Blowing solenoid fuse

[darren_ross]

Having a problem with the solenoid fuse blowing on the getaway. There doesn't seem to be a pattern to this. Sometimes after replacing the fuse it will blow in the first game and other times it may take a few hours of playing and then blow. None of the solenoids appear to be stuck on and i can't visibly see a short.
Is this a bridge rectifier problem? If so do i replace both and the capacitor?
A nudge in the right direction would be great guys.

Thanks

Could it be a short which manifests itself when something heats up or vibrates vigorously

I had similar with a coil that seemingly worked & measured ohms ok but once warmed up and firing repetitively blew the fuse (and it's driving transistor). Try testing each coil individually and repetitively.

Thanks. I did test the solenoids in test mode. Probably didn't give them a chance to become warm. I'll have another play with it.
