Connecting auxiliary power supplies
Should you be unable to start the engine due to a weak battery, auxiliary power supplies can be con-
nected to help starting the engine.
To connect an auxiliary power supply use battery connector cables with clamps at either ends.
Connect the negative (-) wire to aircraft’s exhaust (sticking out below the engine cowling).
The positive (+) wire leads inside the cockpit to the relay mounted top-right of the aircraft’s battery
on the firewall. This relay has 3 nipples; the positive (+) wire must be connected to the upper-left
nipple, the only one to which 2 cables are connected to.
After you have connected the wires correctly, start the engine normally by pressing the starter but-
ton in the cockpit.
WARNING! The pilot must be in cockpit when starting the engine. The person who will
disconnect the cables after the engine has started must be aware of the danger of spinning
propeller nearby.
