P-10 water leak solved

[Autonut1]

Hey fellows, I finaly found that the water leak was coming from around the water pump shaft. I put on a new water pump and no more leaks.

Now I am having a electrical problem. At firist I thought the generator was not puting out, so I took it in and had it tested and they said that it was good. Let me back up. I failed to mention that when I started the car the battery showed discharge on the ampmeter. When I revved up the engine the needle only moved half way to where it should be to show a normal reading. After driving it around the block a few times the battery would become depleated.

The next thing I did was to polarize the generator by touching the starter lead on the regulater to the armature lead . The ampmeter guage

then registered normal,but only for a few seconds, then went back to showing

discharge.

This is driving me bookers! I would appreciate any suggestions any one

can give me.

I Googled "How to Polarize your Generator " this morning and found a few really good things. The first one had the sentence "Every time you disconnect your Battery you must Polarize your Generator"

Well Duuhhh no wonder these past months I've had a couple of no-start-please-push situations. I didn't realize when I use my Quick Disconnect I have to Re-polarize. Ahhh no wonder the needle just stays in the middle.

These days a person can learn just about anything on YouTube. I found a video that had a technician that demonstrated the procedure in a "hands-on how-to" video. Simple as it would seem I view it and make up a rhyme so that I can remember the correct procedure "Hold the BAT and touch the FLD" O.K. got it I won't mess up.

I get down to the truck and I see a diagram of the housing of the regulator which clearly shows touching the BAT to the ARM, so I go with that and touch the bat and arm figuring quality control back in 51 couldn't be that bad. I start the truck up and give it a little gas, it works!

I decide to maintain a wire attached to the BAT terminal with a capped bullet connector for next time.

I do not know who wrote that but I strongly disagree.

Listen to Don C: He is correct. All you have to do is think about how a generator works and what "polarizing" does. It sets a residual magnetic field into the soft iron cores that the field coils wrap around so that the generator can self-energize. Period. Fini. End of story. No magic here.

Think about it: The cut out relay portion of your voltage regulator disconnects the battery from the generator every time you turn off the engine. Removing a battery cable makes no difference as your generator is already disconnected from the electrical system when the engine is off. You certainly don't need to re-polarize your generator every time you start your car.

You only need to do that under few conditions:

1. You are changing the polarity of the electrical system.

2. You have totally disassembled/reassembled the generator and might have gotten the pole pieces in differently than they came out.

3. You have let the generator sit unused for so long that the magnetism has been lost from the iron. I know that you can go decades without that happening. It might be centuries or millennia for all I know.

Just because you found it on the Internet does not make it true.

I will tell you I have disconnected the battery in my 46 and 48 all winter long and when I hook them back up in the spring they charge as normal.

I have a battery disconnect switch.....use it all the time......does not

affect the charging of the battery or how the gauge works.

Could your gauge be bad, or not hooked up right?

One might suspect a faulty amp. guage, except that the battery does go dead and needs to be charged after driving the car.

I sometimes have used a 12 volt bat. to start the car because it starts hard. If when using a 6 volt battery the car does not start right up it drags the 6 volt right down.

Thanks for your input,

I suppose there are a myriad things that could cause that. Please refresh my memory on what you've done to the electrical system on the car...
