hi, i have a 1992 argo magnum with a kohler m18 engine. the machine runs perfect and is a great rig for what i use it for.after my grandfather died i decided to restore it a bit since it was sitting for 3 or 4 years. all it needed was a new fuel pump and away it went.the only problem with the argo is that the battery dies really easy and i am after putting two new ones in. could it be the regulator (recitifier). if so please someone help.thanks!!
