Tyre Warmer Pin Resistance
I got given a pair of unmarked wrap around warmers and I'd like to know if they fit on other tyre warmers without just plugging them in and potentially releasing smoke.
The pic shows the resistance of the circuits. The 11k ohm circuit resistance drops as temp goes up. My measurements were taken at around 20deg C (68deg F).
Help would be appreciated.

My Muchmore cups are about 7.5 Ohm (nearly an order of magnitude less than yours) for the heater circuit (same pins though). The thermistor resistance is very similar.
I bet if you plugged those into my CTX, they would not get warm (if the 70 Ohm figure is correct) - at 12V, they're at the 2W mark.

I just rechecked the heater circuit and I got 7 Ohm this time after reading the multimeter properly.
Thanks for your help.
