Hi, was playing my AFM the other night. Had a good game going, had
multiball, and then something happened. I think I lost the opto's.

Turned it off, turned it back on and got the Check fuses 101 and 109
J127 and opto 12v supply message


I pulled the fuses and checked them, reseated the ribbon connectors,
and reseated the connectors near the transformer.


Today I checked the voltages with the game on at the test points on
the driver board. Here is what came up


100 12.16
101 5.08
102 18.30
103 14.80
104 22.10
105 75.0
106 .415
107 -15.1


Are these about right? What do I check next?


Thanks, in advance!! Brian
 
Check if all leds on the powerboard are on.. don't remember which one is for the 12v, see your manual or pinwiki.com .. maybe a bridge or one of the caps is bad..
 
Yes, all the lights led's on the driver board are lit.

Thanks, Brian
 
I also reseated all of the connectors to the opto board and the led on the opto board is lit.

Thanks, Brian
