Today I was running power wires for my heater when I suddenly got a highly unexpected 72 volt shock. My ratchet was on a contactor lead and my elbow was touching a chassis bolt.
WHAT??
I thought I had very carefully isolated the traction wiring from the chassis... My multimeter showed a 72V difference between the chassis and traction positive. After a few moments of scratching my head, I decided to unplug the system voltage meter I installed last night and recheck. Once I did, there was no more voltage reading between chassis and traction pos. So my $8 four wire volt meter is not isolated and eventually will have to be chucked for something different.
Or is it something I should even worry about?
