2N lights.

My 46 2N is still 6V. It starts and runs great. I have not had any trouble with it for years. My problem is how dim and yellow my head lights are. Is there a 6V remedy to this problem without having
to convert to 12 volt ? During this time of year it is very hot during the day and it is very pleasant to ride the country roads at night.

google 6v LED and find some compatible with your sockets

Have you turned up the generator output? ( tip # 20) If you do that, keep an eye on the charge w/o the headlights on to make sure you don't boil the battr.

Remember, on a 2 & 9N, you are the voltage regulator!

Model A owners get around that problem by installing 6v positive ground alternators.

also make sure the lites are well grounded, weak grounds affect electrical problems more than you think

Way back when my 9N was still 6 volt when farming at night I could turn my charging up with a dime turning screw in back of 3 brush generator. See Bruce's tip 20.

The most likely culprit is that the lights are grounded to the sheet metal inside the bulb housing, which is now rusty, creating poor contact. I like to run my ground wire from the bulb directly to the battery ground terminal. It's a relatively easy fix and gives you incredibly bright lights.

You can start with testing the battery -take to a local shop. It must meet specific gravity levels, maintain a full charge under load. What does the AMMETER show when running at idle? Does the 6V wiring have a 1-Wire/3-Brush generator and cutout? Does the generator have a belt tension device to maintain correct fan belt tension? GEN will never charge without belt tension. Next are you sure the lamps are 6V? A 12V Lamp will burn low on 6V. HELP: Industry Standard 6V sealed beam lamps are p/n 4019; 12V are 4419. You can test lamp by connecting directly to your battery. Polarity doesn't matter. Two terminals on lamp, jumper to battery posts. If test shows normal, problem lies elsewhere in wiring. Just because you have a 6V battery does not mean it is wired correctly. Finally, don't subscribe to the myth that switching out to 12V will correct all your wiring issues. Many 12V jobs are done wrong as well. Get your manuals and verify the entire wiring system via VOM set to continuity -eschew a test light. Test wiring without power. OEM wiring manuals will have color coded wires -don't go by colors. All wiring harnesses made today are not the same. Once root cause problem(s)are solved, best investment is to get a battery maintainer FLOAT charger (NOT a trickle charger). The DELTRAN BATTERY TENDER JR. for 6V is a good unit. Keeps battery at a fully charge level when not in use and ready to go when it is. $30 at Wally World.

Could be someone has installed 12V lights. I have seen that happen before.
