[GMCnet] Battery line going from house to engine batteries [message #352401]

I am in the process of rewiring pretty much all the internal wiring
(mostly 12v, but probably will end up doing some of the 110v also). In
the process I need to replace the line that runs from the house
batteries up to the engine compartment. What is there is corroded and
most of the insulation in the engine compartment is breaking off. West
Marine has wire up to 6 AWG, but it seems that the wire that is there is
a larger gauge. I checked O'Reilly's and they can order at least 000
gauge. I would rather have a marine cable that will hold up to the
elements better, but I am not certain what gauge is there or should be
installed.

Does anyone have any idea what would be the appropriate gauge to install?

Thanks.

Gerard,

The original wire there was SAE #1, that is actually about 90% of #1 AWG. If you upsize that cable, more than that it really will not get you a lot as the other conductor is still the coach frame. Nothing wrong with going larger except the cost. Remember that welding cable is fine stranded and easier to bend, but it is more difficult to terminate effectively and the neoprene jacket is not very abrasion resistant.

You can also shop the marine wire suppliers online. (Almost anybody can beat Waste Marine) Those cables are also fine stranded and should be tinned for corrosion protection.

For those that are interested, I think we will be selling 35' pieces of stranded cable at the GMCMI spring Rally in Patterson. Can't remember what gauge it is. Maybe someone here knows. Selling it at $1.00/ft. We have several large spools of it that we have been carrying around for too many years and just trying to lighten the load. See you there!

Please see if you can find out what gauge and color it is.

Ken,

Mine is red, but my 73 still has the house bank in the front.

The later coaches I have worked on do have a Red #1 going to the back. This agrees with the published schematics.

I annoys my no end that SAE has their own undersize wire specs.

I am pretty sure it is a #1 cable -- at least the sizing is about right.
I did not know that SAE had their own gauge standard, but I will go with
1 AWG since that is what everyone is selling. Pretty sure the color was
red also, but the majority of the insulation has cracked and chipped off
inside the interduct.

Mine is red too. I was asking Larry what size and color the pieces of cable he is bringing to Patterson were.

My electrons do not like black cables.

Ken,
I have a note out to a couple of people that are on the set-up team in hopes that they know gauge. No response yet. I do know that the wire is Black and stranded. It was used many years ago when Ralph was in charge and they used it to electrify tents and other places that did not have adequate power for the GMCMI rally. I'll post more info as I get it.

OK Larry, that is going to be multi-conductor 10, 12, or 14 gauge cable used for 120 or 240 volt AC connections. It will not be heavy single conductor cable usable for batteries etc. in a GMC.

I was just joking on my previous comment about red cable.

Ken, teach them to alternate and they'll like black cable.

If it is split 240, one 120 hot is black, the 120 hot is red. White is always common in AC wiring. Green is safety ground. There are rules that an appropriate electrician can tell you the FEW places where white is tied to green.

Wow, you are really going to confuse my electrons with your suggestions. Some of them just might jump ship and get lost while looking for the correct color. It is like you going to the parking lot in the local mall looking for your white car to get home, but ending up driving there in a green one instead.

Some electrons always get confused and lost.

That's why we have Voltage Loss.

For real, could we measure the total cross section of the wires when they're parallelled? For a wire bolt and insulation that wire might work quite well and it should be somewhat scuff resistant. There's probably a stubby connector at Advance or on eBay with the clamp on
I bet Advance has a crimper they'll lend as well.

Mine is shot, replacement is in order.
