coolant fan stay on

[frank11]

Hello all I got a problem. I have a 2008 mc54 250B scooter. I put it in the shop to change the headlight switch . When i got it back everything was fine. I started it and the coolant fan came on and stayed on it never did that before when the temp. would rise the fan would come on the temp. would drop back and the fan would go off. The shop said that the wires that he changed when he installed the switch has nothing to do with the fan I think that since he had the dash out that he might have crossed a wire or something like that. I don't know .I checked the water and it was a little low about 1/4 of a quart It started to rain and I never got a chance to get it warm . has anybody else had a problem with the fan coming on when the engine starts? could use any help. Thank you
