Re: charging
I have digital and analog meters and use both. My Fluke digital was purchased to adjust voltage output on aircraft 24-volt systems so they would charge at 28-volts. The fluke was the most accurate...

Re: What water pumps do I need?
FWI, the 37 through 48 pumps will bolt up to the engine but they only work well when the whole front of the motor is converted to early style. This also requires the early style cam and gearing to...

Re: Looking for a quality 6 Volt Starter
1 gauge or larger cable is what 6-volt systems like for starter motors. Heat related problems can sometimes be an open in an armature winding. They will pass current until it expands from engine heat...

Re: Henry and Edsel again
That delivery certainly had all the bells and whistles. Dual chrome plated horns and dual windshield wipers plus chrome hub covers. That was quite a delivery van.

Re: How many miles should spark plugs last?
How long the electrodes last depends on what they are made from. The resistors are another fail point in plugs so equipped. If you purchase iridium electrode plugs then the resistor will likely be...

Re: Grease in 2-tooth
Some folks use John Deere corn header gearbox grease for it's thixotropic nature. It is fluidic when parts move in it but more of a jell state when parts are at rest. It is a brownish color so that...

Re: How do I test field coils in a starter?
Starter motors are shunt wound with heavier guage wire in order to get a really good torque output. By changing to series wound fields, it just reduces the torque capability. The original fields on...

Re: Ballast resistor for 12V coil
Most 12-volt systems are regulated to 13.5 to 14-volts when the alternator or generator is in function. A 6-volt system should run at around 7.1 to 7.2-Volts.

Re: Ballast resistor for 12V coil
The built in resistor is a misnomer that I see a lot. It just has more resistance in the primary coil. The higher resistance primary makes more heat but modern internal insulation is a specific epoxy...

Re: Borg Warner overdrive question
The rail switch opens the circuit to the ground action of the governor so the main solenoid can't operate electrically. The rail also blocks the pawl so that it can't move mechanically. This is the...

Re: Ballast resistor for 12V coil
A 1.2 to 1.5 Ohm ballast resistor will work for a 1.5 Ohm primary type coil. A person can use a 3 Ohm primary type coil and not need a ballast for 12-volt conversion.

It might not be very practical to do a set up like that for the Ford wide 5. It could be done with adapters but it would change back spacing on the wheels. The adapters would have to clear the...

Re: 37 coupe RTS T-170 swap!

There is a kit available from model A sources to repair for deteriorated horn rod internals. A volt/Ohm meter is the best way to test the horn rod assembly.
