I wanted to try doing a currrent draw check so I bought a DMM and pulled the negative battery cable. I put my DMM on 10amp scale and hooked up Pos lead to neg post & neg lead to neg cable. My first head scratcher came with the meter itself. It read 13.84? I figured maybe the decimal was moved a place for me. I.E. I was expecting milliamps, decimal to the left etc. (Unfamiliar DMM) Mine is still in storage from the move.
So I proceeded to pull fuses. The only change came when I pulled number 41 (30amp radio, navigation-not installed & on-board diag). The kicker is it went up not down, to about 18.45. I have not pulled the big 50amper ones yet which I believe are like relays? And am wandering if battery is bad. AutoZone checked it said it was good but they did it in the car. Any suggestion appreciated.
