Dear Friends,
Today, our venerable, original, power converter called it quits. Calling around, I was able to get a Progressive Dynamics 9200 series 60Amp.
Removing the old unit was "interesting" but it came out with a bit of struggle. It really is heavy compared with the new unit.
There are two leads remaining from the old installation. One, with a red tip, connected to the fuse block. The second is all black and disappears into a hole in the rear of the compartment. I am assuming the former, red tipped one is positive and the latter, all black one is the negative.
The PD unit has a place for positive and negative connections rather prominently marked. No problem there. There is a grounding lug on the chassis of the PD unit. The instruction booklet clearly specifies NOT to use the same wire to connect the grounding lug and the negative.
Do I utilize the grounding lug in this application? If I do use it, what do I connect it to?
Or, do I just use the positive and negative connections as the original was installed and discount the PD unit's grounding lug?
Thank you for your good advice.
Regards,
John+

Ground lug needs to be on a separate wire to the vehicle chassis. Suggest that you use a 10 or 8 gauge black wire. Probably overkill on gauge, but will hurt anything.
You will really like the modern PD charger.

John,
If the breaker box has a grounding lug or buss strip (green wire buss strip), ground the PD there.
If not, the shore power cord green wire should be connected to something in the breaker box. Use that.
It's only required when PD is plugged to 120 vac.

John,
Are you looking for bolts of cloth or installed on furniture?

The post in question is hot. Not a ground. Just passing that on to anyone reading this in the archive down the road.
One off line respondent suggested running the ground to the "aluminum frame of the coach body using a stainless steel sheet metal screw, a toothed lockwasher and a dollop of antioxidant paste to prevent deterioration."
I think this good advice as there is not a question of what pole the frame is.

To Bill from Texas (and anyone else interested),
I would LOVE to get the material on the bolt. Failing that, we might be able to salvage material from furniture and (especially) the large panel under the kitchenette window. Against all expectations, my wife PREFERS the yellow plaid. Shrugs.
I would also like to get two original Glenbrook seats if any are to be found in decent shape. The PO put in a seat out of some SOB and it sits "funny" to me. I'm tall and the seat has me sitting with my legs bent beyond 90 degrees which causes some cramping after a couple of hours driving.
Thank you

You are entirely correct. That post you see in the picture is the cable running from the front under the right side hood to the rear battery(s). It is a + 12 volt (POSITIVE) connection.
Back to your original posting. I believe the PD unit is grounded on the 120 Volt AC side through the 120 volt 3 conductor cord. I believe that 12 volt connections on the front have no internal reference to ground even though the minus side on our coaches is indeed body ground. (Something to think about, there are still a few vehicles around that are positive ground and this converter would also work there.) I also believe that the additional post that you are worried about connecting is grounding the chassis of the unit. It needs to also be connected to Body Ground.
So in your case 2 wires should be run to body ground. One for carrying -12 volt power and the other for grounding the chassis of the converter. I have mine wired that way with both wires attached to the body under the same bolt. It has been wired that way for about 15 years.
