In a single phase (common residential A/C) compressor you can verify with an ohmmeter whether or not the A/C compressor is bad. And if there's a single cap with just 2 wires yes that sound like a starter - else if it included run there'd be a 3rd terminal on the cap and there'd be 3 wires. L1 and l2 are designated as the two connection points representing the two electricity flow path inherent with single phase circuits where a single phase supply voltage is fed to the motors internal circuit.

If you're converting to using separate start and run capacitors then you will simply use that original COM wire to feed separate Start (previously the S wire) and Run (previously the R wire) capacitors. Hold the base of
how do I find the correct wires for starting and running caps? But there are steps that can help sort out which wires go where.Next time, remember to tag each wire with an ID and write down its connections before removing wires from their connections on electrical equipment.Watch out: It's safest to take a look at the wiring diagram on the equipment itself - you can follow them to the marked-terminals on your start or run capacitor.
