Help! Another T-Rex issue.
I have been reading up op T-Rex Left-Right issues and have yet to find an answer for my issues.
So I got this game the T-Rex was rigged up to stay in the middle. Wire and zip ties. Yeah I know sound crazy instead of just turning it off and unplugging the cables this is how someone decided to fix it.
After initial testing there was no power to the motor. I fixed this by replacing some bad components on the driver board, couple transistor and a chip where bad.
Now I have power to the motor and can make the head move in test mode just it moves very slow left and right.
Things I have done so far..
Tested motor as good with a 9-volt battery, it moves both ways no problem, will move the T-Rex head very good like this as well so gears and stuff should be ok.
I can ground the driving transistor at the power driver board and the head moves just fine both ways as well.
I have tested the relay board and the shaker motor board in another JP machine. Both work great.
I am kind of stuck at this point, not really sure what to check next.
Any help would be greatly appreciated.
