My bet is a pair of gp 24’s. Maybe lucky enough to get 27’s. 6V is highly unlikely.

Thanks. Battery charger not needed. Found the transfer box; it is screwed onto the back of the breaker box / converter. Take the screw off and they had a diagram showing shore power in and genny in. The out goes direct to the breaker. The neutral was fried. Suspect the transfer box is shot and a replacement is on its way. I took the pos and neutral and tied the shore power leads to leads going into the breaker panel and the coach now has power when plugged into shore power. Was actually pretty easy. The wires going down into the electronics of the transfer part are much heavier aluminum and I just capped and taped for safety. The neutral wire from shore power and going to transfer were burned a bit and the wire nut was melted. The outside connector was tightened and resinstalled so all is good for now.

One question for those who know what they are doing. Going into a panel such as the transfer box or my breaker box in my trailer is a great plastic thing the wire bundle goes though it has an upper and lower clip that keeps it from being pulled out (that is what it is for I guess) and there is a wedge shaped bayonet that is pushed down into the wire sheath to retain the wiring. It appears the bayonet is a bit wedge shaped to keep it from being pulled out. Are these things re-usable? I didn't have any luck with the one in my camper where the power cable came into the breaker box area. The bayonet doesn't like to be pulled back up. Are these things one time use?

Thanks. Moot now that I have them back up on shore power. Chuck, you and a few others with a higher level of tech expertise are a real blessing on this forum. I am on other forums and no where near the expertise you guys have. Thanks to all who took the time to help... it DID help and got my sis and BIL back in A/C. We were lucky yesterday as it never got out of the low 80s and last night was fairly cool so it wasn't an issue and I am sure they thank you too.

I have reused them. A huge PITA to remove without destroying. I only used when no other strain reliefs were available.

I think this is what is needed:
https://parts.unitedrv.com/products/...nt=Catch%20All

Doesn't seem to come with strain relief fittings from the description. I looked online and didn't see any that looked like the ones in my RV or the one in my BIL's. They were both gray. I did see a lot of Heyco strain relief gizmos so if I am on the hook to install, will have him get some unless there is a better or easier alternative.

**sourdough** · 05-14-2021, 01:15 PM

Same here. IF you can manage removal without breaking it and you reuse it might make sure it still retains like it did before, or, just order some new ones for the future if it thinks it might want to come off.

Like Chuck I only reuse if there were no alternative.

cavie · 05-14-2021, 04:24 PM

if you can't make it work, just tape both sides to keep the wire in place.

wiredgeorge · 05-14-2021, 05:34 PM

If you reuse those things and mess up the bayonet, the little tabs towards the outside will keep the cable from being pulled backwards; Not sure how the cables could be pulled since the unit is behind the power center and very likely the cables have stays that are screwed into the floor, etc. My power cord had a stay that wrapped around and was screwed to the floor and the cable couldn't move without unscrewing it.

It's more a matter of vibrations going down the road causing issues like the cutting the wire on the metal box where they go thru.

wiredgeorge · 05-14-2021, 05:45 PM

That is the purpose of those plastic strain relief gizmos. There is one 3/4" and two 1/2" holes where the cables go through those plastic strain relief thingees and the cable can't move nor could it ever contact the sharp metal edge of the holes it is locked into. I just think it is a bit stupid to use those things that can't be released and reused but no one who does this stuff for a living asked me.

They are cheap (inexpensive), quick to inmstall, and not intended to be reused. Did I mention they are cheap?

**chuckster57** · 05-14-2021, 05:52 PM

They are common on RVs at the junction box for the umbilical cord. I suspect it’s a “no brains required” for the person on the assembly line- simply squeeze and push into the hole.

they are used in millions of applications throughout the electric industery.

mikec557 · 05-20-2021, 07:57 AM

I haven't seen a picture of the plastic ones, but since the holes in the transfer switch are the standard 3/4 and 1/2 inch holes, couldn't you find the standard stain reliefs at home depot? I seem to recall they carried both metal and plastic strain reliefs.

did you check it to see if it was fried??? or are you just a parts changer.

wiredgeorge · 05-20-2021, 09:45 AM

Since it is a 2021 Gulfstream Conquest that costs as much as my house and is still under warranty, I felt the prudent thing would be to just get their shore power working (temps are getting warm in South Texas). They will eventually take it into an authorized service place to have that thing changed or fixed or whatever. Since I have never opened one to the electronics parts, felt it prudent not to mess with it since they don't really need generator power while on our property. If I was forced to make a full repair, I would just swap it out as you can get then for under $60 and with no expertise or desire to learn how to fix a transfer switch, would likely swap swap swap.

Oh yeah, I am not a retired master electrician as I rebuild and sell vintage Japanese motorcycle carburetors and many of the messed up carburetor assemblies I fix come from retired master electricians!

And your point? Yes they are used a lot in residential application where non metallic covered (Romex) wire is used for the precise reasons I stated.

I understand you like to respond the way the character Walter talks on the Muppets but this type of response is not helpful and could be construed as trolling.
