2017 Denali Battery Disconnect

We purchased a 2017 Denali 289RK this past spring and I'm trying to determine if it has a factory installed battery disconnect. I contacted their tech support folks, and the response was "I think it should". Does anyone know for sure or where would be the most likely places for it?

Thanks in advance
Mike

Mine didn't come with one. I installed this https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 inside of the A-frame by the batteries.

Although I don't have a Denali my Voltage came with a factory one mounted in the cargo bay. An odd place and it did not isolate the battery. All the Co2, Propane gas sensor, and the smoke alarm still operated. What else I don't know but the bottom line is the factory is useless. I recommend putting a shut-off switch in the battery compartment. This way it will turn off everything and your battery will not be dead in a week. It's a suggestion. I would forget about the factory one if you have one it's probably wired the same.

Thanks for the replies. I guess I'll be installing my own. Looks like a pretty easy install.

Install on the negative cable.

I added a Cole-Hersey (sp) switch to mine in addition to adding a second battery. I had to modify the battery tray and placed the switch right next to the bed for those long cold nights at elk camp when the furnace is on a lot. When the battery gets low, you just roll over and flip it to the backup. Works well. Mine shuts everything down when it is in the off position allowing for long periods of inactivity and still having a fully charged battery(s) that are ready to go.

Any suggestions on the size of battery cables?

any larger cable. I suggest at least AWG 2. The smaller the number the larger the cable. If you can find a battery distributor near you they usually can make custom cables. Make sure the ends are soldered and not just crimped.

The 289RK is a 30 Amp rig (house wiring). AWG 8 will handle 30 Amps but you might want to go with AWG 6 to be on the safe side. Also for some reason I have found it easier to find AWG 6 primary wire at the auto stores than AWG 8.

But for wiring batteries together go with the AWG 2 that Tanman recommends. 6 Gauge from the battery to the battery disconnect switch however. My switch is connected to the positive terminal. I didn't want to mess with the integrity of the chassis grounding.

Also, look for something that looks like this somewhere in the vicinity of your batteries or on the A-frame. Your battery plus wire probably goes into one of these. There's a self-resetting circuit breaker under the rubber cover. The battery wire should connect to the copper terminal and the house wiring connects to the brass terminal. You want to install the cutoff switch downstream of this device to maintain protection at all times.
