Hi guys. Im looking at a greyhound skill crane for a guy. Id like a second opinion to make sure ive diagnosed this correctly.
THis is an older greyhound, its all steel!!!
It has the 3 board setup in it ( logic, main relay board, claw board)
When i got to looking at it the claw did not grab and it would not go left.
I pulled and reseated all connections in the machine.
Now the claw closes properly but it still wont go left.
I checked +5, its at 5.25 I checked +12, its at like +14(seems high doesent it?)
I have checked the left micro on the joystick, it checks good with a ohm meter. I also powered it on and checked +5 at the switch, i have +5 untill the switch is acuated, so the switch is working and i know i have a good connection from the pcbs to the left switch.
The claw goes right just fine, and its a 2 wire motor correct? So the wiring between the pcbs and the left/right claw motor is assumed good.
I vote pcb issues... What do you think?
