Are you saying the joystick doesn’t move forward?or are you saying the joystick moves fwd, but the right side drive motor doesn’t respond?

Look on eBay for isocell. They may test for a fee. They rebuild many bobcat modules.

When my aux hydr controls stopped working, I was convinced I needed the module….but I found one handle harness was connected to the wrong mate under seat, and chewed wires at the module. So my advice is to very carefully inspect all wires first, upper left panel, upper right panel, under seat...

Any handle with a good toggle will work too. I changed mine on the 753 from the original square button handles to the cobra head style. Just keep track of the wires for proper splicing.

Thank you for closure on this. As far as the alternator, chasing shorts has no easy fix. Wiring diagrams help. My last wire issue was caused by mice . Took a week, but I found it.

Use the forum search bar and you will find it…

Mine is an early 753 SN 508611665…not sure what series.

Ujoint coupler btwn engine and hydr pump.

Bobcat still lists some of the 753 computers as available. #4 in pic, but you have to use your SN.

Some pics from my 753 for controller (computer)location and aux hyd module location. The one to the left of the driver seat is The aux hydr module electrical controls. There is an eBay vendor who states they can repair the computer/controller.

743 = good machine! Will get most everything done…no BICS, BOSS,trouble codes, computers, etc! Strong enough engine. Just don’t let it overheat.

Some drift down is acceptable, like an inch per hour. Sticking load check valves or off center spool valve position could cause it too. Usually it’s the lift cylinder seals or in my case I had a cracked lift cylinder piston.
