Thread: Voltage regulator woes

Tweet

My voltage regulator seems to go bad on me every few weeks.
Could this have anything to do with the battery being the wrong size?
It is small and old, and not the right one for the car.
I have checked all of my other wiring, and everything is in good shape, and my alternator is less than one year old.

It is a 1965 Chrysler Newport 2DHT w/383.

I DON'T REMEMBER ANY ONE PROBLEM WITH THE CHRYSLER'S , back then. do you know the reg. is bad or is your bat. going dead, you're putting on a new reg., charging the bat. and its ok for another few weeks. if your bat. is low the alt. won't charge 100% so it could be the bat.

Surely you jest! The factory alternator on that car is only rated at 46 amps
I wish I could find a bigger one.
Though when I took it to the auto parts store for testing, they said it was fine.
I do think it is the battery. Now I just have to save my nickels, dimes, and some aluminum cans to get another battery.
Then I have to get yet another voltage regualtor.
Wish I could find a nice high output alternator with internal regulation like I used to have on my Chevy.
Man that was easy!

thats about all any of them had in 65. a bad bat. shouldn't burn up your reg. why not put a built in reg. gm alt on the car. if you can mount it, it will work just like it does on a gm car. helped a guy hook up one on a 63 289 ford not long ago. works great.

Those era chryslers had a problem with the main wiring connector on the fire wall,the wire comming off the alternator that charges goes through the connector and through the amp gauge sometimes causing the connector to melt making a no charge situation. I had a 68 newport which is mechanically and structurally the same as your 65 and someone rigged that connection,what I did at first was to repair the connection and add another wire to the battery post of the alternator and hooked it to the positive post on the battery and you have to leave the original wire as its the main feed for the car. Even though I installed a newer style alternator and regulator when I installed electronic ignition I left the extra wire to the battery so the charge would not have to go through the amp gauge before it got to the battery.

This will solve your problem.
