Univolt replacement Question

I am replacing the Univolt in my 1972 Overlander. My question is. Is the univolt grounded anywhere other than the batery? I don't see a ground to frame.

Please excuse me if this is a redundant question, this is my first post and what a wealth of information I have gathered on this site.

If anyone has problems with round taillight cans like the ones on my unit, I have a fis for them.

I don't remember a ground from the chassis of my 71 Univolt to the trailer frame. However, my Intellipower does have a place to attach said ground. I assume this is due to new safety practices or code that was not in place in the 70s.

I'm in the process of changing out the Parallax in the Classic right now, it does have a solid copper wire from the housing of the converter to a common chassis ground.

I think it was grounded. It is grounded through the Ac feed wire... you know the one ...three solid copper wires one black, one white, one bare to a screw in the case.

Sorry but I don't know the exact correct terminology but it was grounded with the bare copper wire to the breaker panel then to the frame.

And the negitive terminal of the battery

My '73 has a ground to the inside aluminum wall going over toward the Univolt. Problem is I can't remember where it attaches on the Univolt end. You need that ground to make the running lights and a couple of other inside lights work. I'll take a look at it later today and post back here. Sorry I can't be more help right now.

Just looked at it. The ground to the interior wall is bonded to the main ground coming off the Univolt--the same wire that goes to the battery. Looks like a 10 gauge wire. That's how it's done in the '73. If your running lights won't work, I'll bet it's pretty similar. Let me know if you need more info (Pics, etc).
