Mark,
OK more confusing advice. Solder the thermostatic sensor to a radiator drain
cock. Them install in the current drain position as this will prevent tube
scuffing/leakage (providing of course that it still works after soldering).
Get a good 12V relay to handle the current of the fan and an ON/OFF/ON
toggle switch. Now for the setup to cover all bases. Wire one side of the
toggle ON to the ignition then to the fan solenoid. This will allow the fan
to go off when the car is off (an advantage on a cold day or when working
under the hood --- without the engine running). The current draw of the
relay activation should be low enough not to affect the ignition. Wire the
other side of the toggle ON directly to the starter solenoid then to the fan
solenoid. This will allow you to have cooling in hot weather even with the
power off. This can be helpful if you start and stop alot on a very hot day.
This way you will have a choice of cooling methods to work to your advantage
as needed. Your fan current draw will come directly from the battery (do use
a fuse though) and not overload the Tiger wiring. I would recommend that you
do put a warning label about the fan possibly coming on at anytime. You
never know who might be working on your car and what position the switch
might accidentally be put in. Finally, for (short moments) while working on
the car while running the OFF position will allow the safety of not having
the fan come on when your hands could be in jeopardy. Just always remember
to have the toggle in the right place at the right time!!!
