Re: ground isolation on VRM and PCM
No voltmeter (DVM or Analog) will short if its used to measure voltage between two points (by plugging the probes into right sockets on meter or turning the knob/dial to V, depending on the meter). Its the ammeter that is used to measure current in a circuit has very very low resistance and will short circuit when used to measure the potential difference between two points.
