Start button, Ground cable & ECU connection
1. Check that the start button closes the circuit to the starter relay – disconnect at starter relay and check
using continuity on a multimeter. Reconnect if good.
2. Visually check for presence and connection of ground cable between the engine and the airframe.
3. Check using a multimeter check for ‘continuity’, i.e. that there is no break from engine to the negative
terminal on the battery. This may require sequential readings, depending on the installation.
4. Check both ECU connectors are connected and that all wires are routed and connected i.a.w. the latest
installation manual for the engine. (available from
