After 12 days of operation power problems cropped up. When the ball would hit the slingshots or run down the chute to the flippers the power would cut way back. After a few minutes of low power the power to the playfield died. The lights still light up. The fuses and fuse holders are ok. The switches have been cleaned and adjusted. The solenoids and relays resistance is OK. The stepper unit and rat traps have been cleaned. The score motor works and the reset bank resets. The score reels reset to zero. I have a schematic, voltmeter, and jumper cables with alligator clips. I had to replace the 115 volt hold relay coil and after numerous hours of repair time the new coil is dead. I can activate the single switch on the hold relay manually. I am new to this. It's my first pin.
