Assuming you've checked the connector for corrosion... Peel the boot back on the AMM's connector. Turn the key on to KP-II but don't start the motor. Measure the voltages on the four terminals. Put your voltmeter's negative lead on the battery negative terminal.

The one with the brown/black wire should read near ground, very close to the one with the green/yellow wire.

The orange wire should have battery voltage.

The red/white wire should have a small voltage which will vary upward when you give the accordion hose a squeeze or waft some air toward the front of the AMM. If not, the AMM is not working. Is that K&N something you oil? And aren't these -001 AMMs also used in the 850?

I used to be indecisive. Now, I'm not so sure...
