Re: Preserving cleaned silvered reflectors

x2. It can also crack and craze with heat, a mess to clean off.

I've found salted white vinegar to be very effective for removing tarnish at room temperature.

The modern aluminized reflectors...

Re: Generator polarizing question

We won't tell those guys that the battery doesn't "control" anything, although it appears to - it's simply a reservoir. But that's somewhat beside the point.

It's good you have a VM to monitor...

Re: Generator polarizing question

High voltage readings with no load are to be expected. Generator should not be run very long this way or it will be damaged. The cutout is a set of contacts between the generator and battery which...

Re: Generator polarizing question

I assume you replaced the field windings with 12V ones. 6V fields will overheat at 12V. The cutout is also basically a 6V relay. I think it still works, at least for a while, but best to replace...

Re: I think it's time to move to an alternator

Stay away from the FP regulator. When (not if) it fails it may take your generator with it. Elegant circuitry, but flawed design. Unlikely it will be revived.

James Peterson claims 15 amp...

Re: I think it's time to move to an alternator

Only regrets should be trouble and expense of replacing battery, bulbs, cutout, coil, and field windings. To say nothing of dealing with horn and wiper motors. Switch to negative ground while...

Re: I think it's time to move to an alternator

True, it's called modulation - dwell time vs total time between cylinders; multiply that fraction by the 6V steady current draw.

But, KISS.

Re: I think it's time to move to an alternator

FSB 11/29 simply moves the ignition coil wire from the battery side of the ammeter to the generator side, at the firewall junction box. The ammeter then reads only current to/from the battery; the...

Re: Analog engine analyzer info needed

I've never looked closely at those things, but i suspect you'll have problems with positive vs negative ground as well a 6 vs 12 volts. Probably better to find an analog multimeter.

Re: I think it's time to move to an alternator

Idle readings are normal because the cutout doesn't cut in until higher revs.

10 A at high speed indicates FSB 11/29 hasn't been applied, and it includes coil current as well as battery charge...

The New Departure bearings are sealed - probably always have been.

Re: Battery not charging

I would guess cutout gone open. Yeah, don't run it long that way.

Re: Carb backfire when release accelerator - Part 2

Checks spark plug polarity.

There are others which just indicate presence of spark.

Re: Barn members in the tornado path

Keith, you're referring to Bridge Creek-Moore in 1999, I assume. That was a nasty one.

Re: New Focused-Beam LED Headlights

A big plus is you could use your old crusty dusty dented reflectors with no worries.

$100 a pair is a bit steep; I also would prefer a calmer color. I've never had a problem with lighting up the...

No change to reflectors.

Re: Third Brush Adjustment

All I was trying to say was that a battery has an equivalent capacitance of a couple of farads, which makes a lovely DC filter.

Re: Third Brush Adjustment

20-20 is the appropriate ammeter; it measures only battery current. -10A is about right for lighting load, +10 is too high to charge battery for very long. You should expect a certain amount of...

This should work well for cowl lights. Be sure to select the color.

Re: Amber light bulb

Yellow bulbs only 12V. You can use 6V LED bulbs though, they come in amber.

Re: Where did Tom Wesenberg post go!

I was afraid it was that damned covid thing. Hope he recovers, would be an immense loss to us all if not.

Re: Third Brush Adjustment

I vote for wrong armature - short nose in a long nose. Third brush is under the gnarl of whatever below the other slot. Ground brush he's trying to move has stranded wire to ground.

Re: Horn repair and worn commutator

Push the horn button and work it back and forth under pressure. The contacts do get dirty.
