I was doing a lot of mud this week-end and after taking a break I ad to start it up with with the manuel rope the battery was complete dead so dead that I had to borrow an other quad battery to comme back at my house because it wouldn't start at all after couple of stops. then the day after everithing was working perfectly ? it was charging 14.9 v the battery was at 12.1 v on my multimeter
is it possible that the magneto could have been splash by some water? all my connections look prety clean !
just brought it back from the dealer and he didn't find nothing !!!!!

 

oil ok? is it milky? Air box clean?

 

yes everything is ok, no water in the oil , I see only two posibility either something like the winch or the heater for the hands has a problem sometimes and drain the battery or some dust or water got into the charging system
thanks anyway !
