Hey all, my truck is up and running, but now I've noticed it's overcharging. I cleaned all the contacts in the VR, as well as all the connections and it's still pushing 11+ volts to the battery. Not good. I'm sure the VR is a common item..Anyone have a Napa part number?

hopefully some one has a number. I was thinking that these may have been adjustable?

Yep, you're right, all VR's are adjustable, but I think mine has a dead coil...fail.

I found this box in my K1. Maybe this will help. I didn't open it to see if the part number matches the box.

Starting with the MT-52D IH parts manual which lists IH & Delco-Remy #'s ...
Ran the Delco-Remy #'s on the Remy site,all are obsolete.Next was to cross reference all the PN's at Standard Motor Products (SMP).

As for the PN from Rick's pic. It doesn't cross to SMP nor come up on a web search.
Trying some of the applications on the label got many other PN's. VR-1 came up twice.
Here's a link for SMP

SMP doesn't list IH previous to 1950 in application look up's, VR-1 does show for a '50 L-110 though.

Tonight I did open the box and it looks like it is NOS. The paint has rubbed off onto the bag. I couldn't find any numbers stamped on the VR. Only Delco Remy.

Oh well. I have the original 6 volt VR but didn't look to see if the numbers match. Let me know if you want me to continue the search.

6v, POS ground VR's with the 3 hole mount are still available from NAPA. Let me see if I can track down the PN.

The SMP #'s I posted are all good. Rockauto for one stocks them all.Just bring PN for the application with you to your FLAPS and they can cross it.

I wouldn't have posted PN's that weren't good!

Scottso, I hope you didn't take my post as a shot at you, because it certainly wasn't meant that way. I was just adding to your as always thorough reply!
