Hi I can't see a problem with the Kev Mod. unless it was fitted incorrectly, I would suspect after 6 weeks of inactivity that maybe moisture or dump have worked their way in some of the wiring loop usual suspects are those under the tank. Lift the tank and inspect wires and jumpers for corrosion. Any green growth that shouldn't be there should be brushed off with a wire brush, then rinse connections with WD40 allow to dry and start again. Meantime I am directing Kev to this thread as he can give you other pointers in relation to your issue.
