According to that webpage, I was doing it right, but it doesn't tell how to interpret the readings. With the meter dial set to the 10A setting under amps, the red cable plugged into the 10A DC plug port, meter ground wire plugged into common port on the meter I get a reading of 19.xx where the decimal floats a little between .04 and maybe .85 when going from the alternator bracket to the negative post on the battery (it's a side mount but I don't know what else to call it) and the negative battery cable disconnected. I can't find anything that tells what those meter readings mean, I'm guessing based on the value and the amount of arcing I get when touching the meter lead to the alternator bracket, it's the 19 amps but don't know if that's right or not. Car Ground cable disconnected completely from the battery, positive car battery cable hooked up to the battery and the meter negative lead touching the negative battery post. I get one heck of an arc when touching the red meter lead to the alternator bracket engine. I also got a single ding at times like if you open the door with the engine off and the key in the ignition or the lights were still on as soon as you touch the alternator bracket with the meter positive lead. I just checked again, if I go against the upper A arm on the drivers side front, I get 17.xx, I also get arcing if i touch the frame but not off the firewall. Now this may or may not be accurate. I'm partially deaf and at least one time I think I hear something run (like an electrical motor) for 3 or 4 seconds. Reminded me of the sound when the radio antenna extends but fairly sure it was near the firewall and the antenna did not extend. |
