AC hard start capacitor

I'm looking to hook up a hard start capacitor, but having trouble figuring out which one I need. I have a Coleman Model # 48254C869. Can anyone point me in the right direction?

Supco HS6 (SPP6) Hard Start Capacitor would be the one to get.

Yep. Me too- same one. FWIW I even keep an extra one in case another camper needs help.

Fantastic, thanks for the advice and especially the tutorial. It sounds like this capacitor is pretty generic as a one size fits (most) all solution. My champion 3100 will start the AC so long as I turn everything off first which is a pain. So I figure a little help from the additional kick will increase it's overall life. Now the trick will be to know which is the run capacitor. I think the manual has the diagram.

When I took off the cover to the AC, the electrical drawing was on the inside of the cover... no guess work.

I run a 2011 13.5 with a WH2000i with no problem. Works great.
Hello Thomas,

Thank you for your inquiry and your interest in our EasyStart products. EasyStart is perfectly suited for your Coleman Mach 13.5k system powered by a Honda EU2000i. In fact, we’ve done extensive testing with the Honda EU2000i generator, and we know that it will start any 115V air conditioner on the market from ECO mode. That will be key for your being able to run overnight on one tank of gas.

The model EasyStart that you need is ASY-364-X36. You can view it on our website at this link, and purchase it in our webstore at this link. There are generic wiring diagrams on our website, but we can assist you further with your specific system. If you send a photo of your wiring diagram, we can edit it and show you exactly where the EasyStart connects.

To help you figure out the wiring on your own if you would rather do that, it turns out Coleman-Mach manufactured a 15k rooftop system specifically meant for applications in Australia, and they built in EasyStart in their factory in Kansas. Attached is a wiring diagram of that system which shows the EasyStart’s 4-wire connections.

Please let us know if you have any further questions. Thank you again for your interest and business.

Would like to see a little more detail for install as I'm not an electrician. Later RJD

Sorry aceinspp...

I will attempt to explain more fully.

CAPacitors are large round metallic cylinders or sometimes shaped like a racetrack (almost oval shaped) about the size around of a Red Bull can or a little smaller and not as tall. There are usually 2 or 3 of these CAPs and they all have wires installed via electrical metal tabs on the tops that allow a mating connector to slide on and off to make a solid electrical connection. The top part of the first pic shows a round silvery object which is a CAP.

Please make sure your RV is NOT plugged into any AC power when doing this connection.

In the bottom part of the first pic you see the diagram found on the AC cover to help IDENTIFY the START CAP... in this case I can see that only Yellow wires run to the START CAP, while another CAPacitor has Yellow, White and Red wires running to it, which is the RUN CAP, which is NOT the correct CAP for this install, or the FAN CAP which has brown/white and brown wires running to it.

The second pic shows the SPP6 you will get and the wires coming off it that need to be connected to the START CAP. These mating connectors will slide onto metal tabs already present on the START CAP. It does not matter which wire goes to which metal tab on the START CAP.

I got my SPP6 from amazon
http://www.amazon.com/Supco-Relay-St...ustomerReviews

Use a pliers tool that allows a firm grip on the metal connector of the SPP6 wire and slide both of the wires into place on 2 different top sections of the RUN CAP. Those two sections will be very apparent when you look at the top of the CAP.

After you open your rooftop AC unit, look at your diagram on the cover and ID the color of the wires going to YOUR START CAP. Chances are they will be the same Yellow wires as mine, but double check, then look at these instructions again to verify you have ID'd the correct CAP (START CAP). At first I did not have my SPP6 installed on the correct CAP, and my AC fan did not run correctly, until I took off the SPP6, then all was fine again.

I hope this helps explain the install process a little better...

Finally got the SPP6 in the mail and want to be absolutely sure about wiring it in. Have identified that the correct capacitor is the round one with a red wire on one side and a yellow and white wire on the other side. Appears the Supco wire with the extra tab sticking off to the side is to be clipped to the side with the RED wire - correct? (There is some conflicting info about it on YouTube videos I've watched.)

Motor starting capacitors are non-polarized, AC devices. It doesn't matter which wire you connect to the red and yellow wires as long as you are connected to the two connectors on the START cap... in my install the START cap was the round one and not the oval one...

To be perfectly clear... there is no + or - (polarity) on the new hard start cap, so whichever way it connects easiest is OK.

The larger is a run capacitor for the compressor and the smaller is a run capacitor for the fan.

All right then, I'm set to go. Will be awhile before I'll be checking it with the generator and will post the results. Thanks again.

Keep in mind capacitors store quite a large charge and you could get a "charge" out of one.
Don't short them out, it could hurt.
