A friend has an aircraft with a wind/propellor driven generator controlled by a "Ford type" regulator. The aircraft made its first flight in 6 years recently and the regulator was completely fried. Everything inside was heat damaged and the insulation on the wires entering the regulator melted off.



Where do we start looking?

Thanks

Mike,

1. Do you know that the wiring was good before the flight?

2. Part numbers / nameplate data for generator & regulator?

3. How many amps can this generator generate?

4. It's a generator and not an alternator?

5. Any pictures?

How many wires are coming out of the generator, 2 or 3 or ?

Do you know if the output is AC or DC? If not, can you measure it?

I suggest that the generator be disconnected from the aircraft electrical

system.  Then connect the generator output to a high wattage load such

as an automotive headlight and go for a test flight.  Measure the AC and 

DC voltage and current through the load.  If you suspect the unregulated 

generator voltage and current might be too high for a single headlight,

connect two headlights in series.
