I rewired our C152 outlet to the voltage converters output. Even though
the Lowrance Airmap 1000 supports upto 28v input. We didn't have the
dropping resistor, input to the outlet was 24v...

I'm admitting that I'm not the world's best when it comes to those
electrons, all running around helter skelter, but I thought a dropping
resistor only worked with a certain sized (constant) load. If you checked
voltage at the plug with a volt meter, you would come out with 24 volts; if
you checked it with the lighter going, you would come up with 12 volts.
Right?

That being the case, you have to use a converter, or a regulator, or
something. I don't know. Anybody?
