I just got a Stern Meteor. It's been sitting in an un-heated garage for 25 Years. We were told worked when it went in the garage. . .
I checked the test points on the rectifier board and it's producing the proper voltages, however J1 pin 1 is burned and there were two wires missing from J1 and an orange wire jumped to a different point on the board. I repinned J1 and that brought the GI on the playfield back to life.
When I turned on the game it beeped and the red LED on the MPU flashed 6 times and then nothing.
What does the MPU check after the 6th flash?
A few times after cycling the power it flashed 7 times and a few of the score displays lit up with a few numbers on them.
The GI is working but none of the special lights are functioning.
The underside of the playfield has a lot of rust on all the metal parts!
I'm thinking I should replace the rectifier board and repin J1-J3 to get a clean start.
I have a bally solenoid driver board and a lamp driver board and I'm wondering if they would work in this stern machine?
What do you folks think I should do next?
