I am away from home, but if I remember correctly, the start switch on the Skyview start module is rated for 2 amps. Dont know if the rating is continuous or intermittant. I have chosen to upgrade the switch to a higher capacity with unique keys.

I went to the 3amp fuse about 2 yrs ago after the 2amp blew. The 3a gives a blown indication which is better also.

The latest version of the POH has a 3a fuse listed on pg 2-6.

The originally specified 2 amp. fuse was based on the current requirements specification published by Rotax.
Field experience has demonstrated that their specification was a bit optimistic.

This thread deals with the problem. http://www.vansairforce.com/communit...ad.php?t=84329
It should be a 3a fuse not a 2a. But the ROTAX starts so fast that most people never blow the fuse. The starter relay pulls well over 2a. Vans approves using a 3a.

Default 3 amp fuse needed also

I hadn't read this thread, but initially could not figure out why my starter stopped working a few weeks ago after multiple uneventful engine starts in recent months. Was thinking the battery was weak sitting in a cold hanger and just needed to be charged up. Finally noticed the fuse was blown. The spare fuses that Van's supplies has a 3 amp replacement for the Starter, even though a 2 amp is placed in the panel. Live and learn.

I had this same issue occur during my flight down to Lakeland for Sun-N-Fun last year. Stopped for fuel and the restart attempt resulted in the 2 amp fuse blowing. Installed a 3 amp fuse, same result. I tied the tail down and hand propped the engine. Yes!! it IS possible. Flew on to Sun-N Fun and landed. Tried to restart after landing and has same result. Installed my last spare 3 amp fuse and left the plane tied down for 3 days. Upon getting ready to return home (NC), I fully expected to have to try to hand start the cold engine. The engine cranked on it's own without blowing the fuse!! Stopped for fuel at the same airport (KSSI). The attempt to restart resulted in another blown fuse, my last one. After another successful hand propping, the remaining flight home was uneventful.

Troubleshooting the issue at home resulted in finding one of the two start signal connections to the soft start modules had slipped out of the crimped connector. The bare wire was barely touching a metal bracket that was grounded. Installing a new terminal on the bare wire fixed the issue.

Tom,

I'd be interested in hearing more about your hand propping experience. I've been under the apparently mistaken impression that 250 RPM are needed to generate enough voltage to start. Even with the gear box advantage I thought that would not be possible. I took the ROTAX service course last year and the instructor reinforced this belief. He also stated that the new 912is gets ignition power from the battery so it does hand prop easily.

I'd like to know because it adds an option if stuck on the road.

Thanks,

Rich
