My buddy got his bracket for the battlefield fixed and it's throwing the mtr/switch error. With the motor pulled it only turns on for a split second in motor test.
When I ground the tip 102's the motor spins all day each direction. The pre-driver's test ok.
I was going to start barking up the ls374 but got paranoid this is expected behavior since it's not seeing activity on the opto's. The opto's seem ok.
Should the motor spin freely in motor test when not hooked in? Thanks for your time!
We are in a hurry for a party tonight, so I am just going to swap another driver board in and see if it fixes it. Current plan is to probe the ls374 during test and see what it's doing.
