Man I am going to check mine tomorrow. If that is it it would be great. Thanks for the info.
Man im just stumped maybe im not using the voltmeter right but im sure i am....i set it in COM for the neg and the one for measuring mA. switch to DCmA where the meter reads 0.00 and thats it...
To test amp draws with a VOM you need to have the meter in line with the system. So you would have to disconnect one of the wires or battery cables depending on where you are testing at and put one lead on the wire and the other lead were you disconnected the wire from. That is why you are getting no reading. The only way to test without putting a meter in line is to get a clamp on amp meter that reads DC current.this voltmeter is 200mA max so could it be maxin out right away so i wouldnt know??
Take the red lead and connect to negative post and the black lead to the negative battery cable, you don't have any voltage the way you are connecting it now. So you will not get any current draw. Also you if you are still not getting a reading, check the fuses in the meter, they may be bad.i disconnected both negative terminals from the batts. then hooked pos to the red lead on voltmeter that says 200mA MAX and then neg battery cable to the COM
Slow down. Do you realize that there is a significant delay after start before the alternator kicks in? :drinkthese batts were at 10Volts when i turned the truck on tonigt... and the lift pump bogged a bit before turnin over the truck.... third the batts are charged i think now cause the voltmeter on truck display is reading 14 now instead of 10 as its runnin outside as we speak so alternator must be working....
