Today I was zapped bt the chassis of a condensing unit. I changed a cc heater on this unit because it shorted out in a puddle of water. I energized this unit after installing the new cc heater and the cond fan grill zapped me. I removed the 24v control wires, so the unit was not running. I put one meter lead on the roof flashing and the other lead on the cond motor grille, the meter showed 260v. I shut down power and removed the cond motor leads. I rechecked for chassis voltage and found none. I ohmed this motor out: c-s 74, c-r 76, s-r 82. I picked up a new motor and installed it with no chassis voltage. I ohmed the new motor before I installed it and the resistances were very similar.
How could a single phase motor ohm out all the same? The motor only uses 2 legs of power. L1 to common, L2 to run cap to run, other side of run cap to start.
