Here is where the charts are: Hi Earl, testing a cross the fuse shows a 1.7 mv drop from one side to the other. This tells me there is still current running through the circuit, even though the truck is off. Enough to drain the battery over several days sitting. that reading should be 0.0mv when the truck is sitting off. I tried a new fuse. It did not change the parasitic draw. A 1.7mv drop on a fused, 10A circuit is the equivalent of about 220-230mA, according to Ohms law, probably. Thanks! any other ideas?

Testing for parasitic draw with test light connected to positive side. Test light is on and truck was off all night. Battery is 12.78V. The circuit shows 1.5-1.7v drop across the fuse. Charted out it was a 200-230ma draw down on the battery. When I pull the 10A fuse for ICP/DIC, test light begins pulsing, it doesn’t go off it pulses from bright to dull with regular frequency. How can current be passing through a circuit when the fuse is not present?!?!
