Help with finding what is going on. I am assuming a short or something is going out. I have an SCT downloaded to tow hall DTF gone.
Had an edge attitude removed it but still doing it. It has done it for about 6 month but recently it does it daily. Every once in awhile my anti theft comes on and can not start it. This has happened 4 times.

It has had cab removed twice once for the oil pan or plate to be replaced and once for new engine.

IF this was a Arctic Cat sled I could fix it but this is out of my specialty .

 

Check your batteries first. Load test each. If one is bad replace both.

 

They are new last year but just check and both test good.
