I researched this forum for help with my problem but none of those ideas are working for me.
The balrog motor just continues to run as soon as the machine is powered up. The Balrog has acted a little flaky in the past, blocking the ramp sometimes when it shouldn’t but it always seem to fix itself till now.
I removed the balrog assembly(top of play field) off the motor’s rotating post so I could observe the action without the balrog banging back and forth. I put the machine in test mode and selected the balrog test function which displays the two switches related to the motor rotation. The motor just runs and rotates and according to the display the switches are working. My guess is the switches are responsible for telling the machine when to run/stop the motor and which direction it should turn. The motor just keeps rotating in one direction, never stops and the switches keep opening and closing as the motor rotates.
I removed the bidirectional relay board and reflowed the solder. No change. I ordered a new relay and had a technician replace the relay and the diode. No change. I disconnected and reconnected all the connectors, even the ribbon cable. I tested continuity on the bidirectional board and all the wires and everything checked out.
The only other step I could take would be to replace the motor mechanism. However it’s $150 and I’m not at all convinced that’s the problem.
Any suggestions. Thanks for reading.
