THe Supco SPP "softstart" kit is not much more than an circuit board and a
capacitor. My preference is the Kickstart TO-5. It is a true hard start kit
with potential relay and start cap. I have had to replace several SPPs but
never had to replace a Kickstart.
My 2 cents

It sounds like you gave Jake a jump start on the kick start!

A agree, but I still like to use the correct start relay and capacitor over
all of these start kits.
My 2 cents.

I really prefer the real start kits from the olden days also. Totally
argee about Supco and other "start boosters" or whatever they want to
call the POS's. We have been using Kickstarts for quite a while
although we do keep Trane start kits in stock at the shop. Overall, I
guess the Kickstarts have been OK. I have seen a few fail, but
considering the number we use, really not that bad. Noon and others
using them, do you use the TO5 on all units, or do you also use the KS1
on 3.5-5 ton? AFAIK, the only difference is the start cap is a little
bigger on the KS1. FWIW, I have an old air compressor with a 230 volt
belt drive motor (called 5 hp but probably actually 1.5 max) It has a
run cap and a centrifugal start swich. The centrifugal switch would act
up about every other start. Dunno if the points are bad or the mechanism
binding, but I put a TO5 acoss the run cap years ago and it hasn't
missed a lick since. Larry

Jake, did that unit have a solid state time delay relay on it? I have
seen them go bad and cause a contactor to chatter. Saw one on a Rheen or
Ruud a few years ago that completely fried a brand new contactor in a
day. When in doubt, replace it-- they cost next to nothing. Larry
