I own a XP200 and is a great running motor. I ran into a couple problems this past winter. The first thing I noticed is the Tach quit working, It will work occasionally. The second is my battery will not charge. I am thinking that this is one in the same problem. I replaced the spark plugs due to rough running (thought it was fouled plugs). The plugs didnt change anything so I am assuming it is tied into my other problems. Could it possibly be a rectifier issue? I have a manual ordered and on the way but it will be next week before it will arrive. Any help would be appreciated.<br />Thanks,<br />Lectro
