Chris was in stop and go traffic just before the Bay Bridge and the temp gauge crept up to hot. He was able to get off the freeway and found the fan was not turning on. The fan relay had gone bad. Luckily he was able to change it out with a spare.
I started to think what if the temp control had gone out. It would have been a breakdown alongside the road and time to call the tow truck.
This weekend we ran an alternative emergency power source (Fused) that will give power to the fan until the switch is turned off. It is strictly an emergency backup. Currently the switch is by the the radiator but I am thinking of relocating it inside the car.
Something I had not considered when I put the circuit together and thought it might help someone else.
Attached is the schematic with the new circuit in green.

I will update the site with the new drawing soon.
