I had the lower cowl off, so I have completed some jobs that needed doing. I adjusted the waste gate as per Rotax Maintenance Manual and safety wired the cable adjustment nuts. The alternator is earthed through the mounting brackets, however, it has been pointed out to me many electrical technicians recommend a separate earth strap. It may make no difference but I installed a dedicated earth strap from the external alternator to the engine block. I safety wired the TCU servo cable as per the maintenance manual.
