Temp sensors WITHOUT Relais not sure as the Fans suck 10..15 Amps..EACH

The high volume 13 inch Spal fans on my Dennis Quella/Ron Davis radiator each draw up to 23 amps. Jon Haas and Dennis both say they require dedicated number 10 wires directly from the battery and Jon stresses such high amperage fans should not be fed by his ATO fuse panel.

The only current that should be flowing through a radiator thermostat is a grounding connection for the COIL of a properly rated fan power relay.

This is how the original Pantera fan wiring was designed.
