Generator wires guidance required

[harmony]

My car is a 48 Chrysler 6 volt positive ground and I should start out by saying it charges fine and holds a charge excellent.  I've had the car a couple years and never had an issue with a sluggish battery.  I put a load test on it out of curiosity and it was fine at 5.6 volts.  It is around 6.5 volts when the car is off. When I'm driving along the amp gauge is about an 1/8th of an inch to the positive side of the gauge. Pull the head lights on and it drops to maybe -25 for a split second and then returns to where it was.  

So going by the theory, "if it ain't broke don't fix it"  I've had no reason to investigate the generator wiring.  Other than making sure all contacts were clean and tight.   I've just noticed that the wire from the starter to the generator on my car goes to the F terminal.  In the manual it goes to the A terminal.  

Does anyone have any thoughts on that?

Field receiving power during startup should not affect it, but regulator resistors may burn. You don't state charging voltage when under load or current draw after start. 

The build in safety feature of not be able to activate starter while engine is running is removed and wire should be moved to A.

Any idea why someone might have run that wire from the starter to F ?   So are you saying if for some reason I hit the starter button while driving along the starter would engage.  If the wire was connected to the A terminal and the starter button was pushed, nothing would happen?

Theoretical and far fetched, if these 2 resistor that magnetize the field coil for correct polarity are burned, Build in starter relay coil could substitute this, but .........I recon it was someone in a hurry

 

Correct, connecting to A, starter will not engage while engine running. Assuming your car is still positive grounded, starter button switched minus to starter relay (not solenoid). Other side of relay is connected to A on Gen and acts as a ground to energize solenoid for start. When engine is running and charging, A becomes hot (minus) . Minus on both sides of starter relay will disable it. Chrysler where smart.

Ok thanks, I'll change that tomorrow.  So obviously I'll pull the ground off the battery when I move that wire.  Should I be polarizing the generator after I reconnect the battery?  I know about polarizing the regulator, but while researching this, I read about polarizing the generator.

Never heard of polarizing regulator. You polarize generator for correct polarization (minus) at A terminal if generator has been dismantled. No need to but no harm if done again.  If generator is connected to regulator, it can be done on regulator.
