deadstick Posted June 14, 2017 Share Posted June 14, 2017 Hi, want to start an info sharing page for the 912is in a view to helping diagnose issues etc. Had a strange issue, pilot tried to start 912is with a low powered battery, no joy. Upon replacing the battery he found that the Engine management system would not turn on, this caused all systems to not work, fuel pump, start relay etc. could bypass them all using the emergency back up battery switch however the EMS still would not display. Fault finding the system, I kept coming back to the EMS unit and upon removal I could hear a rattle like something loose inside. After speaking with the manufacturer it turns out that trying to initialise the EMS with less than 6 volts causes a small capacitor that's soldered to the board to heat up and de- solder itself. So always keep your battery charged or start the engine with the backup battery armed and switch it off post start. 2 1 1 Link to comment Share on other sites More sharing options...

Downunder Posted June 15, 2017 Share Posted June 15, 2017 What amazes me is that Rotax know about this but have done nothing to eliminate the fault. A battery could lose charge for any number of reasons..... 1 Link to comment Share on other sites More sharing options...
Guest alpipete Posted June 17, 2017 Share Posted June 17, 2017 Yep a small solar panel is the answer,Since I installed one on my hanger the battery is always fully charged,such a simple solution.Happy flying Link to comment Share on other sites More sharing options...
storchy neil Posted June 17, 2017 Share Posted June 17, 2017 alpipete you will find that the battery will last five or seven years have battery in kia car that is ten years old that little solar panel cost nothing neil Link to comment Share on other sites More sharing options...
Steve L Posted June 18, 2017 Share Posted June 18, 2017 I run my whole hanga on solar as mains power was too expensive to get connected. The whole solar system only cost me around $500. There's always a coldie in the 12volt fridge, can run lots of 240 volt appliances through an inverter, 4 45watt LED forklift floodlights are heaps bright enough for lighting. Connect any idle battery to the system via 2.5mm jumper leads..... and in 5 years never had a power bill. Link to comment Share on other sites More sharing options...
