school me on the charging system 6 volt

Unknown

how meny volts from the gen when running ? how meny volts from the reg when running from the recharge wire ? its not charging and need to no as much as possible to figure it out . does the recharge wire go to the starter or negtive cable or to the battery ? how do you polorize the gen I looked this stuff up but got different people saying different things ? thanks

I see that you have '49 six. How many volts you would see when the engine is running depends on the change of the battery. With a fully changed battery the voltage from the generator "A" or "Armature" terminal and the regulator "B" or "Battery" terminal should about 6.5 to 7.5 volts. These are the points I assume you talking about. The wire from the regulator "B" or "Battery" terminal should go to the starter. You are right in that there more then one way to polarize the generator. My 1948 - 1949 Mechanical Procedure Manual and my 1955 Motor's manual says to connect a jumper wire to the starter or battery negative terminal and tap it against generator "A" or "Armature" terminal. My 1952 Hudson Shop Manual says to ground the generator "F" or "Field" terminal and then connect a jumper wire to the starter or battery negative terminal and tap it against generator "A" or "Armature" terminal. In reality both are the same. The 1948 - 1949 Mechanical Procedure Manual and 1955 Motor's manual assume the generator "F" or "Field" terminal is grounded through the regulator and the 1952 Hudson Shop Manual does not assume the generator "F" or "Field" terminal is grounded and grounds it.



To test your generator, with engine running, connect a voltmeter to the generator "A" or "Armature" terminal and then ground the generator "F" or "Field" terminal. The voltage should rise. Do not leave the ground on the generator "F" or "Field" terminal for very long as the generator is running full on. If the voltage does not rise, the generator is bad. If the voltage does rise, the regulator or wiring is bad.

your the man thanks for the info this is what i needed to know

At normal temperatures (around 70F), with most stuff turned off and battery pretty well charged, you should see 7.2v at the ARM terminal of the generator or voltage regulator.

Thanks again i got the car running and on the road today and its charging good now . I have a new set of problems to deal with now.
