My 4010 ( + gn, ) GEN light stays on all the time. I have replaced the regulator, the generator bench checks ok, wired per owners manual and polarized. It is a real SOB to start but once its up and running it will go for hours. Next question before I order some books is there some type of pressure regulator in the hyd. system? I have a front loader on the tractor, however the hyd. valve bodies for the front loader keep cracking. Any ideas? Thanx to all who reply. Paul.....

I have a 4010 D, built late in 1961. This same problem happened with my machine, for me both the GEN and the BAT light would come on; the GEN light first. My JD mechanic told me to keep the idle speed at around 1000 RPM. He said that this will be easier on the hydraulic system, and keep the GEN light and BAT light from coming on. This solved my problem.

The hyd pump has a valve in it that regulates hyd stand by pressure. It is adjustable by turning in the screw to increase pressure and out to decrease.I think this screw is on top of pump back plate. Otherwise on the bottom. Hyd standby pressure spec. id 2250 psi but 2300 psi is acceptable.
As for the gen light how do u keep the batt from draining down over night? If this is a gas machine I would check the point gap if not, I would pull the cover off the reg and you may have to readj or tweak the points in the reg itself. Not sure if this will fix but its worth looking at. Good Luck
