The electric lift on my TS115 has stopped working from any of the controls i.e. the lift handle, rocker switch or mudguard switches, I found a burnt earth wire on top of the gearbox and have repaired but the fault is still evident, I have replaced the ecu with a known good unit and the fault is still evident, I don't have any fault codes as the dash is not displaying lift or gear status but hasn't for a long time even before the lift stopped working, I have checked the lift height potentiometer, control panel etc and they all seam to work fine, I have checked the wiring which is all intact, is there something that I am missing?
