8N LIGHTS FAIL

NO SNOWPLOWING AFTER DARK? 8N 6-Volt headlights and rear work light operate fine on initial power up but gradually dim and fail completely after about 15 - 20 minutes. Mighty inconvenient on a 3/4 mile snow buried driveway at 3:00am in the dark countryside. Had to strap a 9-volt flashlight to the hood to get back to the shed after last night's snowfall. Don't the lights take current from the generator/alternator instead of operating on a steady draw from the battery? What I am I missing here? Any suggestions appreciated - but not in rocket science terms, please. Second clue...yes, I do have to regularly recharge the battery.
Thanks- Bill.

You need to repair your charging system. See the link below..

Bill..... ...simple answer..... .ya' gotts a good battery and a no charging generator.

And yes, your battery dies just about on schedule concerning the electrical load the lights place on it. The electrial load of the ignition system is about 3 amps, the headlights are about 6 amps each for a total of about 21 amps, sucks any battery dry, toot sweet..... .Dell

Dell. I agree with your answer. But a question: On my 2n, my lights seemed to draw a lot of power and would sometimes go out because of a bad ground (I was using the original one wire to each light with the light housing acting as the ground). I later on ran two wires to each light and grounded one wire to the frame. That seemed to cause the lights to draw a lot less power. Am I correct in my conclusion, and if so, why is that ? Thanks O'electrical oracle.

Tim..... ...your observation is contrary to all known electrical laws.

Bad grounds means more resistance in circuit. More resistance means less amps. less amps means less power. All verifiable by "Ohm's Law".

The addition of a dedicated "ground" wire instead of using tractor chassis with questionable metal to metal joints/contacts, will reduce total resistance and thus will pass the full power that the light is designed to operate on.

This means: bad ground, dull lights; good ground, bright lights. ..... Dell

Bill - Dell has got the answer for you, I'm sure. With the headlights starting out bright, then getting dim, it must not be charging. That's gotta be the problem.

Since you're fixing that, I'll mention one more thing you might want to do. In my experience, "N" headlights often don't have a good ground because of rust, dirt, or paint between the headlight bowl and the fender. Inside each of my headlight bowls I have a short piece of 12 gauge wire soldered between the inside of the bowl and the bolt that goes through the fender. It's not visible from the outside and it provides a reliable ground.
