radiator fan wiring

You musta saw me turn them on last night while driving...uh yeah it makes my volt gauge drop from 13 to 11.  My blinkers do that too though but even more on the gauge.  Please..what is the fix?

I redrew a factory relay diagram to show what I did.  I am using the stock relays, I just wired them like the pic and took out the thermosensorswhich I erased out of the picture too.

I forgot again, let me try it without a picture,  Radio Shack sells a 4700 microfarad capacitor rated at 35 volts.  It sells for 5.49, it may take 2 of them.  They also sell some 1/2 watt resistors, get a pack of 470 ohm, there are 5 per pack.  Parallel the cap across the coil of the relay.  The cap is polarized.  Ground and positive must be placed on the corresponding connection of the relay's coil.  Parallel 4 of the resistors  and cut the wire that grounds the second relay, the resistors are to be placed in series with this wire.   The way this works is the relay will not energize until the capacitor charges, the resistor limits the current that gets to the cap and relay coil.  More capacitance or more resistance = longer delay.

You may want to mach it up on the bench to test it.  I am thinking that you should be able to get a full second delay by using both capacitors, and 3 4 or all 5 of the resistors.
