Thanks for your help/ simplification lol

Quoted from GRUMPY:Remove this connector 1J-17 from the CPU board. Turn the game on and retest the power supply.
[quoted image]
OK, without 1J17
1= 0
2= -14.35
3= 14.4
4= 0
5= no pin
6= 14.4
7 to 15 =0
Quoted from GRUMPY:Reconnect 1J-17 that you removed from the CPU board. Now disconnect 3J-5 from the power supply and retest.
[quoted image]
Connected 1j17,
3J-5 disconnected, getting the same results as before.
Quoted from DreB:getting the same results as before.
One last thing to try. Disconnect 11J-3 from the sound board and retest the power supply.

Same results again.

Quoted from dozer1:Power supply needs attention?
Most definite.
Quoted from DreB:Same results again.
On the power supply there is one IC chip. Measure DC voltage on pins 10 and 12. For example I showed you a 16 pin chip, doesn't matter how big or small the chip is the pins are always counted the same. Counter clockwise from the notch.

So mine is a 14 pin chip and 10 has like 0.33 and 12 has 0.
3J6 is still disconnected, should it be reconnected for this?
Quoted from GRUMPY:Are you capable of replacing parts on the power supply?
Yes sir. That's not an issue. I work in telecom so I'm not completely useless. Lol

Should I get a capacitors kit?
Quoted from DreB:Should I get a capacitors kit?
Yes, and a bridge rectifier and 2 diodes.

Mr Grumpy, can I pick your brain for a sec. My Fire is working great except for an issue that happened before the power supply problem. After playing a game, the game stays idol with the regular taunts but the right ramp stays up and I can hear it clicking and trying to bring it back down. Almost like it's stuck in the up position, what could cause that?
Quoted from GRUMPY:Each fix will get easier with experience.
Yeah. Good thing there's this place and people who give pointers
Quoted from chad:Good to hear you have it working now.
Yes, until the next issue haha. It's part of the charm.
