Re: Light Switch no longer working as designed

Adding even more problems is the fact that a lot of reproduction stuff is no where near the quality of the original Ford OEM parts. Some are better than others so it pays to get opinions from those...

Re: coil overheating

A stand alone coil will be 1.5-Ohms on the primary for operating on 6-volts. It can be used on 12-volts if a 1.3 to 1.5-Ohm ballast resistor is utilized. As mentioned, a 3-Ohm primary is generally...

Re: Flashing Generator

I'm not sure the ammeter knows the difference. It indicates both output and charge rate since they are related. Now if the bus wire is disconnected, the ammeter should indicate that during the...

Re: What kind of frame do I have

Model A vehicles (not to include AA trucks) all use the same basic design frame with many subtle changes over the years of production. They were measured by wheel base so they don't generally pay...

Re: Who does block porting work?

Flatheads will wake up with a good supercharger even if a person doesn't port or polish all that much. Most folks that coax what little is to be had from a port job are looking for better results...

Re: 1940 radio

The two issues to consider are power parameters and whether to use a mono speaker or go stereo. FMs are 12-volt negative ground for the most part. Going mono will allow for a single speaker. Stereo...

Re: Generator light coming on

The warning light indicates that the control unit is not allowing the generator on line. Residual magnetism in the field poles is enough to generate the current to close the cut out pole contractors...

Re: 55 TBird not charging

Yes, they are both regulated or at least you hope they are. It takes better equipment to test the current regulator and properly adjust it and the voltage output. A volt meter only tells part of the...

Re: Generator light coming on

The brushes may be worn down. The spring tension drops off as the brushes wear. Generators don't like high rpm. They tend to put out less the higher the rpm gets and worn brushes don't help much

Re: Bent frame--how bad is it?

A nice big I-beam, chains, one or more hydraulic jacks, or other items such as wood blocks or other metal members can be used to straighten frames. It's been done this way since Christ was a...

Re: Help with 24" wheel identification

Those apear to fit a specific type of hub similar to knock off types. Dayton is one of the few surviving manufacturers of knock offs but I have no idea where those were made.

Re: 55 TBird not charging

Light bulbs are made for specific voltages. If the system voltage goes too far above that, the bulbs tend to burn out pretty quick. A good meter tells all a tech needs to know.

The modern...

Re: Parasitic Drain?

On most alternators 50 miliamps is considered normal leakage. Anything above 80 miliamps in too much.

I quit using the 6-volt conversion alternators due to the high charging level of the voltage...

Re: Bent frame--how bad is it?

When a frame bends, the inside angle is compressed and the outside angle may be stretched. I would say that both application of pressure and heat to shrink can be used to affect the movement needed....

Re: 55 TBird not charging

Re: 3-brush gen problems

While is is feasible, it certainly not currently an easy task to convert an OEM fan type generator. They worked for many years with a cut out. Since output is relativly low, one of the modern diodes...

Re: Information/Opinion wanted on a specific Model A

Re: 55 TBird not charging

Most electric shops would check the battery condition first since that is an easy check. Check all connections between the generator and the regulator for condition and security. Check the generator...

Re: engine swap

There is only about 25 lbs difference in weight depending on how the FE is set up. The problem may be in finding a bell housing. These old cars aren't getting any newer. The Borg Warner narrow 4-bolt...

Re: 3-brush gen problems

Re: Parasitic Drain?

A 6-volt lead/acid battery will have a higher voltage reading right after a full charge but will lose a tenth of a volt after it sets a while. This is normal from my experience.

The newer the...
