Hi all. I am having a problem try to measure the amps to my cell. I have to different amp meters. One is wired into teh car which i wanted to use on a permant basis. It is 100Amp DC meter. when i hook it up to the cell (using the shunt) it will max out the meter almost instantly. And yes i do have a PWM and no matter what setting i have it on i run into this issue with the amp meter.( and yes the PWM is functioning properly). The other Amp meter i have is a craftsman mutli meter with the capabilities of reading up to 20 amp both AC and DC, but again when i hook it up to the cell i can hear the PWM straining and the meter almost instantly maxes out. Any info to help me out would be greatly appriciated. If you need any more info to help diagnose my problem please ask. And THANKS in advance.
