Quoted from Asmig:
Checked for voltage at F101 on the driver board? How does the connector look on the flipper board? Check it for cracked header pins? J802 pins 9 and 8, also I would try a continuity test from those point to the coil.
Strange thing... I’m suspecting a Connector!!!
I’ve been diving in for a few hours a night for a week... measured all voltages, traced wires, tested coils, tested transistors, reflowed solder on many connections that looked great, nothing....
Then today, I plugged everything back in I had taken apart last night, tested the center lug on the coil and it fires! Started a game and all is working again, I’m going to replace the factory power connectors with tirfurcon pins, that’ll fix it!
Thanks to you guys for pointing me in the right direction
