Connect ground wire to ground. Connect positive wire to the same positive wire as the amp is. If you lost the charging resistor then connect the wire to the cap first then connect to the power source. This will keep it from sparking and damaging the plating on the connector.
On the top of the Capacitor if you look closely H(Compressor) C(Common) & F(Fan) will be stamped on top of capacitor. You will have to follow the wires back, my guess is blue could be the compressor, yellow probably the fan and brown the common. the to yellow wires are probably hooked to each other and can be changed if the motor starts up the wrong way. Follow the wires back to each component to double check
On this unit wiring is very basic, line in wires to the two lugs on the bottom, common as refered to is always black wire which goes to the compressor and the fan motor, red to adjacent lug of the contactor which then one goes to the capacitor and one to the compressor and one to the outdoor fan motor. One wire usually yellow from capacitor to start winding of compressor marked on the capacitor as herm, and a brown wire to the fan motor from the capacitor. The side connectors as you know go to the 24v control coil. The reason as to the fuse going out could be due to loose connections in the disconnect box or a short in the wiring at the compressor, fan motor or capacitor, and worst case a shorted compressor internally. Recommend having the system checked with the proper equipment to include an ohm meter with uf reading ability.
Well, I have no idea why you would have two capacitors on a 500 watt amp but, did you charge the capacitors? Have you tried the amp without the capacitors? What size power wire are you using?
You hook it up in parallel with your amp. You'll see a and - on the clear plastic cover.
Hook a wire from your amp or positive to the capacitor
Hook another wire from your amp - or negative to the - on the capacitor.
That's it, you're done.
If the plastic cover is missing, or painted over, with the neon tubes at the top, and the connector/display end facing you, the right side is the left side is -.
OK, locate the terminals on the capacitor marked "HERM"(Compressor lead), "FAN", and "COM".(common)
HERM and COM remian as they are.
The wire going to "FAN" (usually brown) will be placed on either terminal of the new capacitor. (This is the ((usually brown)) wire comming off of the fan motor.) An additional wire needs to be run from the other terminal of the new capacitor to the "COM" on the old capacior.
What you are doing is bypassing the fan side of the old capacitor but still using the compressor side of the old Cap.
The fan should have a wiring diagram on it to help identify the wires if there is no brown wire. The other two wires will be identified on the wiring diagram as well, but one typically goes to the contactor and the other to the board.
When hooking up capacitor on a pump it doesnt really matter which way the wires go. The capacitor is set up in such a way the it supplys power wherever the wires are hooked up. I hope this helps
