On some HVAC units, the blower wires connect to the back of the transformer (on older units). For this set-up and a few others, it is somewhat time consuming to test the voltage going to the blower.
I wanted to use an ammeter to see if the blower is receiving volts. My thought is that if the blower is trying to start, I should receive a reading on my ammeter. How much of a reading would I get on a 1/3 (120 or 240 volts) blower reading if the blower was trying to start? I would use it on the positive wire and not wrap it around the ammeter. At least, this would give me a faster start in some situations.
