I'd be interested in the answer when you figure it out.
 
Are you just going with a hot prop or are you going to try the thermawing?

Subject: [LML] Prop De-ice Failure Warning

I have a 4 blade MT prop with de-ice boots on my IV-P.  I have not confirmed the current draw but for this discussion lets say each boot pulls 5 amps at 24 volts.  So if all 4 blades were on and working, the total current draw would be 20 amps.  I would like to obtain an electronic device that would measure the current draw and trigger a warning light and thus a voice warning in my Master Warning System Display if the de-ice switch was on and the current draw was less than 18 amps.  The goal is to prevent one blade from tuning into a frozen stump and causing a big prop imbalance.  Please help this electronically challenged mechanical engineer.
