Anyone have G-LOC Deluxe Motor Driver repair knowledge?
I'm trying to fix one that doesn't move. Looking at the two driver boards, the LED on the "Left" one lights, but the LED on the "Right" one does not. I have swapped the two and the LED lights on the "Left" one in either spot, but the LED does not light on the "Right" one in either spot. I'm taking that to assume the issue is actually with the driver board and not with the wiring to it or the pre-board before it.
Now, I have tried comparing reading on all the transistors and diodes between the two and don't see an issue. The fuse is good and the fan runs on power up. Without a schematic, it's a headache trying to figure out what's supposed to be going on. The operating and service manual has some minor troubleshooting info, but nothing really relevant, and my searching hasn't come up with anything but unanswered similar questions.
Now, I also don't know what affect the side safety optic sensors have when it comes to testing. I have the covers off the cab, so they're not lined up, but I'd assume that the LED would still light even if the software doesn't allow the motor to run - especially considering that one does light.
I'd appreciate any advice you can give me....
