Re: Voltage regulator, generator wiring (12 volt)

The early voltage regulators were mounted on rubber bushings so that the buzz of the VR pole wouldn't be detectable. This required a ground of the VR case to the system so they took it directly to...

Re: three brush regulator

The 2-stage unit was a cut out with an extra control relay. The control relay would allow the generator to charge until the battery was fully charged. With the battery charged, the system voltage...

Re: knowing when my car was made

Engines were stamped after they passed the operational test with the big electric motors that turned them. If they passed the amp load check of the big electric motor and there were no leaks then the...

Re: model a engine

Pull the head and see if it has original type valves and standard size pistons. Pull the valve chamber cover and see if it still has solid tappets and two piece guides. Pull the pan and look at a...

Re: Aluminum alloy model T wheels

One way that they could be aluminum would be if the individual spokes were cast from aluminum then assembled like OEM wood spokers would be. The spokes appear to be individual. I also wonder how wood...

Re: knowing when my car was made

With so much water under the bridge, it is near impossible to get an exact day no matter what branch assembly plant may have been involved. Most major assemblies were sent in batches from the Rouge...

Re: Aaaa

Re: 1940 Ford Zenith Radio

A lot of the old radio sets have a diagram inside the case. They are usually pasted to the cover.

Re: '46 Coupe 59AB Starter

The green bible indicates that the 18-11005 armature was used in starters for the early 8BA (7RA). The number was likely changed later in the 8BA era but they are likely interchangeable. The ones for...

Re: Phaeton top rest question

Re: Fuse size

Henry had intelligent people designing his systems but the era that the model Ts and As were manufactured in left a lot to be desired on a safety standpoint. Fuses were not common until the early 30s...

Re: What color are these cars?

Early in the 30s Ford had light maroon and medium maroon. By 1939, they had 3 or 4 different maroons and some darker reds as well. This is from the Auto Color Library....

Re: Fuse size

Rob Doe has it. The fuse is to protect the wire. Each different American wire gauge (stranded AWG) size has a corresponding fuse size to protect it. This link has a chart on page 505 of the PDF...

Re: 1940 Ford Zenith Radio

I'd keep the vibrator if it's still functional. The old sets are a good learning tool about radio sets. They were actually pretty simple but as was mentioned, the caps or capacitors like to pop like...

Re: my project and my thanks...

There is a lot to be said about running these old flivers whether they are restored or just good drivers. They are a lot of fun either way.

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

Re: Henry and Edsel again

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: 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...
