This one has me a bit baffled. Replaced PPB relay, disassembled/cleaned ball launch assembly, and replaced BR1 and C1 on the PPB, but ball is not getting up launch ramp about 50% of the time.
50V line is 71VDC normally, and gets as low as 41VDC when firing launch coil.
I even tried firing the coil directly (grounding drive line) and no improvement.
Also noticed some issues with the 6 ball assy lockout in the trough. Took it apart, cleaned, and lubed metal pivot points but it sometimes doesn't completely actuate the assembly. Much less often than the launch issue, but maybe they are related?
