I am still not having the best of luck staying cool in the coach, but it is getting better.
Long story- but me and generators don't seem to get along. My 6000w onan has a bad field coil. I could not get a ev6010 honda to work for me.
So I went to a 2800 onan microlite, and that one is now not working.
I currently have a ef2200is on the bumper, but even that one quit and spent a month at the dealer getting a new coil pack assembly installed under warrantee.
I am having issues with the ef2200is getting along with the Air conditioners.
I am running an atwood air-command up in the front hole- 15500 btu version with the heat pump. and I have a oem dometic in the back hole.
the OEM one does not get along at all, witch is expected on start up. I did and really do not expect it to run off the yamaha.
the atwood air-command on the other hand I would think it would, and it has always been working great. I have metered it and it usually runs at 7-8 amps, but I do not have a good enough meter to measure the surge, and that seems to be the issue with the yamaha, but only on hot days and not consistant. I can bench test and run it for hours at home, but on the road when it is hot and you need it to work, it has been inconsistent.
I have ran the atwood on honda 2000. and always seemed to work under testing conditions. but I learned that heat and humidity changed the whole equation.
I actually had it running the fan only and the air-command runs, but it will quit turning on the compressor so all you get is fan. I thought my A/C had quit until I switched to shore power and it started blowing cold again.
it is not an all or nothing thing.
So while I am trying to diagnose the true issue with the onan, (part is $300- so I want to make sure that it is bad!!). I am thinking of a hard start capacitor for the atwood. The atwood I thought had one built in, but it is hard to tell in the literature, and if a hard start capacitor would help either way.
I am also going to buy/install one in the dometic, maybe it won't help, but for $30 it can't hurt???
I did dive into the atwood a little yesterday and oiled up the fan motors, and made sure the coils were all clean.
So has anybody had experience? I see some hard start capacitors for like $30. and there is a "micro-air" one that is like $300. the micro-air one I did find someone that did install one on an atwood and was happy with results.
once get my onan 2800 back working, this might not be an issue, but if a hard start compressor makes things work better on the onan 2800, then it is all good. I still hope to be able to utilize the yamaha ef2200is when boondocking and A/C is needed, rather then the onan that is right under the bed.
