Try an email to mike at the tryals shop in the US,as burkett may be in scotland. Seems a little black box, regulator or rectifier? Quote Link to comment Share on other sites More sharing options...
bigmike1961 Posted May 10, 2012 Report Share Posted May 10, 2012 (edited) If the fan is working properly it won't do that. It should kick in when the coolant gets too hot and turn off again when the fan's done it's job. Either the thermostat is bad, the connections are dirty on the thermostat or elsewhere, or the wiring is bad somewhere. On my scorpa there is a connection under the seat, 3 wires in with a white connector, the two outer wires are connected by a simple loop, that connection was poor - I ended up bending the contacts to ensure good continuity. If the coolant gets too hot it will boil. You should have a black plastic tube from the top of the rad cap to take overflow away down to the bash plate area. I have the pipe pointing outwards to make the escaping steam obvious. I carry a small jumper wire to bypass the thermostat and have the fan permanently on incase he thermostat doesn't cut in. Hope this helps. Edited May 10, 2012 by BigMike1961 1 Quote Link to comment Share on other sites More sharing options...
