Hello to all.
I just purchased a used 1994 JLG 45HA and I have a few questions and things I would like to fix on the machine.
I do have a couple operations moving slower than the rest, so I bought the test harness for the controllers so I can re-calibrate/test them. I put a pressure gauge on, and it builds pressure, but slower than the rest.
One of the questions I have, is for the drive. It is only 2WD, but it seems that the motors are only linked together (hyd with the divider valve) in the forward direction. Has anyone ever looked at adding another divider valve to the reverse line, so both wheels are driving in the reverese? I will be doing quite a bit on grass, and I was hoping the 2WD would be enough for what I am doing, but was disappointed in the reverse driving.
The drive alarm does not work. There appears to be a notor controller for it that is burned up. When I look up the part, it's $580. I can't see spending that kind of money on it, but would like to fix it. Anyone know of a newer modern kit that would work? The alrm does work wit 12V on it. I traced the wires back, and ihave 12V and the FOR and REV feed wires, but I assume they are from the controller, and not 12V feeds, so something needs to monitor those and drive the alarm. Hence the $580 controller.
Also, it has a 120V box at the platform. There is a 120V plug in the engine compartment. Is that just an expensive extendsion cord? It does not have the genererator, but I wish it did.
Instead of the expensive $2K generator, anyone ever add an inverter to the machine? I am possibly looking a doing that sometime, maybe in the spring.
Other than that, it seems to be a good machine. I will be looking into tires possibly. They look like crap, but they are foam filled, so they work.
Thanks for any help. There is a lot of good info on here that I have been reading thru.
