7 Way Plug

punch50 · 04-20-2011, 02:57 PM

I have a 2006 Country Coach Inspire and need to have a charge wire run, which I believe is connector 4 on the plug. Country Coach did not install a wire to this connector according to my manual. Can someone tell me where the best place to connect a line so I can get power to this connector.
Thank you,
Judy

Others may disagree but I used a fused 30A #10 wire directly to the battery.

Welcome punch50 to irv2.
Have you checked for additional wiring back under rear bumper and up under dash may have wiring feeding to back for brake controller.
Wiring should be hooked up standard.

The US Gear instructions show that the batteries are connected DIRECT. They provide a fuse for BOTH the MH and the toad. We used the house battery bank.

I would go direct to a battery, or a lug that is tied to the battery with a really big wire. There is likely a big power post somewhere near your coach's engine or a nearby bay that would be convenient to power the charge wire on pin #4

HERE is the standard wiring used on the 7-pin Pollak connector. Tie pin #4 to a fused wire coming from the positive (+) terminal on the chassis battery(ies) or to a power post directly supplied by it so that the engine alternator can keep everything charged.

Rusty and others, thanks for the replies. My concern with tying the wire directly to the chassis battery is running down the battery when the engine is not running if I forget to unplug the trailer. The trailer has a small battery that keeps the breakaway functioning. I am going to try to take my motorhome to a service place next week to get this addressed. This doesn't sound like something a novice can do!!

That's easy to address. Install a battery isolation relay in the +12VDC line between the chassis battery and the 7-pin plug. This breaks the connection between the chassis battery and the 7-pin plug when the tow vehicle's ignition is off.

Most important--fuse the wire as near the power source as possible. Make sure the fuse rating is the lesser of the wire's capacity or your tow vehicle's 12V need.

I have a disconnect 45Amp relay near the battery adn after the fuse.
The relay is activated by 12 volts when the engine is running.
That way the 7 pole plug is powerless when "not in use".
Saves also on leak current in the connector by wettnes.

At 45 amps, you must run #8 wire, #6 to help with voltage drop. 45 amps seems excessive to any TOAD needs.

Way overcomplicated guys...

Open up your DC controller box. You will very probably find a spare fuse / circuit that is not used in your coach. We did in our PaceArrow. Just connect your wire to that. Try to pick one that is only hot when the coach is running.
