Re: condenser
I use a digital meter on the highest, in my case, 20 megohm resistance setting.
Make sure the condenser is not in circuit with anything else.
Apply the test leads to the condenser, usually to the case and the one lead or terminal that it has.
Don't have a finger on each of the leads or you will introduce your own resistance into the circuit.
You should get either no reading, or, more usually a "kick" of a reading - say 5 megohm - which steadily decreases to zero.
Reverse the connections. You should get a bigger "kick" which again reduces to zero.
Any reading above zero means the condenser is scrap.
I don't think this guarantees the condenser is good, but it does tell you if it is definitely bad.
No kick either way probably means it is open circuit, and , again, scrap.
