Thought I would share this story of a Meteor repair. I have a Meteor that was not booting. The LED would come on but not flash. So I broke out the multimeter and started checking test points. I started with the MPU and found my 12V TPs were only getting 10V. So I moved to the rectifier board and started checking TPs on it. I was getting 10V there also. So I checked TPs E11 and E12. I checked the first one and got 10V. I went to check the second one and sparks flew. As soon as that happened the pin booted up! I checked the TPs at the MPU again and it was at 12V. I was afraid to check it at the rectifier board again. I know I didn't accidentally touch 2 things at once when the sparks flew as I'm always very careful about that. So I don't know what caused the sparks to fly and why that caused the 10V to jump to 12V. But it's been working fine for 3 days now. An easy fix I suspect I'll have problems again in the future but for now I'm happy.

Quoted from zacaj:

You shouldn't be checking E11+12 separately, they're AC. You measure across them.

I guess that explains the sparks . I still wonder what caused the voltage to jump back up.
