Voltage discrepancies wpc board touch points

[DRD]

My funhouse all seems to work fine, but i tested the voltage at a flipper coil and it troubled me. Tp6 confirmed i have an issue

Does anyone know of a good internet guide to fixing this when you have issues please? Voltage readings from the solenoid board ...

Tp1 is 13.6 versus 12 it should be
Tp2 is 5.0 versus 5 it should be
Tp3 is 11.9 versus 12 it should be

So all fine so far. BUT

Tp6 is 79 versus the 50 it should be

Tp7 is 23.5 versus the 20 it should be
Tp8 is 19.5 versus 18 it should be

Thanks

75v is correct, the manual is misleading you have no issues.

From memory it's something like 75v is required to ensure all the coils are getting 50v under load
