Guardian Angel Fail Safe Question

I have the Cooling Mist WMI w/failsafe lead connected to the Guardian Angel v3. I have validated that the failsafe does properly trigger the GA under unexpected pump duty cycle conditions. The GA worked perfect in those conditions.

But I've had a recent scare (probably near disaster) when I found that for several days, the inline 15 amp fuse to my WMI pump was blown - yet the failsafe was not triggered. Scary to think I was running my WMI tune with no WMI fueling! Winter driving probably saved me.

Question: Does pump power loss usually trigger the Cooling Mist failsafe to the GA? Or is there no way for it to detect this condition?

Hi Andy, so there was 0 current flowing through the pump? Are you powering the controller and pump through separate fuses?

I believe I am. If I recall correctly, the pump is supposed to be on a 15 amp fuse (the one that was blown) and the controller is on a lighter fuse - which was not blown. I'd have to go look to confirm 100%, but I'm pretty sure that is the case.

To avoid any such circumstances power them form the same fuse and it will be clear if such a failure occurs again.
