Hello Folks,
I wire a 300 amp 50 mv shunt into my fully charged E-20 tractor today.
I made some notes as to the current at the shunt as read in mv and compared
them to the colorings on the meter.
I did not mearsure the pack voltage but it was freshly charged. The pack
is
6 trojan 220 amp hours approx 3 seasons of
mowing and snow blowing on them
I am assuming that if I multiply mv X 6 I will get amps of current using
this shunt. Please if I am wrong some one correct me
1) On the "low scale" 1/3 green showed up as 4 mv or 24 amps.
This is the current consumed by the mower with it running but not cutting
grass
2) On the "low scale" The line between the green and the yellow was 12.6
mv or 75 Amps
3) The line between the Yellow and the Red was 20.2 mv or 121.6 amps
4) The end of the Red on the meter scale was 26 mv or 156 amps
5) The meter pinned right to the end was 55 mv or 330 amps
I was not able to read the battery voltage at any of these current levels
Any comments appreciated
