Voltage to coil on 39 Ford

Don't over think it.... So your 6 volt. if you have a decent re-builder in the area yes. If not then no. Have you checked everything like grounds or battery? Starters typically don't go bad that often. Look at the simple things. The starter grounds to the engine, pull the starter and clean the surfaces and add a ground to the motor first. Or at least pull it and bench run it.

You can also get a rebuilt correct coil for your engine from skip.

Being this whole thread has changed from one person asking a question to an entirely different person asking questions... what is your engine condition, have you done a compression check?

Now new info never heard it run. Try another starter. My guess the bearing are to tight.
May have to tow it to get it started.
 
Tinker....I have pulled the starter twice and checked all grounds and even added a ground from starter case to frame of car. I also bench tested it and it spun nicely without a load.
As far as engine condition, The engine is not bound up in any way as I am able to turn it over easily with plugs pulled out using a wrench on the crank nut.
I cannot do a compression test as the engine will not start.
My brother is the actual owner of the car and he did tow it to see if it would start when he had it at his house. He could not start the car so we assumed the fuel system was the problem. Had the car towed to my house and I changed everything in the fuel system and electrical system, also distributor rebuild and carb rebuild.
The only thing I have not done is rebuild the starter...so that is next.
 
Check the armature of the starter for any signs of it rubbing against the fields...that means its worn in the bushings.
Next are all the springs good...if they don´t put enough force on the brushes you loose power.
 
You say in post 57 you oiled the cylinders so now you may have oil on on the plugs ,I would wash the plugs in gas and poor a 1/4 cup of gas down each plug to wash the oil down ,leave it to evaporate for a hour or two ,then tow it before you deal with the starter .If you are trying a 12 volt battery make sure the ground is direct to the starter ,if you have bad grounds you will draw current of the coil ,




Flatheadmurre I run a beetle battery in my 34 ,no problems is all about grounds in 6volt ,

Not sure what battery you are running...just make sure you have enough CCA rating.
Trying to start a flathead with one of them small 6v battery´s for beetles ends up barely turning the engine over.

On a sunny day a smaller battery works just fine but on a cold day or high compression motor you need amps !
I run my -54 pickup until the snow says no more and on a cold day you find out the difference between a good and a bad battery.
And it´s not about ground...it´s about avoiding losses between battery and starter...goes for both feed and ground side.
 
I don,t like those battery terminals that have the 2 bolts, best cut off 1" and clean good.
I wonder if this was rebuilt and has never run? Bearing to tight will do this slow turns.
For the start of the season I dump some gas down carb few times and I fires up.
Cold weather always push clutch In to limit drag. I would buy another starter.

You don't need to have a running engine to check compression, just turning over. It would be really bad to actually do it running, only two or three revolutions are needed. But you need a starter that can actually get the motor to turn over a couple times. Which sounds like you don't.

My flatheads "seem" like the starter is just barely turning the motor, but it always fires up on the first or second round.

Compression checks are best done with all plugs removed and the carb butterflys open, which will make the motor turn over real easy. Reason for pulling all plugs is to check for any cross compression loss.

Best of luck.
 
Everyone might want to read post #55. zoegrant states that he connected a 12v battery directly to the starter and it still turned over very slowly. We are jumping off in every direction on tangents when it would appear to be the starter that is the issue and needs to be corrected before anything else. If it is not the starter then zoegrant is not checking it correctly with the 12v battery, but it sounds like he did.
