Hi,
Flashers not working,
the fuse is good

Pull fuse and check with meter ?

Pull bulbs and check with meter ?

Check 20 volt test point on power driver board ?

One of those three.

Quoted from fly:

Check the 20 volt bridge rectifier next.

BR3?? BR4??

BR4.

I had a thought. Are they not working in test ? Or not working in test or in game play ?

If not working in test only, you need to enable the high power interlock on the coin door.

Just swapped out my power board and now mine is doing the same thing. I'm missing the +20v on the board. Going to dig into it today, I'll let you know what I find.

Ok, thanks

Is LED5 lit on the driver board?

If not, check for 18V AC between J102 pins 2 and 3 with the coin door closed (or safety interlock switch closed)

If you don't have AC voltage there, try holding the coindoor interlock switch fully in and measuring again (or watching LED5). If that still does not fix the AC voltage, check the connectors on the cables between the transformer and the driver board J102.

OK. it turns out that I have some connectivity problems between BR4 and the cap C11. the bottom leg closest to the cap pretty much goes to ground right along with the cap. I ran a jumper between the 2 and for good measure, tied all the grounds together in that section of the board. Not exactly where I saw it but doing so gives all that stuff a good common ground and cleans up some power issues.

P.S. not my work, I'm just cleaning up someone mess

fault removed, the broken cable on the switch coin door
Thanks
