Can anyone help identify the circuit that these two resistors are in? They let out magic smoke after replacing the 24v slow blow fuse. I believed it was a 5A slow blow.
The joy stick will make the movement sounds in all directions. The fire button sounds while pressing it followed by a countdown sound and finally GAME OVER sound. BUT there is no movement in any direction of the crane.
I applied voltage directly to the motors and they seem to work. I've replaced the cables with no affect. I removed the pcb and I applied voltage to the relays and they seem to respond. I removed the transistors and tested them with an ohm meter and they seem to test fine.
After I replaced them in the board the crane motor did drop on start up which was new. And it then blew the 2.5 amp 24v power supply fuse.
I replaced that fuse with the 5 amp and these two resistors smoked.
I put yet another 2.5 amp fuse in and it did not blow but I'm back to just making sounds and no movement by the joystick
However
When I remove the gantry cable that goes to the claw, the crane suddenly drives to the back of the machine.
Help please
Thank you.
