You may want to inspect the wiring from the battery box to to underside of the flooring. Make sure it encased in a protected covering. Most of the wiring is encased in vinyl tubing from the factory to protect from the weather.

I found on my 2206, the factory ran a 10ga wire under the floor to power the lifting switch with no protecting covering, through the metal floor supports and started rubbing the insulation on the wire. I could see it would be a short in the future. I covered this wire with a wire loom cover with a split in it for easy insulation. I had a extra piece of it laying around but you can find at any auto parts store.
