5 amp BD Relay fuse keeps blowing

Hello,
First off, let me admit that I am a motor home Rookie!! We bought a 1998 Four Winds Wind Star. We have owned it for 2 months and has run fine until 3 days ago. Nether the Chassis or Coach battery disconnect switches will light up that are located just inside of the door. I have found the Intellitec Battery Control Center and found that the 5 amp fuse under the BD relay label was blown. I replaced the fuse and it immediately blew again. I'm thinking some kind of short right?

I worked on it all day, checked all voltages (check good) visually inspected wires and have found that all visually looks good.

Has anybody seen this before?

I have the Intellitec 05498. 00-0524-400

Thank You

My coach is a 2000 Pace Arrow Vision and I was having the same problem. I replaced the 5 amp with a 15 amp and it burned up the solonoid which controls the shut off for the coach. My advise is to leave it alone if nothing important is affected. I think the battery boster solonoid was the cause of this problem but I have no official confirmation on this.

Thanks for the reply. Unfortunately I have to do something because neither the Chassis or the Coach can get any power because of it. I did some more troubleshooting and found that I was drawing 17.5 amps across a 5 amp fuse so I most definitely a short somewhere.
I was able to jump across the battery disconnect for the Chassis and get the engine started so at least I'll be able to drive it to a mechanic if I can't find the source of the short.
My plan is to wire chase first then start throwing parts at it, least expensive first of course. I'm thinking of starting with the Chassis battery disconnect switch first. I just wish I could find a wiring diagram for my unit, that would help immensely.

Have you removed the small wire off the battery disconnect solenoid ? ( The one you jumped )

The solenoid could be shorted internally.
