Horn blows

If I installed it under the back seat I would not be able to observe the lights on it or take the voltage readings without unlocking the truck and opening the back door which will activate things that will reduce the battery voltage reading by 0.1+0.3 volts. I connect it to the jump posts with the hood up allowing me to get the reading. If the noco is still plugged in the door opening will cause a reduction in the battery reading which will start the noco charge routine. With the hood up the noco ground clip can be removed leaving the jump pins to reveal the 12v battery without active draw reducing the actual reading. You can then take jump pin multiple reading of the 12 volt over several days without disturbing the soc of the battery. If you have meter capable of accuracy in hundredths of a volt you can track battery soc over a week or more if you leave noco unattached. Also rumor has it that mice are less prone to chew wires if hood is up.

If you leave the hood open I wonder how much power is used by the hood open sensor.

If you leave the hood open I wonder how much power is used by the hood open sensor.

I would have to put noco clamp wires under hood to jump pins then test battey with them hooked either to Noco or voltage tester. My tester with resolution only showing accuracy to tenths of volts will show max of 12.9v with hood up immediately afer removing noco slowly dropping to around 12.6 in a week. Then after driving and not using noco the ~40 month OEM 12v settles at 12.4v (taken at cig power point so is subject to the busy buss of 0.1-0.3v drop). This is on my low usage xlt with luxury pkg 6800 miles. May see if I can find out sensor usage with hood up using wires from outside grill to jump pins or to battery pos post and negative body ground.
