Great news! The correct 70 RR alternator has just been installed and I’m happy to report that the voltage is at 14.2@ idle..a lot safer than 18v
Happy hot rodder!
When I put the digital dash in and drove it around to calibrate the speedo,not knowing what I know now I’m pretty sure there was the high voltage running through everything. No excuse for not checking continuity. The dash is all low volt LED. What is your worry about putting the electrical back...
I found a great video on the Tube. It is a Chrysler co.vid from the old days. A lot of stills and two well dressed techs talking about the different alternator/VR’s of the day.
I have determined that I currently have an alt.from 1969,but I have wiring for a 1970…solution? Get a 2field for a 70...
Here’s the deal. I have more than one green wire in the area and if indeed someone put a 69 specific alt.on which it’s starting to feel that way. The ones for 70 are 2 field 1bat.
Just had an epiphany of sorts checking out the wiring diagram. This may look like a factory alt. But just not for this car. That being said the wire to the only attachment for the field is a faded blue and I also have 2 separate green wires that have never been attached to anything much less the...
From all I can tell the alternator is period correct . The service manual shows a spot on identical one in the book. There are 2 connections 1-field/1-black wire to the VR.
That’s it per the book.
In the area near the wires are a couple separate green wires with slide on connectors that have...
Also for what it's worth,the VR that was on it when i got it,my guys at the shop installed the electronic ignition in the distributor and a high output coil.
OK! Just got done with the test you suggested and here's what i got:
1.VR unplugged start engine and voltage on gauge and meter=17.2v
2. The only field wire disconnected w/VR unplugged=12.7v
3. Field wire unplugged w/VR plugged back in=12.7v
This alternator was with the car when purchased single...
It is a 70 RR w/383,this alternator was in it when purchased and it is a round back as they say. The one field location is grounded to the case and more accessible other field connection has what appears to be a grayish wire attached and the there’s the power lead running back to where it ties...
Sounds good! My alternator has one field wire that’s kinda gray, and I believe the second field is grounded and of course the lead wire to the VR. Should that be any different than some who have 2 field wires that can be unplugged?
Thanks for your patience
Is that full fielded voltage reading telling me that the alternator has an issue? Then I shall pull the fielding wire as well. Gotta try everything! Wish me luck and stay tuned
Looks like I will be taking the alternator out and heading for the repair shop tomorrow. Put in the Mopar VR today and no change on the meter at the battery and the digital gauge on the dash. At least they are agreeing with each other. The firewall on the RR.has the mounting plate that is all...
I will say I never had this issue when I had the original dash and gauges. My issue then was the ammeter gauge wire connections getting hot,due in part to old crusty insulation on the studs. Same alternator & VR. The ammeter wires got joined and wrapped up,so I never knew what was going on with...
I guess that push through the VR? sounded odd…sorry!
If the VR is doing its job I was under the impression that a high voltage number would mean that it was bad. Like I said I’m not good with electrical. Could any of the connections on the back of the alternator be hooked up bass akwards?
Never...
