Ford V8 generator- self exciting?

[Darrin Wright]

I thought I may have to look inside the generator to see if it is a 2 or 3 brush type.
But taking the easier option, I connected everything up, bought a new 12V battery, made a phone call to a friend as to how to wire up the ignition (now running a remote coil and lost the wiring instructions).
Engine is now running in the hull, placed a digital multimeter across the 2 terminals on the generator and nothing. No voltage reading.

So will continue to run the engine, it is very quite with an exhaust system fitted with mufflers (as opposed to running straight out the manifolds).
It blows a bit of black smoke, I think this is an over fuelling/tuning issue.

My next question may be, how to tune/adjust the idle evenly on the V8...

Hi


Are all carriers 12 volt?

Glad to hear the engine is running good and quiet. Just out of curiosity how closes is your nearest neighbor? A flathead at full song with open pipes can be an assume sound.

My caution in running a generators with no load is based not on having burned one out but from not having to worry about that when trying to get regulator and generator to produce power.

Keep us posted.

Australian BGC were 6V. The engine that I found is a BGC engine retro fitted to a 1951 Ford truck.
I think the electrics were upgraded to 12V at some point as the starter will not turn on 6V under load, but turns freely on 12V.
During recovery I forgot to get the regulator and other minor electrical items.

My neighbour is about 80m away, they have not been too friendly of late, so a little bit of music within the EPA timeline for making noise was not unjustified.
It was sweet music, better that a 6V53 GM out of the manifolds...

In 1951 Ford started using Luca 6 volt electrics.
Ford did make some 12 volt vehicles but very very rare untill the change to 12 volts in 1956.
If your starter and gene are Lucas they will have the model a date and 6 or 12 volts samped on the case.
The Lucas starter will interchange with the FOrd even though the drive is different.
The Lucas and the Ford 8BA gene were attatched to the mounting bracket with a band.the brackets are differenr becausec of the diamater of the case. you can use the single pulley 21A gene or one of the double pullry genies insrtead.
The Ford 2 brush genies can be modified to 12 V by using the case and field coils from an early falcon or late 62 or 63 truck . there is no need to change the armateur.
If the starter is 6V and wont crank on 6 volts make shure that the ends of the field case and end plate are clean and thaT THE END PLATE IS NOT DISTORTED due to over tightening the through bolts.Also check that the brush wires are making goodelectrical contact with the end plate.

John, the wartime 6 volt Lucas geny can easily be converted to 12 volt because the field coils are the only things that need changing. The 6 volt armature works for 12 volt. The 6 and 12 volt cases will inter change as they are exactly the same dimensions.
Darrin, the Ford 3 brush geny will have a cut out (round thing) mounted on top of it.
The 2 brush geny has a separate regulator (it also has a cut out in it)

One obvious thing is to upgrade the 6V regulator to a 12V one when you do this conversion.

My carrier was converted to a 12 volts starter before I acquired it. I then had to convert the rest as I prefer the way it spins over on 12v. I had the help of an old guy Andy, who worked for Joe Lucas for most of his life. I have the standard 6v dynamo with no conversion and a 12 volt regulator and coil. I changed all the bulbs and Andy made resistors for the gauges. However I've never had the fuel gauge working? My system charges perfectly.

I note also that lots of guys who convert their Jeeps to 12v. Do so by still using the original dynamo and starter. I'm told that the shear size of these components will stand up to it?
