    Electric fan wiring/Aux Fan relays- blowing fuses?

    Has anyone had any issue wiring in an electric fan to their stock Aux High speed relay/wiring and have an issue blowing a fuse only when the fan is engaged and the ignition is turned off?

    Running a SPAL puller, using stock aux fan high relay. I think the fuse/relay gets a power bump when it is engaged and engine is running then the engine shuts off. Basically coming straight off of alternator power.

    I'm thinking of now running a stand alone relay/fuse to the fan and temp switch. This way it will not be dependent on the ignition +12v and will keep running when the car is turned off and hits the 80c thermo switch. Also, this will help since I've noticed that when the fan kicks on for a short period of time and the engine is turned off (coolant temp still =>80c) if you restart the engine it has hesitation since the coolant temp sensor (on thermostat to DME) is saying that coolant temp is too hot to turn on the engine again.

    Just posting here since the "Official Electric Fan wiring" thread is on the swap subform- I don't think many people check it out.

    Is this the ideal way to wire in the fan to stay on after the ignition is killed?
