Countax Posted October 6, 2007 Share Posted October 6, 2007 Can anyone pls advise the location of the common earth connection for a P38a heated front screen. My screen is measuring 25 ohms to earth which means its pumping out a whopping 5.7 watts of heat per side ! I have a similar problem with both door mirrors. One heater is at 9.4k ohms so is producing 15 milliwatts, the other is 8 milliwatts!.....is it a common problem for door mirror heaters to fail high resistance?
