Default Condensers

Is there a way to test condensers? I got these recently, but don't know if they're any good. Thanks for the insight.

If you don't have time to do it right the 1st time, how do you have time to do it the 2nd time?

My Fluke 87 DMM has a setting to to test the value (microfarads) of a condensor, but doesn't tell if they are good or not.

They are not going to be reliable. Do not use them unless you like replacing them on the road.

From experience. Back 40 years ago I was testing all sorts of 'new' old condensers for the A. They would always fail eventually.

The best tester is the coil condenser tester. They will warm it up and show a fail state quickly.

Do NOT even think for a moment the capacity tester (size of the condenser) on a meter is going to tell you if the unit is dead. It is rare a bad condenser shows the wrong value. They fail because the separator has 'dried' out or changed its chemical properties. This changes their resistance (in simple terms) in use and allows leakage.

Your best best is a quality burn out proof condenser.
