753 auxiliary hydraulics

[Miller Contracting]

Hello all, I have a 753 bobcat with the rectangular headlights. Nothing happens when I push the auxiliary button for the hydraulics. No lights, no noise. I have never used them and they have not worked since I bought the machine. Any advice would be greatly appreciated. Thank you

Not sure but would check fuses and relays.......might have not been activated from new

I just had to do some work in my 863. I'd start out checking the voltage to the coils on top of the control valve. They are 10volt coils and you should be able to meter the voltage on each wire as you select back and forth on the switch. I believe my wires were green and red.

Voltage to coils is good. There is no voltage to the button with the two lights though. Saw no relay for the aux hydraulics

Call the dealer I think I have heard that this needs to be turned on

I'll check my wiring diagram when I get home and see where it gets its power. Granted it's for my 863 but may be fairly close or get u started looking in the right direction. What year of machine is it.

Don't need to attach at the moment but I will in the near future and yes it is bugging me too. I have been fixing up this machine little by little since I bought it and I'm getting really close to having a really nice simple (lol) machine (no computers).So back to the problem at hand I found some female connectors under the cabjust sitting there (5-6) and called bobcat to run through this wiring harness. They said everything sounded fine with all the test I ran. Well I didn't know that there was a control box mounted to the frame until I stood on my head and saw the corner of it. Previous owner must have disconnected them along with some of the safeties. Plugged them in and we are off to the races. Oh and I took the aux button apart and the 2 little lights are corroded off so new switch will be ordered. I really appreciate all the help from you guys. These things are awesome to work on (lol).
