The wires from the alternator carry alternating current, so your voltage
meter has to be set to AC.
What is the battery voltage when the engine is running?
You can also disconnect the regulator from the battery, BUT KEEP THE
CAPACITOR CONNECTED TO THE REGULATOR! and run the engine (preferably
with all avionics switched off) and measure the voltage across the
capacitor.
Voltage for the standard Rotax regulator should be appr. 13.7 Volts.
Let me know how this works out so we have a starting point.
