bdensford Report post Posted February 1, 2017 I installed a physical disconnect device on the ground side of our deep cycle camper batteries. The purpose is to avoid over charging at our own lot where we have 50 amp shorepower. When we pull the lever at the battery location to open the circuit, DC power seems to start out okay then gets dim and 12 volt appliances start acting improperly. Where is the problem?

wolfe10 Report post Posted February 1, 2017 Check voltage with a digital voltmeter from both sides of the battery disconnect switch to positive terminal of battery. Compare with reading from battery positive to negative terminal. Share this post Link to post Share on other sites
kaypsmith Report post Posted February 1, 2017 I had the same problem with a blade type disconnect switch. Check as Brett said, but that same check didn't reveal the problem unless under load. I changed to a 200 amp air conditioner quick disconnect made for AC voltage but has worked well for me for several years. Share this post Link to post Share on other sites
wolfe10 Report post Posted February 1, 2017 If you are looking for a high-amp, quality disconnect, here you go: http://www.perko.com/catalog/battery_switches/99/heavy_duty_battery_disconnect_switch/ Rated 450 amps continuous. 1200 amps intermittent. Used them for years on our boats. Share this post Link to post Share on other sites
manholt Report post Posted February 1, 2017 Brett, speaking of boats, I know you'll be in AZ. But when will you sail the ocean blue again? Carl Share this post Link to post Share on other sites

Carl Carl, We are seriously considering selling the coach and going back to the sailboat (The sailboat is lonely just sitting in Kemah and remembers several great trips to the Bahamas). Will probably list the coach for sale right after the FMCA Chandler. Should be a quick sale-- as you would suspect, it is in extremely good condition. With our last two coaches, had people standing in line when we sold them. Share this post Link to post Share on other sites
manholt Report post Posted February 2, 2017 Brett. Will defiantly miss you. But I totally understand. The Ocean and Islands is a 180 degrees from RV'g... why I'm still looking for another 42 foot cat. BVI is my favorite, especially Antiqua ! Used to be Caymans...still have 2 condos there, on vacation rental program in the yacht basin. Getting time to sell. You keeping house? I'm not.
