Hard Start for AC
Installed a Supco SPP6 hard start kit on my 2007 Coleman Mach 15000 btu AC and it didn't work, it actually did just the opposite. I overload my generator, voltage dropped to 50, not good, without the ...

It'd be good if you posted the full model number of the Mach 15, and a picture of the capacitor area.
On our 2002 Mach 15, a Start Kit was apparently a factory option and Jayco got it that way. Has a Relay-controlled Start Assist. RVP now says their current model Mach 15 is standard with hard start, but they use a PTCR device in place of the relay. If there's already a start kit, you can't add one on top of it.
The SUPCO SPP6 uses PTCR. The SPP6e is "electroncically controlled" and is supposed to be equivalent to an OEM Relay setup.
Here's where it gets interesting. Chris Bryant, one of our resident service tech gurus, recommends SPP6e. SUPCO recommends SPP6, and I found their explanation of why. Their tech says the "e" series will take the start assist capacitor (usually round black plastic case, 88-108 mfd) out of circuit too quickly. Not giving the generator time to react to the starting load of the A/C. That's SUPCO's position.
