I have a 1997 Fleetwood Southwind 35' wide body 450/454, with two 12 volt batteries and I think there's an extra cable hooked up to the positive side of my motor battery. Having electrical problems and the mechanic thinks there's an extra cable on the positive post instead of being hooked to the coach battery. I sure could use a photo from someone who has a like RV to send me a pic of the proper hook up. It's costing $93 per hour and I need help lol. Thanks folks

Probably goes to a relay and then to your coach batteriesWhen 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. Scott
