JD 5310 no low beam headlights.

I have a 5310 that the low beams will not come on but high beams will. Warning lights are working. Replaced light switch and flasher, cleaned the ground by the battery. All fuses are good. Power leaving the switch. Bulbs have continuity and work on high so believe they are fine. What am I missing?

I know it doesn't seem likely, but isn't there a chance that the low beam filaments are bad in both bulbs? I think I'd eliminate that before I started trying to go farther.

Can you put a voltmeter on the modular plug terminals to verify that there is NO voltage on the LOW BEAM setting? You should see voltage when on the HIGH terminals but not when on the LOW terminals. If there is voltage, I'd replace the bulb.

If this doesn't lead to a resolution, I'd drink a beer and decide whether I really needed the LOW BEAM setting.

Change bulbs

Use voltmeter to see of you have 12 volt on low beam terminal at bulb plug...
