Hold the button???

in General Tech Discussion 3 weeks ago

Oh my back aches...

I got called out to download the ECM data on a 915iS yesterday and I was thinking that "surely, there must be a maintenance switch for this" as I had to hold the power button for several long minutes while the B.U.D.S. software extracted the logs.

While I am a pilot SEL as well as an iRMT and A&P mechanic, I've not flown LSA with Rotax injected 9 Series engine, let alone a 2025 VL3 being dragged along behind a 915iS

So the pilot walked me through the start procedure and included holding a power button and cranking until the generator came 'online' then the power button could be then be released...

So I found myself kneeling on the wing, holding the power 'moment button' for what seemed like tens of minutes. The only easy thing of all this was releasing and pushing this power button to cycle in / out of 'Maintenance Mode'

I was daydreaming about a maintenance switch that could be used to hot wire this button...

    The momentary switch is only used for engine start. There should also be an EMS or ECU backup switch, (used in case of a dual generator failure), which would not need to be held.

    Excellent, thank you Mike...

     

    I thought for sure there would be something. 

    The owner said something about another tech extracting the logs with the engine running...

    Is that possible too? 

    This download has been sent off via email to Lockwood. He first experienced this while under warranty. As the owner explained it, these will also be shared with Rotax proper as previous attempts to rectify this hasn't 'put a pin in it'

    Oh yeah, that 'guarded' battery backup switch was exactly what I was day dreaming about.

    I went back yesterday and downloaded another log after it had been flown over the weekend, then went for a ride along, then extracted a third log. The cockpit wasn't spacious enough to take a laptop to gather 'live data' in flight so we left it behind and went out and enjoyed boring a hole in the atmosphere. What a beautiful day it was in Florida to 'perform a mission'.

    Thanks again Mike.

    Cheers
