Headlight problems

[David Shaw]

Looking for some suggestions to help troubleshoot a headlight issue on my Mahindra 4530. Both headlights and the rear work light both stopped working at the same time. Everything else works. I checked wiring terminals to each light and I'm not getting voltage. I checked all fuses in the fuse block and everything is good. Is there a separate fuse block for the headlights and work light? Any other ideas. Thanks for any help.

Sometimes the switch itself may be the problem- check power going to and from the switch in all positions

If light fuses are good and everything else is working on the tractor I would suspect either 12 volts not getting to the switch or a bad switch. The lights should have 3 15 amp fuses. 1 each for high/low beam and 1 for the work light. I wouldn't think that all three would have blown at the same time. When you checked for 12 volts at the plug did you use the ground at the wiring harness plug ? or go to chasis ground elsewhere? could possibly be a grounding problem in the lighting circuit.

Is it registering on the dash that the lights are coming on?

Funny that the indicator lights are on but that could indicate power at the switch.
Does the headlights and the work lights share the same switch ?

Are there relays inline for the lights, there may be a loose connector ?

Just thinking out loud.

Thanks for the replays on the headlight issue. The owners manual was not much help.
I did check ground in the wiring, not the frame. I'll re-check using the frame.
The headlights and rear work light use different switches, but I haven't checked the switches yet. I'll do that.
Where are the fuses for the headlights? They are not in the fuse block on the left side under the hood. Is there another fuse block?
The indicator light on the dash is not coming on as it should when I turn on the headlight switch.
I'll follow these suggestions and check back. Thanks again.
