Trying to chase down a GI problem with my WH20 whereby the GI doesn’t work during a game. It does work in test mode but not as it should. For example, in test mode when it is running the upper playfield GI, the GI under the slings is lit and when the lower playfield GI test is running, no GI is lit.
Looking at the manual, the GI runs in to J120 and J121 (backglass). The pins on the connectors in my backbox though aren’t what is specified in the manual so I’m thinking the person I bought it off has reworked it wrong at some stage.
Can someone with a WH20 please post a photo of their J120 and J121 backbox pinout so I can verify?
PS. I have noticed that several of the fuses are the wrong type (3A instead of 5A) so an easy fix there.
Thanks!
