battery disconnect

On a recent trip to N.S. Canada, there was a poorly “fix” to a seam on the Trans Canada in Cape Breton. Didn’t look bad on the approach. But after crossing it, figured the contents of our refrigerator (together with the door) would be on the floor. While that didn’t happen, I think this did...

Good day to you all! Hope you can settle a discussion regarding the battery disconnect switch. What position should this switch be in when connected to shore power, and what voltages should my lead-acid battery read in each switch position?

2005 Four Winds Class C 32’ Hello all, I have a battery question. I’m a retired HVAC tech very good with AC power but not real good with DC voltage. My question is I have been using RV only on 120 V but I was thinking about doing some Boondocking so I disconnected the 120 V but the coach...

Looking for some advise, I had a sudden loss of power and I believe it to be a fuel or ignition relay/fuse. 2001 Newmar Dutchstar, still runs solid.... until this afternoon. I'm camping in a wooded site, full hookups. Afternoon thunderstorms escalated with tornado warnings. Shore power was...

Just bought a new 2026 Cougar Travel Trailer. It comes standard with I think is a single 200w solar panel. It also has a solar disconnect switch. I'm used to disconnecting the positive battery lead when I drop my unit at the storage area. Do I need to do anything with that solar disconnect...

I did see there was another thread on almost the same topic but many of the posts were 3+ years old and I know lithium batteries have changed in that time period, so I'm starting a new thread. I have a new 2026 Caravel 20FB and plan to store it covered. It may be important to note that I live...

We recently bought a used 2021 GMC Sierra 1500 AT4 X41 4WD crew cab with two speed transfer case and neutral indicator on rotary knob. We have the 4 xfer case buttons under the round wheel and hit the 2H key 5 x in 10 seconds to shift the transfer case into Neutral, which lights the "N" letter...

Hi, this is a new to me motorhome. I understand the house batteries are supposed to operate the lighting inside when rv not running. I have no power inside with house batteries but wben connected to shore power everything works. The battery disconnects are off and operate fine and batteries are...

My salesman switch no longer disconnects the batteries. Is there a fuse or do they get stuck? The batteries are providing power and I almost never disconnect so they electrics are working both 12v and 120.

My chassis electrical all works fine but I have no power in the coach and understand that I need chassis power for it to work. I'm certain there must be a chassis battery breaker, but can't find it. Has anyone encountered this issue? I don't see it in any of the other threads. New owner :)

I purchased a new 2026 Apla Wolf 280QBS and it has solar on the roof. I park it at a storage location and set battery disconnect to off and pulled key. I checked the powered jack and it worked along with the light. I opened camper door and panel just inside was off. I was surprised the jack...

I am replacing 7-pin pigtail and want to kill power to 12VDC aux power (black wire terminal) in the pigtail terminal box on my 5.0. There is no shore power and battery disconnect is open but aux power is still live. Do I just lift a battery terminal?

Hi all, apologies if this isn't really an issue but I'm still fairly new to trailering and just had a question about a potential phantom power draw in my 2018 Salem Cruise Lite. I've connected two 12v batteries in a parallel configuration and have no issues when the batteries are full, so I know...

The green light on the so called “Battery Power” switch button (I realize this is not a complete battery power switch and I installed a real one at the battery box a couple of years ago) goes off, sometimes more than once in a minute, and then comes back on after a few seconds, from two to maybe...

We recently purchase a 2023 Forest river Flagstaff 26 trailer . We are having problems with no 12V power when unhooked from AC power. Inverter has solid red light on, there is a AC master reset button on back of inverter but either isn'nt tripped or I can't figure out how to switch it. We...

Hi- To flat tow my Colorado I need to disconnect the battery. I also use the Blue Ox patriot braking system and need 12v power. What’s the best way to accomplish both the battery disconnect and the 12v power needed? I tried using an auxiliary 12v power source - a ryobi 40v power station - but...

for RV storage, do you use a battery disconnect device? What makes have you tried? Which are the 'best'? Use it on the truck? The house? Both?

Hello, I have a 2017 ACE 30,3 TV and I believe my battery disconnect switch is bad. Can anyone give me a part number and supplier where I can get a replacement?

I have a new Winnie Thrive with a 12 volt Furrion refrigerator. After we turn it off, leave the trailer, we shut off the battery connect. If for any reason we need to turn the battery back on (through the disconnect switch) the refrigerator automatically turns on. So we have to be sure to go in...

Hello everyone I just got a Roadmaster battery disconnect for our 2025 Chevy Colorado and it disconnects the Positive cable. I've always believed the Negative cable is the one that should be disconnected. Anyone using one of these? Does it cause any problems? Thanks

I need something with more cargo than my Jeep TJ and was looking at 07-11 JKs. Below are some instructions from the towing sections. Is this what you all are experiencing? It is not clear but appears that Steering Lock is finally gone in 2011 but they still want the key on ACC? It appears...

Battery Disconnect not working, 2015 Thor Freedom Elite 28h, Ford E450 Shore power works fine, 2 months ago the Ford charged batteries well. Two years ago, I replace the converter with a WF 8955AD (50 amp Auto Detect) and seemed to work fine. Last month, dry camping, the dual batteries (3...

New first time owner of a RV and unable to locate a coach battery disconnect switch. Searched high and low to no avail. When coach battery is charged up all 12 lights work however, unable to disable the coach battery and it drains overnight and having to re-charge. Would appreciate any help.

Hi there folks! I'm posting because I have troubleshooted to my wits end. When I first got my rig - 1995 Kountry Aire 37' Ford 460 v6 7.5 ltr Motorhome Chassis the coach battery worked fine. Then the electric stairs got bent a bit and wouldn't retract all the way. So it made a little...

I recently started towing a 2015 Smart ForTwo. The owners manual states that a battery disconnect should be used to 1) prevent data loss in the vehicle's control units; and 2) prevent the vehicle from locking. I installed the disconnect, but when I reconnect the battery, it takes anywhere from...
