Hi all,
I just bought a stern meteor project pin. I can't get it to boot up, but some of the .156 connectors are burnt up and I need to repin them. My question is if the test points are testing to the volts they should test at ( some are a little high), does this mean the board is working correctly? Referring to the rectifier board.

I tested the orange wire from j3 and I'm not getting a reading from that pin. This one goes to the SDU board.

Thanks for any help,

Chris

Thanks for the reply, I only get half the GI lights on, nothing in the back box. The game has a lot of burnt connectors and some shady wire repairs, I'm hoping those are the issue.

When i got it home I hooked everything up making sure all the connectors were in the right spot on the boards, I turned it on and something under the playfield started smoking. Not sure where it came from so I was concerned about the reclifier board.

i dont get any flashes on the mpu.

I took the battery holder off the MPU because they were starting to leak, does that have to be on their for it to boot

The led isn't on at all

What is the Q2? Its a new allteck board that came with it, all the test points are ath the bottom of the board. one is ground, then 5v, then wma, and zero crossing is the last test spot

My test point 1 on the SDU has 5 volts

I'm getting 76 volts there

yes its the original

all the other test points are testing close to what they should be except TP5

ok, sounds good I was planning on starting that tonight, thanks for the help I appreciate it. If that doesn't work where should I look from there?

Chris

ok thank you

I repinned all the connectors to the rectifier boards and I'm getting 0v for tp1, 75v for tp 5 on the SDU. Tp 2 and 4 are testing good. Could there be a problem with th regulator and capacitor on the SDU board?.

The rectifier is testing good, I'm getting 0 on tp 1 on the driver board and 75 on tp 5 on the driver board. I'm not getting 5 volts anywhere except the rectifier board.

The voltage to the driver boards comes from j3? Could it be that connector or the regulator, or capacitor in that circuit?

Can I test the voltage like this without plugging it in to J3?

I haven't re pinned j3 yet, gonna do that tonight. Hope that will be the trick.

I checked pins 10 -12 and I'm getting 5 volts, it must be the driver board

It reads 0

Ok I'll give that a shot, thanks for the help again.

Need help figuring out my high voltages on my rectifier board, test points 1-3 are ranging higher then they should be. I read if the volts range lower its probably the bridge rectifier, what do you need to look at if the volts are higher?

Tp1-6.4dc
Tp2-195dc
Tp 3-16dc

Tp 4-6 are testing within range.

Ok thank you just wanted to make sure, starting to rebuild my sdu board and I wanted to make sure the problem wasn't there. This machine is driving me bonkers
