or not. I believe I should get 12v. Can anyone verify this for me.

Also, when I'm not in mars test, I get 7 volts from one of the two wires at the molex connector. Is that right?

Thanks Zaza. However, I got continuity between J102 & J104 as shown above. I have 10V at J102-1 to -4, is that right???

I do have 20V at TP7. Interlock switch and multimeter fine. However, I do have issues with some flashers. Flashers #17, 19, and 21 stay on, but they do flicker during the tests. I never noticed it because the bulbs were burnt out. The remaining flashers work perfect. Also, I did a solenoid test, for some odd reason #10 Diverter Low does not trigger, however, #1 Diverter High works fine.

I tested them following the below link, however, I got in range readings, but I did transistor test with the pin off and the board connected. Is that ok?

Again Zara, thank you so much for chiming in, your input is helping me figure out these issues. I made a small mistake after I did your test and recorded the readings. I do not have a issue with flasher # 17, it works just fine. However......
Your testing is different than what I did, below is a list of what I got doing it your way:
J125-
1: 0.524mV
2: 0.561
3: .442 * left slingshot flasher
4: X
5: .525
6: .419 * left ramp flasher
7: .545
8: .535
9: .530

J126-
1: .522 * Right bank flasher - this is ok!
2: .551
3: .436 * left slingshot flasher
4: .528
5: .423 * left ramp flasher
6: .525
7: .543
8: .542
9: x
10: 1.091
11: 1.091
12: 1.075
13: .966

J127-
1: .523
2: x
3: .533 * low diverter
4: .529
5: .530
6: .522
7: .529
8: .525
9: .522

J123-4: .545 mV *revolving lamp

J128 & J129 have no connectors on them

As for the flashers, I noticed a small drop in voltage (~.125mV) for the "stuck on" than compared to the working flashers. Does this give any indication of what could be wrong?

As for the solenoid diverter low, i will check for loose wiring. But what does low divertor do? When the diverter high solenoid is on, it opens the super charger track and when its off, the divertor closes it self. It feels like its spring loaded.

I have another question in regards to the Triac driver board. My J1-1 Red-white wire splits into two Red-white stripe wires. One wire goes to Power Driver Board J106-5, not J106-3 as manual states. I believe this is a manual error as stated in other forum on this site. However, where is the other red-white splitter wires going? I cant trace it.

I guess I'm going to order transistors and diodes. I'll let you know how I make out when I replace them. As for beacon, i'm still baffled.

Thanks Zaza, I appreciate all your input you have submitted in this forum!

If in game the supercharger is loaded and the ball is kept in the supercharger a number of rounds, the hold is just working fine. Or use supercharger-test. *Yes this works perfect during games! I just didnt hear anything snapping or making a clicking noise during test mode.

OK, my J2 is connected to J104-4 & 5. Which are white wires that have red dashes.
How do I check if my beacon motor is 50 Vac? Its made by Bowman Electrical Products Corp. Model E.

I had to take the motor down, but i got the info. It states 12V, 60 Hz, 3 W on the top of the motor.

I disconnected the transformer, I got 16Vac off of the white-red wires. I think I need to just send the PDB out for repairs to an expert... something is just not right. The front of the board looks good, but who knows whats going on behind it.The pin plays fine and all the TPs are good. Again thanks for your help Zaza! My hat off to you with your pin knowledge!
