Meaning they have a positive and negative pin. The pin which is long is the positive pin and the pin which is short is the negative pin. You can also identify the polarity using the negative strip on the capacitor label. As shown in the picture above the negative pin will be directly under the negative symbol.
While using an Electrolytic capacitor care should always be taken to connect the positive pin to the positive of the circuit and the negative pin to the negative of the circuit. Also the voltage appearing across the capacitor terminals should always be less than the rated capacitor voltage (V).
The Electrolytic Capacitors have polarity. Meaning they have a positive and negative pin. The pin which is long is the positive pin and the pin which is short is the negative pin. You can also identify the polarity using the negative strip on the capacitor label.
The value of a ceramic capacitance will not be directly mentioned on the capacitor. There will always be a three digit number followed by a variable; let’s learn how to identify the value using these numbers. Consider the following capacitor. As you can notice, these three digits are split into two digits and the third one is the multiplier.
These are also polarity sensitive. The positive lead is often marked by a + sign adjacent to it. Values are normally marked on the side. Other types of capacitors available include: ceramic, polystyrene, polyester, polypropylene and mylar. None of these types are polarity sensitive, and can be connected in either orientation.
The capacitor polarity is designated by the ' + ' symbol on one of the capacitor pins, meaning that the higher voltage should be connected there. What is even more interesting is that there are capacitors in which you can adjust to change the capacitance value. It is called a variable capacitor. Here are how the symbols are typically drawn:

Probably. Basic measurements would be continuity between pins, continuity to case, confirm that capacitance exists and to confirm +/- polarity, charging it both ways from a higher voltage supply, say 50/60V through, say, a 4k7 or 10k resistor. proper polarity will charge to near 35 V; reverse will stop at a low value,say 3 to 5 V or so. I bet ESR will be very poor.
