The advice you got is right, and dumping the power into useful loads is a good idea. The regulator is not "poor" just very simple. It's a shunt regulator that keeps the voltage clamped at about 14 volts. Because the permanent magnet "dynamo" has no way to control field current, you either have to dump the unused power as heat (which is why the regulator gets hot) or use a much more sophisticated switching regulator like some motorcycles do. The Rotax installation manual calls for a maximum of 80 degrees C for the regulator.

Does anyone have a good source for the temperature recording strips that Roger mentions? I believe that the official ROTAX part number for these strips is @ $68!

2 bux a strip is roughly the going rate: http://www.telatemp.com/c/187/110-Labels (minimum quantity 20 labels)

Here you go. You can place these on any thing. The ignition modules, reg/rec, oil tank, coolant or oil radiator, ect.... Any thing you want.
