Sans Wiggy, I have put a resistor (light bulb on a pig tail) between the same two points and then measure the voltage. The connection to ground tends to "bond" any stray voltage...I think. If it reads 0 volts set up this way, then no worries...if the bulb burns, you have a short. I'm sure the wattage of the bulb comes into play here too for any resisted shorts that would complicate the issue.
I'm asking opinions here rather than suggesting this method. It's sort of a "poor man's" troubleshooting trick, but I'd like to know all the "druthers" involved... Any comments?
