elusivemite Posted November 3, 2015 Report Share Posted November 3, 2015 http://www.lewisportusa.com/manuals.htm the wiring harness diagrams might give you a clue. Used it to help troubleshoot somebody's poor job removing the lights on mine. Quote Link to comment Share on other sites More sharing options...
lineaway Posted November 4, 2015 Report Share Posted November 4, 2015 The two wires from the switch go to the thermostat. It should not have been wired to a switch in the first place, just hard wired on. Quote Link to comment Share on other sites More sharing options...
paulr1983 Posted November 4, 2015 Author Report Share Posted November 4, 2015 Is it that simple line away ?? Quote Link to comment Share on other sites More sharing options...
huski Posted November 4, 2015 Report Share Posted November 4, 2015 Yes,the the thermostat is just a heat activated switch,which effectively joins 2 wires together above a certain temperature Quote Link to comment Share on other sites More sharing options...
collyolly Posted November 4, 2015 Report Share Posted November 4, 2015 You say you still want to use a switch if you find the thermostate fails, well you simply wire it in parallel with the thermostate. Imagine a ladder with the rungs being the thermostate and the switch with the wiring connecting like the side rails. Quote Link to comment Share on other sites More sharing options...
lineaway Posted November 4, 2015 Report Share Posted November 4, 2015 I remember a guy that was riding a demo had a switch. In the excitement of the moment he forgot to turn it on. The little steam explosion was entertaining for the crowd, but not for the rider. Quote Link to comment Share on other sites More sharing options...
paulr1983 Posted November 4, 2015 Author Report Share Posted November 4, 2015 So basically wire it up normal then just put a bridge back between the two wires with a switch in the middle ?? Quote Link to comment Share on other sites More sharing options...
collyolly Posted November 4, 2015 Report Share Posted November 4, 2015 Yes that sounds right, hope nothing gets lost in translation here ! This means you can either let the thermostate operate automatically or over ride it with the switch both options will work. Quote Link to comment Share on other sites More sharing options...

scottwitting Posted November 5, 2015 Report Share Posted November 5, 2015 After having my thermostat fail during a trial, nearly boiling my bike and not being able to finish, I now carry a small link wire (6mm male spade each end if I remember right) that can now be quickly used to link out the thermostat and make the fan run all the time. I also run the bike up to temp and watch for the fan cutting in after each wash off and carb clean. Quote Link to comment Share on other sites More sharing options...
