If any expert on WPC could chime in, that would be greatly appreciated
In a nutshell, I have installed one too many mod on my Indy, which seems to have an effect on 12V power rail (still need to take a measurement though).
This results into the left flipper being excessively weak. If I remove the mod (it's an HD DMD, a derivative of PIN2DMD, higher size), I get back my original flipper power.
Now I could try to fix that through a number of alternative options, but first, I'd like to understand the exact mechanism of failure involved, as I must say I don't quite get it.
Optos are LED. Therefore they have a threshold to turn on, if above it's on, if below it's off. So how in the world could a slightly under voltage on 12V could affect the behaviour of actual power output of the flipper ?
If anyone could chime in, that would be quite appreciated
From there I can determine the best course of action, I can see three options:
- Using an external 12V meanwell PSU
- Replacing the flipper opto boards with alternatives (GLM ? Leaf switches ?)
- Replacing the rectifier and cap on the power board
Thanks and regards
