My understanding of basic electricity is limited, which leads to the following.
I have a squirrel cage blower on my furnace. The motor won't start the blower, but a little push will allow it to start and run. Since I know a little about electricity, and can look things up on the internet, I've determined the capacitor is not working.
When I removed the capacitor, I found no indication of any polarity, or special marking to indicate the correct connection of the wiring. Since the capacitor doesn't have any markings, and I had to remove the capacitor to find a replacement, I've reached a quandary.
What is the next step, when I find the replacement capacitor. The capacitor is removed, and if the new one has special markings, how do I determine the correct connection, which involves only two wires. Do I check to see which lead has voltage present, when the breaker is on? Do I avoid this, and check for which lead is grounded? I'm confused and need some help.
update: Further research shows an alternating current capacitor in the application doesn't have polarity.
