Motor / capacitor trouble

[hampy_251]

Hello everyone,

Having a bit of trouble. I've got a big Coast spa. Got a screaming deal on it - 8 seater, two 2 stage pumps, etc. etc. It's one from 2003-2004 that had the motor recall (which I'm currently trying to take advantage of with Coast). My problem is this: motor 2 was burning fuses. It would fire up and run just fine or it would buzz before burning a fuse. I left is sit for several months just using pump 1. The other day, I finally got a new capacitor put on and, lo and behold, the motor fired right up (and blew a pound of algae into the water). However, it only runs stage two. Stage one doesn't click, buzz, pop or make any indication that it's attempting to activate. 

So, my question is: is it possible that I plugged the capacitor in backwards or something? I didn't think it's run at all if I mis-wired it.  The replacement is, of course, an exact match for the old one. Or, is the pump simply too old or has been sitting too long? It just surprised me that stage 2 pumped powerfully but stage 1 wont make a sound.
