Re: Lighting Switch Enclosier

The brake switch has battery voltage at all times. It switches battery to the brake light(s) when the pedal is depressed. The tail light(s) are powered in any of the three lighting positions.

Re: LED Headlights

Different "color temperature" LEDs. 6000K is bluer and brighter, 3000K more closely matches incandescent color. Bluer light reflects back into your eyes more when driving in fog, rain or snow, so...

Re: Rumble Seat Hinges part 2

On my rumble conversion I found #10 clinch nuts instead of #12 D-nuts holding the hinges. I suspect this may have been done to align repo hinges to the original trunk lid, but it's been a while...

Re: Headlight "Load Equalizers"

The cowl lamp conversion kits mount the double contact sockets off-center so the taller bulbs fit behind the lens at an angle. The included reflectors are cut away to allow this. I'm not a fan of...

Re: wiring

Armored wire connects from distributor points to switch, red wire from other side of switch to coil. You should be able to find the disconnect fairly easily by checking continuity along the path.

Re: Question About Inconsistent Horn Performance

The generator produces a higher voltage to charge the battery, so the horn will spin faster and have a slightly higher pitch with the engine running. If the horn is very weak with only battery,...

Re: How difficult would it be to convert this water heater from 12V to 6V?

I stand corrected for my fuzzy thinking: V/2 ~ P/4.

In my defense, (somewhat) axle friction and wind resistance will be reduced, and the motor will spin rather faster than expected.

Re: Keeps blowing fuses alternator problem?

The ammeter is between the generator and battery and measures battery charge or discharge current (either direction). Voltage and power are irrelevant to its reading.

Resistance at the ground...

Re: Keeps blowing fuses alternator problem?

Engine won't start without battery voltage at the coil. You can't crank hard enough to provide it from the alternator.

Tom Endy cites the usual cause of what you describe. Clean your grounded...

Re: How difficult would it be to convert this water heater from 12V to 6V?

Power is proportional to the square of current. Fans will run about 1/2 speed.



5V fans can be had, just be sure they're physically the same size. The heavy dimmer switch will keep the speed...

Re: How difficult would it be to convert this water heater from 12V to 6V?

The LED dimmer switch probably won't handle the fan current. Easiest to run it on 6V with a simple toggle switch. The second item you referenced includes a higher powered dimmer, which you...

Re: where is the most idiot-proof diagram of terminal box wiring?

Perfect drawing, Bob, but I don't recommend connecting anything else to the battery circuit. Accessories should be connected to the generator side, same as lighting, horn and wiper.

Re: 12v from 3 brush Ford generator

Depends on forward voltage drop (Vf) of the particular diode. If you can't find the spec sheet, figure 1 volt drop: 1V x 20A = 20W. Grab onto a lit 20W bulb to find out how much heat sink is...

Re: Accessory fuse panel

To use the original 12 AWG wiring the ammeter should be on a 20A branch circuit serving the battery, with the fuse panel sourced from the generator. The battery normally draws about 1A charge so the...

Re: Headlight Help

Another method places the SB behind the original lens, and as you say the double diffraction "confuses" the beam.

Re: Headlight Help

Those are the 8" to 7" adapters for standard sealed beams. Makes the car look bug-eyed.

Re: Headlight Help

I should add that 12V systems reduce current requirements by half, which doubles generator power capacity. The generator can thus handle the load of 50 CP bulbs without overheating.

Of course, a...

Re: Headlight Help

The brightest bulb Ford authorized for model A was 21/32 CP, A-1116. 32 CP stresses the capacity of the generator, and should be used sparingly. Obviously overuse of 50 CP can shorten the life of...

Re: Signs, back in the day

I was a kid in Oglesby, IL, the street signs were 4x4 concrete obelisks about 4' high. The paint faded and had to be restencilled every year or two. Probably replaced by now.
