I’m not good with vehicles but when I parked the work truck, shutoff the engine and pulled the keys out the fan kept blowing what was coming from under the hood. I had to pull the F06 (engine cooling fan #1) fuse from the fuse box under the hood to get it to stop. Now what should I do, I tried re-inserting it a minute later and the fan started up again without the truck on.
I just passed my NICET Level 2 FAS test. I am curious what level 3 is all about?
I have found Quizlet to be a very good study guide. If I can zip through the questions without even looking at the reference books would you say I would be ready for the test?

are the practice tests through nicet worth buying? specifically for fire alarm level 2
Does anyone know if this still works with the cell towers or has it reached end of life? I have been on hold for an hour and tech support dropped the call.
We are converting an existing fire alarm system and I will be replacing 4 duct detectors. I am going from gamewell to Potter. The gamewell detector had a harness disconnect plug coming from the hvac controller. 2 for 24VAC and 2 for the alarm switch. I will now be supplying power from my fire panel 24vdc aux power to the new potter addressable duct detectors, taking away the 24VAC the RTU was supplying. My question is, the 2 wires off the disconnect harness plug that were used on the old detector was on C and NO for fan shutdown. Do I simply take those 2 wires and move them to my duct detector relay C and NO? I didn't know if now taking the 24VAC from the RTU out of the equation if that would mess anything up?
My new ducts need 24vdc aux power, has an slc, remote test switch terminals and 1 built in relay (NC, C, NO)
long story but I have to tie in my fire alarm relay for HVAC shutdown. We are breaking power to the fan @ the thermostat. I am not an HVAC guy but in general NC and C off my relay, remove the positive from the thermostats power and wire this to my common? Then my NC would land where I took the wire off from the thermostat?
