Re: [Chrysler300] generator/charging issues 300E

[retromobilia@xxxxxxxxxxx]

I receive and read numerous restoration magazines and this issue has come up in several issues. The most common solution especially in restored cars is the grounding. When many cars are restored most after long periods the grounding straps in various places (mainly the engine) were forgotten, overlooked or deemed unnecessary. Please do not depend on motor mounts and other frame connections for grounding. Many were probably painted or powder-coated and do not provide adequate grounding (even some old connections may be corroded and not grounding properly). 
A good way to check this is using an ohm meter between the positive and negative of the battery, and then between the positive post and other grounded areas, comparing the value to other areas like engine block, case of the starter, chassis and bolts , etc. The value should be as close as possible to the battery sample. If it is not similar try adding grounding straps (two or three) in several areas, especially from the battery to a good secure connection to the block (sometimes the battery ground is to the frame and is expected to be adequate and it is not especially after restoration and paining). I hope and believe this will help some.

problem: I don't believe my system is charging, or if so, not enough. 
1. Mopar guys who put car back together maintain they polarized the generator 
2. several different shops claim the system is charging 
3. ammeter stays at or just a hair under neutral on guage when running 
4. no noticeable draw on ammeter guage in car when turn lights on, hi or low beam 
5. significant discharge registered when heater fan is turned on 
6. problem is car often barely turns over enough to start when warm unless I have fully charged the battery 
7. have replaced starter 
8. have switched batteries with the F & no problems there 
9. drove it 80 miles or so, 1/2 at night after fully charging battery @ 2 amps over a day or so. slow starting reappeared 2 days later. 

Question: does this sound like voltage regulator is not allowing enough charge to flow; any other ideas? 
Would the charging system tests show proper charging if generator was not properly polarized? 
I am hesitant to drive it too far. 

Thanks
