Hey guys, I'm having an issue with charging.

I removed my alternator a while back and when I re-installed it, the charging system wasn't charging.  When the car was at a buddies shop and we were doing the suspension, I mentioned to him about the issue.  He re-seated the field connectors and then it started to charge.  BUT, driving it home I noticed the system was charging too much.   When I accelerate the system would start over charging.   I just took it off again and was checking the spring/magnetic connectors on the field wire connectors.  They looked okay to me.  I re-installed, and now it's not charging again.  

Stupid question... Can the field wire connectors with the spring and magnet go bad?  

This is for my 68 Coronet.  It is a two field alternator.

Thanks!

 check to see if the screws that hold the field male spade connectors are loose ,  scratchchin then make sure the voltage regulator has a good ground

Tan Top, thanks for the picture.  The alternator on this car has different connectors on it for the field wires.   I'm pretty sure this is the issue, since everything started because of it.  I was going to put the right style alternator on it anyways, so I think I'll go this route next.   

I thought I read the Electronic Voltage Regulators are self grounding inside?   I did just put a new one on it (Mopar Performance) thinking this could have been the issue.

The "two field" supplies keyed power to one field and the regulator varies the ground to control the voltage. If the green wire is grounded between the alternator and the regulator, the  voltage will go to max...same if that field is grounded internally.

Alright guys.   Now I'm really frustrated.  

I received my 70 Alternator (original looking), put it on this morning and my charging issue continues.   it is showing a negative drain (-10ish) on the Ammeter.

Here are some readings I found -

Battery - not running - 12.54 volts
Batter - running - 12.28 volts

Disconnected the battery, and the reading from the green field wire to the connector on the alternator field is .498 on my ohm meter.   The blue wire showed .498 also.

I have a 70 style charging system -



Any suggestions?

I forgot to add - I tested this with two voltage regulators and two alternators.   The car has new wiring throughout.

Figured it out.   The Voltage Regulator didn't have a good ground on the firewall.  cheers

I ran a separate ground wire from the rear passenger engine block to the voltage reg. Needs a really good ground. 2thumbs No problems cheers
