I also used a switch that glows red when the power is on to the fan and is inline of sight so it is a reminder that the fan is runningÂ when the bike is off. You should be able to hear ir run normally.

Hooper,

I also installed my fan overide switch without a relay. It stays on when I shut off the engine but the fan is loud enough that I have never failed to notice it, even with ear plugs in and helmet on. I don't think running the fan after the engine is off does much good because once the water pump stops turning there is no circulation to the radiator. I have owned cars that were set up to allow the fan to run with the engine off for a few minutes. I usually stood around and waited for the fan to shut off.
