battery cables

Probably goes to a relay and then to your coach batteries
When your engine is running it will charge your coach batteries

It may be going to the isolator that charges both house and coach batteries.

Let me ask the obvious question.....where does that cable go? Where does it attach to? That would be a simple answer, to me.
On any electrical issue, I go from the known to the unknown. You know it has a cable, find the unknown to where it goes. I would think that would be a fairly simple fix.

There is normally two cables on GM platforms. One goes to the battery disconnect and the other goes to the starter solenoid.
The charge relay is normally located in the battery control center under the hood driver's side. There is also an ignition relay located there to apply power to Fleetwood installed items.

ranakay,
Well Sir, in my opinion, you need to get that $93 dollar an hour to do his job an that is, investigate just EXACTLY where he thinks that "extra" cable goes. We can all send suggestions about where we think it might be going but, that does not do you any good. There are so many possibilities of where it might go and for what purpose, it would be really difficult for us to accurately tell you what it might be for.

Many electrical problems are hard to diagnose but, simply tracing a cable, from a battery post, is certainly not that difficult.

What kind of electrical problems are you having?

He hasn't been back since he asked. Maybe he didn't want an answer.

Is it a CABLE or a WIRE??:h

Cable should be #2 or bigger. Wire should be 12 or 10ga. could be a fusible link.....if it's smaller than a 12ga wire it would indicate an accessory...Dennis

Yeah Dennis,
That was going to be my next question but, we'll see what he says, if and when he returns with an answer.

Thanks for all the replys but I had to retire for the night, I forget this goes all across the country.
I have used the wrong word to explain my problem by saying "extra wire"it isn't an extra wire its just I think it got placed on the wrong battery by mistake and thats causing my electrical problems. Like the slide not going in or out the levelers not going up and down. With my slide out I couldn't move the coach. The mechanic came out to me yesterday and jumped the slide motor under the coach and got it to move back in, now I'm recharging my motor battery and this am will be able to drive it down to him for tracing it out and repairing the problem I hope. Can't figure out why a brand new motor battery would discharge with a battery charger hooked to my coach battery and a land line hooked to the coach. I just wanted to see a picture of the proper wiring to each battery as a guide line for him "mechanic" to make it easier. that way I could tell what is normal .
Thanks folks for all the help Randy
