Yesterday, my playfield lights FUSE blows after a few games use. The original fuse is a 10A and I replaced with the same and it blew as well. I tightened the fuse clips to ensure good contact. During game play, all lights work normally. The game still works, except the playfield lights are out (due to blown fuse).
Recently, a few things happened which may be contributors: A week ago, the kick-out hole contacts under the playfield were touching its light housing, causing the entire game to restart in mid-game. Very dramatic. This happened a number of times until I figured out the issue and moved the bulb housing out of harms way. Once I did that, the game reset issue stopped completely.
Yesterday, I spent some time cleaning the pop bumpers as they were flickering. I was cleaning the bulb mount with sandpaper and the abrasive stick sold by PBR. I bore down on the light socket a fair bit to take away the oxidation. After cleaning, I started playing and the lights started to go completely off and on a few times, then stopped working completed.
Not sure if any of the above is related to the current problem, however I thought I'd mention. The machine worked perfectly until the pop bumper light socket cleaning mentioned. I don't know how to measure current on the 6a bare wire circuit...only continuity - where do I put the 2nd clip? I was thinking of putting in a new fuse and measuring along the wire path to find the surge source. I've performed a continuity test with a multi-meter along the entire 6A light circuit and there does not appear to be any breaks.
Any suggestions would be much appreciated!
