Good info. Were you having issues starting it with a generator? ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

Interesting (tho, unfortunately, I don't know beans about things electrical). By "hard start cap", I'm guessing you're referring to a capacitor, yes? So, questions come to mind. Like, how do you know if you need one? What problem is it solving? Could everyone (with an A/C) use a mod like this? Thanks in advance. ------------- John & Teri Tundra 5.7L V8 / RP 180 E2 WDH / Integrated controller (POS) replaced by Tekonsha P3 |

It gives a little more boost to the "starting load" of the a/c compressor, for some, it will allow an underrated generator to start the a/c. Running it isn't usually an issue, just getting past the surge load need at start up is.

| Yep i was having issues getting my generator to start my ac compressor, unfortunately the cap wasnt quite enough to fix the issue but it definatly helped. |

Thanks all .. Very informative discussion. Ditto on the link to modmyrv (http://www.modmyrv.com/2009/05/27/rv-air-conditioner-hard-start-capacitor) This looks like a really useful mod to keep in mind if hard starts, especially with a gen, ever become a problem. Thanks again. ------------- John & Teri Tundra 5.7L V8 / RP 180 E2 WDH / Integrated controller (POS) replaced by Tekonsha P3 |
