Johann, The Rotax starter contactor is rated at 75 amps, and the current draw can briefly reach the 100-120 amp mark, so a 30 amp fuse is definitely too small. If your friend really wants to fuse the starter wires, an ANL rated at at least 150 amps is in order, but he'll be adding weight for no real gain. There is usually no fuse on the fat wire feeding the starter motor on light airplanes. The rationale is that the battery is not able to overheat the big wire in case of fault. Rotax starter runs well with an AWG 6 wire. Of course the other wires should be protected by a fuse or a circuit-breaker.

If it is a new installation you might check to insure you have a good groun d to the engine. Make sure all contacts are clean and tight. Has the starter been check for proper operation. When power is applied do es it engage the ring gear and then stall (blow the fuse), or does it not e ven engage. Might need some grease.

At startup, warm-up and takeoff it is a steady 69-72. After about 15 Min's in the air it starts fluctuating from 79-92. It was even higher (99), with the Rotax oil filter. I changed to an after-market and it came down about 10 lbs. I checked the Oil Sender connections. The engine is running great otherwise so I'm not sure whats wrong. Any Ideas?
