Keep us posted....I have a SPP6 and it didn't help.
The SPP6E worked, I have a spare SPP6 to give away!
I finally got the minor parts and installed the SPP6. Started it on the 20 amp house circuit with no problem{I was able to do this before installing the SPP6}. Started my generator and still the A/C would not stay running but if I start the fan only then switch in the compressor it will run so the SPP6 helped cause I couldn't do that before.
I checked the manual on my gen and while it is rated 4400watts surge and 3500 watts continuous it puts out only 8.3 amps. Not sure what my 13.5 a/c requires but I'll bet it's higher than 8.3 amps.
Anyhow I can get the thing to run so it was worth the effort.
