Icom IC-7000 Manual page 6

to test this modification with an autotuner, such as the LDG Z11 or Z100.
Your Icom 7000 Running Hot? ... Heres the FAN mod!
( This has been untested with an inline tuner )
1. Tuner Lead #3 is +12v DC, tap into Tuner Lead #3 with a wire ( theres enough room
to simply slip a solid copper wire into the crimp for lead #3 )
2. Add a 100ohm Resistor at the other end of the solid copper wire ( a 100ohm pot will
work if you wish to be able to vary the speed of the fan )
3. Strip the insulation of the red wire to the fan back just enough to make a solder
connection to the 100ohm resistor / 100ohm pot. We used a lighter to burn away a
bit of the insulation in the middle of the wire b/t where it connects to the board and
where it connects to the fan itself.
Wrap it all up with some electrical tape to prevent grounding. and Whala! Your Done!!

A 100ohm Pot could be used instead of a resistor, values below the 100ohms will increase
fan speed.
0 resistance - sounds like an airplane.
