Re: multimeter question

Always use the negative cable. The draw test will work with either cable/post. There is less chance of shorting things out on the negative side. When you disconnect a battery disconnect the negative first and hook it up last to avoid shorting. Batteries give off hydrogen gas & can explode when a spark is applied. I suggest using the test described in your volt meter's manual because they differ. I noticed your meter's milliamp is separate from your amp. The better meters have a low amp and a higher amp jack. The easiest way for a "newbe" is to hook a test light with a real 12v bulb across the disconnected neg. batt post to the cable. If your truck has onboard computers jump the bulb connection with a jumper wire for 15 minutes to allow the computers to go asleep then remove the jumper and bulb should be off. Examine the bulb closely because it could be on very dimly.
