I picked up a Lethal Weapon 3 and when you turn it on it starts to boot shows version on the dmd then you can see the f5 fuse blow. I did some looking about how a stuck coil could cause this and found the outhole kicker not freely moving so I cleaned it up and that works fine but still blows the fuse. Any direction I should take to dive in deeper? Thanks!

Does anyone know what molex on the ppb controls the coils? I looked at the manual but must be missing it.

Ok so I figured it out last night. I disconnected the J7 molex and the fuse doesn't blow so that narrows it down to a possible bad coil? Also with that disconnected should I still have the game boot? The display comes up with version and the playfield goes through a cycle then nothing else. This is my first DE game so trying to figure it out. Thanks in advance!

So I have made some progress. I have replaced 3 coils and now the fuse will blow violently but the game will go through and attempt to start. When you press the start button the game resets and then nothing.....

Just an update, I was able to get my hands on a new board for testing. After installing still blows the fuse on the 50v supply. So since I do not see any visual problems with any coils with the power off what am I testing?

Anyone have any other suggestions? Someone I know mentioned the bridge rectifier could be an issue. I took a meter to it but not sure exactly what I should be looking for. Thanks in advance!

Ok I swapped out the bridge rectifier on br2. No change. I unplugged cn2 still blows fuse. I disconnect the j4 connector on the ppb does not blow and the game does not start.

The bridge was suggested to replace as a possible problem. Sorry yes the F5 on the PPB is blowing. I have replaced some of the coils that you mentioned and I will check to make sure the polarity is correct tonight and report back.

ScottSerpa I replaced the coil and it does not blow the fuse. What is happening besides the game not starting the coil energizes when you turn the game on and doesn't release. Is that a function of the ppb?
