No I haven't. Manual says 20mA with key on, ignition off. Reading should fluctuate at idle speed and operating temp. 2 to 6mA with simulated 20c, and O2 sensor unplugged but of course I don't have the 2.5k OHM test cable so I'll have to skip this test. Are there other readings to test?
If so, point me please to the post you refer to Stephen.
