CB radio mic turns on EFan
« on: October 19, 2012, 03:43:42 PM »
Hey guys here is a weird one. I have a DCC Taurus Efan controller that is wired directly to the battery (positive and neg.). I also have a blue sea fuse block that is wired directly to the battery (pos. only) via 4g with a 60amp inline fuse. The Cobra 29 is wired directly to the fuse block. The CB radio is mounted overhead to the roll cage. The DCC controller uses a temp sensor to only turn on at a certain temp, unless the AC is being used and it give the fan 50% power.

Whenever I hold in the mic button on the CB radio, the Efan will turn on, if it wasent allready on. I also have a set of HID hella's wired to the fuse block and there is no interferance with the fan if I turn the lights on. Anyone have an idea on how to fix this little issue?

 Ya I considered this but the fuse block recommends no bigger then a 30amp fuse and a I have a 50amp inline for the fan.

I just looked up the fan unit...seems to be a pretty complex wiring for the DCC unit.  The only thing I can figure is that somehow the RF from your CB is triggering a relay in the system?

Or...the RF is traveling through the power cord to the battery...which is even weirder.  ???

Ya that is my conclusion also because it does not happen when the antenna isnt mounted.

Okay, did a little reading.  

Start by wiring the CB directly to the battery, not through the fuse block.  A clean power source is key.

Also, keep all wiring for the CB, power and antenna coax, away from other electrical wiring/power sources.

 is the fan turning on the 50% setting or full on? does the power wire for the cb run next to the fan wiring?
