Default 38 Ford 1/2 Ton Burnt Positive Cable

Hello Forum Members

I have no idea why this keeps happening. The Positive Battery cable is getting Fried When I try to start the truck.

Why does this keep happening. It is still 6 volt, all original, all new grounds, rebuilt starter, rebuilt generator.

It is pissing me off.........

Any help would be great

Also has a rebuilt regulator

thanks Jeff

What all have you changed in the charging/starting system? The 1938 and 39 trucks had an adjustable third brush in the generator and not a regulator. As this apparently has been changed, what else is changed.

POS cable (all orig. 6v) is GND. Is it tight at both ends? Is it a larger cable than a 12v cable? Can't use a "weenie" 12v auto parts cable on 6v. DD

Good Morning Fellow Ford Drivers.

I would like to thank (V8Coopman) for the suggestion of getting a larger Positive ground.


Yesterday my mechanic installed the new ""1 Gauge positive battery cable and old Betsy started just like brand new.

thanks Dick for your help.

Jeff

Your old small cable acted like a big resistor it also could have had a bad connection. With your condition the engine was sluggish spinning over and the voltage drop in the cable dropped the voltage to the coil providing a weak spark. Sometimes with this condition the engine starts just as you remove your finger from the starter button. The engine is still turning and the voltage to the coil go's up. The engine doesn't have to spin fast to start remember these engines can be crank started. G.M.
