Greetings, I need to know if your machine is a C series, F series, or G series, the 753 was made in all three of those versions. Serial number would help
Thanks. Have you checked that fuse #6 (PWM) actually has power on it with ignition on?
Ok, if fuse 6 has power, the next thing you would need to check would be remove the right panel and check the light green/red wire at the push button that activates the aux hydraulics and see if that wire has power with ignition on, not certain about this but engine may need to be running to test that, can't recall for sure.
No worries. If that light green/red wire has power, push the button and see if it has power on the output side of the push button switch. That should be a momentary switch so it would only show power on the output terminal when you're holding the button pushed in.
I understand, that's why you need to check if that switch has power on the output terminal as it not only sends a voltage signal back to the aux controller but also sends power to those two LED lights, from there the LED lights get ground inside the aux control module. If that switch is sending power out of the switch on the output terminal then you either have a problem with your wiring going back to the aux control module or you likely have a faulty module
Let's hope that's what the problem is, but that's the next thing we need to check
Sorry, been a long day for me, just now checking in. Yes, fuse block is located in the engine compartment to the right of the oil filter. See attached diagram.
There should be two orange wires on the C412 connector at the auxiliary module, diagram shows orange wire on A terminal to be power from fuse 6, the other orange wire is the output from the module to the pushbutton switch in the cab. Be sure and check that black wire at C412 connector, the diagram shows that's the ground for the module and it's showing going to frame, not to harness, make sure that black wire is making a good ground.
See attached diagram
RNG is Orange on Bobcat diagrams
I'm pretty busy at work during the day, but I'll try and log in if I get a chance.
I'm thinking yes, if not you likely have a faulty controller.
BTW, on that model machine, C or F series, which your machine is, that model was bad about cracking the weld of the pin boss on the loader frame where the tilt cylinder attaches to the loader frame. Keep an eye on that.
By The Way
Text language. Like IIRC, If I Recall Correctly, or IMHO, In My Humble Opinion, allows one to express a common phrase using only a few letters in text
LoL, well, we're never to old to learn and I'm pushing 62
Another long day for me, just now sitting down to my computer. Awesome news, good to hear you got it sorted out and didn't have to call a Bobcat tech. Cheers
You're welcome, it was my pleasure
