Battery disconnect relay

[flyfish6]

i have 2006 SightseerReplaced the solenoid and found a yellow wire disconnected from the relay. It is zip tied to heavy gauge red wire that connects solenoid to relay. I can't tell how to connect it.
The other 2 wires connect easily to the front.
The wiring diagram shows it goes to left side by the fuse. But dang if I can tell how. I touched it to the bigger red wire and blew something
Help if you can.
Thanks

Winnebago uses yellow wire for hot wires, white for ground inside the coach. The chassis uses red for positive, black for ground-usually. I haven't looked at my disconnect for more than a year so can't speak to where the wires connect.

flyfish6, what are the letters at the end of the wire number on the yellow wire?
Cannot find a good picture but the lug on the wire is part of the connector that the fuse plugs into. Sounds like the wire broke off from the lug.

flyfish6, here is a picture of a couple of isolation relays. The relay on the right has a yellow wire going into the bottom of the fuse holder, normal. The relay on the left looks like a repair was made by putting a jumper on the fuse holder and using some spade connectors to make the connections. You should only have the one wire going to the left side.

Thanks for the great help
That should do it as soon as I can get back to working with it.
Thanks guys

The numbers are ID numbers that are shown on the wiring diagrams you can download from Winnebago.

All wires have a number printed on them every 6 or 12 inches - don't recall which.

I am back to work on mh battery disconnect. Thought I had it right touched left big red wire on left side of relay Had my wife flip aux battery switch. Loud clunk. Now I have no 12 v except on shore power. Can't find a fuse blown. Could I have blown the relay?

As others have suggested, get the wire designation code that is printed on the wire. That will allow you to determine exactly what it is and from the diagrams, where it should be connected. Download the wiring diagram for your coach and check the back of the drawings for a description of the wire in question. There is a lot of current around the solenoids and connecting wires in that area without knowing exactly what the wire does is a receipt for causing extensive damage to your system and possible severe injury. Any electrical power work is not a trial and error process however with the information available in the wiring diagrams, can be done by a patient and competent do it yourselfer . Good luck and you can do it yourself with the resources available,
