Battery Dis-connect trouble

[tshirtman]

Having trouble getting the battery disconnect to cut power.
Installed on the neg post of one battery with a jumper going to the other battery neg post . First post has trailer ground and jumper on neg post. All the rest of the trailer wires are on the pos posts of both batteries.
when the disconnect is open I have power and closed I have power.
Very confused. Confirmed with an amp meter the disconnect is working properly.
scratching my bald head
Does anyone have the answer??

I suspect it may be where you have the jumper from one NEG post to the other. It sounds like your disconnect is just disconnecting one battery instead of both. Yes?

I think you need that connection to the trailer chasis behind your switch since you are trying to disconnect on the negative side.

I made the same mistake on mine years ago. Draw out what you actually have on a diagram and you will likely see that you are only removing one battery.

You are disconnecting the negative battery post from the chassis ground but your converter is still hooked up to the battery post ground?
What trailer?

It sounds like you installed the switch between the batteries. You need to relocate where you mounted the disconnect switch to a location between the batteries and the frame connection. There should be no other cables on the negative terminal

This might be a stupid question, but I am going to ask it anyway. When you were testing the battery disconnect, was your trailer disconnected from shore power and from the tow vehicle?

Just an attaboy to the Jayco Twin Falls plant.
Needed a replacement Lippert Components leveler sticker for my 3013 Jay Flight . Lippert wanted $2.50 plus $10.00 to ship to me.
Jayco Twin Falls stepped up and sent 3 for FREE and even paid the stamp to mail.
Thanks Jayco for being an outstanding manufacturer and showing what customer service is all about
