Remote Wire Question
#13
As hooking a fan, or any device alike; I strongly recommend NOT using the remote turn on as a power supply. You're lucky if it doesn't damage the deck. The remote turn on was not designed with that in mind.
Typical(12v) fan will use 250mA-1A. The remote turn-on does not have a large current output. By large, probably not more then 500mA.
As for why your deck can handle 2 fans; You got lucky. Obviously current limiting circuity was used, or they designed it with higher current output.
I would recommend contacting the manufacture and ask how much current can be supplied by that connection before testing your luck like that.
There is never a need to use the remote as a supply. You should be using a transistor (to keep things simple) for your fans.
A 2n2222 can putout just under 1A, and takes no more then connecting the remote to the base, battery to the collector, fan (V+) to the emitter.
They're about 50cents each.
