WirthCo20314 Battery Doctor Battery Water Resistant Master Switch

I ordered two #20314 WirthCo Engineering Water-Resistant Master Switch to install one in our Jeep. I installed one on the negative side of our 2009 Jeep Wrangler battery as a kill switch to the electrical system to satisfy Jeep's requirement when towed by a motorhome. The switch worked well for three months and it developed an internal disconnection problem which killed the engine when driving the Jeep. I installed the second new switch while on the road & it operated all of five miles down the road until it exhibited the same disconnection problem. I removed the second switch and use an alternative method to disconnect the Jeep's electrical system for towing. I have not disposed of either switch in case WirthCo wants to study the switches for improving future internal function design solutions.

I ordered two battery master switches both units worked for about 1 month. What a waste of time and money, ssems to me that the weather affects the operation of the switch. When all is dry and no humidity the switch worked fine. I live in a climate that does get rain and when you have the switch installed on your RV to disconnect the battery when in storage the key out of the unit. This causes water to enter into the key hole. It is my opinion that this why the unit fails.

well made

ORDERED THIS TO REBUILD OUR TEARDROP TRAILER WIRING AS A MASTER SWITCH FOR THE BATTERY. I HIGHLY RECOMMEND THIS TO SAVE BATTERY LIFE.

Works great.

Love it!

great for a power disconnect.
