Good Stuff! Most of the talk seems to be about SPP6 and SPP6e. Glad the "5" worked for you!

Yup. The forum is more than just leaning on the back fence gossiping. Many folks want to learn from these posts. 🙂

GOOD NEWS!!! What Make and Model Start Kit did you install!?!? Crowds of us want to know! Thanks for the Update!

Just to touch on my post added a hard start cap. My gen. Now starts my A C

I went with the micro air, I agree they cost more but will worth the money.

Logic suggests that if your generator started one 15K A/C it should start another that's configured the same way.
The ultimate "start" is Micro Air. Below that, there are Start Kits - Capacitors controlled with PTCR, Potential Relay, or Electronic Switching.
I'd try $10-$50 on a Start Kit before $300 on Micro Air or $3000 on a new Generator.
But I gotta ask:
1. Do you know if your old A/C had a Start Kit and the new A/C doesn't?
2. Does your new Camper have so many more Bells and Whistles, that your generator's output is being soaked up by loads it didn't have before?

I think you need a bigger generator.

[MrWizard]

yes but the new is the new one larger cooling capacity
was the old one a 13.5 or 11.5 ?
makes a big difference in the startup load

2800 Yamaha the reason I did not give this info on generator was did not want to start the same old thing , need bigger generator, etc ,. It started the old a c fine will not start new all the time
