AC Fan low speed bypass

[mrgraphics]

I've searched and searched, and I just can't figure this out. How do you do the bypass so that when the AC switch is pressed, the AC fan only comes on high? I just did a r-143a retrofit, and want max cooling at idle.

Do I simply disconnect each end of the resistor in this picture and wire them together - then replace fuse 19 with a 30A?

Yeah that's how it's done. Though i don't know what amperage fuse to use off the top of my head.

Yep just did this on my track car. I think u just use the same size fuse the high speed circuit is... Don't remember off hand what it is.

If it were me (and it is, I did this), I would jumper the output of the low speed relay to the trigger of the high speed relay so that the high speed circuit gets used rather than the low speed.
