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.

Re: Borg Warner overdrive question
The firewall relay powers the system up when the key is turned on. The system uses the governor ground to complete the circuit at the moment it reaches on speed. The downshift switch under the gas...

Re: Disc brakes for wide-5 drums
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!
This alteration has been done a fair amount for folks that want an overdrive with a top shift. The Tremec T170 RTS-TOD has now been out of production since 1987 and they really only had a three year...

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.
