I have a friend that is working on his JDX4 and his headlight keeps burning out. I have read in the forums that it might be a faulty regulator. His tail light remained lit. Does this seem logical? Also I am not sure if he is even using the right bulb. The John Deere headlight part number is AM52959. Will a Napa H5006 work?
Thanks Maynard.

Re: JDX4 Headlight
Maynard, check the wiring to the headlight for a short. There are lots of pinch points. Yes on H5006.

Re: JDX4 Headlight
Yeah like Matt said, hearing your description, more than likely it's two bare or cut wires touching each other or your power line is grounding out somewhere.

Re: JDX4 Headlight
I am thinking it is a over voltage condition that is the cause of the headlight blowing.
Check the ground on the voltage regulator. Make sure it is secure where it is mounted to the chassis.
A single wire voltage regulator requires a good clean ground connection to operate and also to serve as a heat transfer.
A new regulator is only $20 so if in doubt replace it.
Another thing to consider is vibration. A headlight bulb can burn out prematurely if it is rattling or bouncing around a lot.
Confirm that the retainer clip is hooked at all four corners. Also make sure that the flip up grille is seated tightly when closed.
Maybe one of the springs that hold it down is missing or stretched.
A short or broken wire would be an under voltage situation and not cause the headlight to burn out. It would also cause the taillight and gauge lights to not work or be very dim.
