I've been working to bring a TFTC back to life. I'm scratching my head a bit with an issue causing the F5 fuse to blow on PPB. I'll lay out the best I can what I have done thus far.
Checked all coils for ohm, lowest value I got was 2.5 the rest were over 3. 2.5 was on the crypt vuk
narrowed down to what connector is causing the issue and its J3. The connector with all the grounds
Tried checking the transistor but apparently my dmm doesn't want to give me anything. Or every tip36 is bad. It's an Ideal 61-765 and it does not have a diode mode
I wasn't able to determine what direction every diode should be banded. The groups of coils are banded on same side but between the pops and vuks they are different.
I know it is J3 because I only had power and J3 to the board and the fuse blew. I then have every connector hooked and only J3 off and nothing blows.
During my search I also determined that F9 was over fused and somehow missed that during the initial run through. So I suspect that if I hook it up now F9 on PPB may blow instead of F5. I only have so many 5A fuses so I'm using a life line.
List of issues:
right ramp switch does not activate during switch test
Launch switch does not activate during switch test
Upper flipper does not fire but the bottom 2 are strong
crypt vuk does not fire
up kicker does not fire
knocker does not fire
Obviously a lot of this would work if I had J3 plugged in.
I feel as though i am missing something very simple that just hasn't smaked me in the face yet.
Any tips on this one?
