Here we have a way too big start capacitor PLUS a hard start kit.

The previous HVAC Dr. has done some hacking... one cap tube blocked off, the other merged into this...

and on the other side...

an expansion valve and monster-size compressor! With insulator hat missing on top!

I googled the model number of the compressor and found it is rated at 15k btu! Running off 110VAC!! Is this possible?
It used to go in a (pre-2003) Dometic RV rooftop a/c unit rated at 1530 running watts and 15K btu cooling... the manual says use at least a 3500 watt generator (so it can start) and 12 AWG power wires! WOW. It says use a 20 Amp breaker.
The txv in this unit was rated at a whopping .75 ton!
Now I think I know why the 1 cap tube was spliced in and the other one crimped off. Follow me here... .75 ton = 9000 btu.
1/2 of 12000 btu worth of cap tubes = 6000 btu.
SO....
3/4 ton worth of txv plus a 1/2 ton worth of cap tube = 1 1/4 ton = 15000 BTU???
Bobby Joe's Appliance Repair done gave grandma her money's worth, didn't he?
I never would have guessed this would work!
Ima gonna hafta ask granny about that. Wow.
