Do you mean a bump cord?
A switch that would put 120 volts directly to the compressor?
We used to make them in school for small domestic refrigeration stuff.

If you wire it that way,YOU WILL PUT YOUR EYE OUT!! I would recommend a good meter,and amp clamp to test with.

I would recomend a lot more basic understanding. Put the tools down Pick up the books.

it was a test question and I found it in modern refrigeration and a/c book but in modern refrig. it shows 4 leads and the test only used 3,common run and start.maybe I should contact them and tell them that they are stupid and their information is not correct?or do I merely suggest that they need to get their information correct before they put it in a study manual I had no tools in my hand only a book

Maybe you should have included that information in your original post because I thought the same as the others when I read it. Post the edition of Modern Refrigeration and the page number and maybe one of us can take a look and get a better idea of what you are asking.

the way I posted was probably wrongbut I had never even heard of one and thought that the pro's here would laugh and know exactly what I was talking aboutas I wouldn't think they are that common but that is why I posted in tools and test equipment.I was using the 18th edition and found test cords on pages 428,429,430.on my test they leave only 3 leads for answers,common, start,run.and yes I am smart enough to know to only energise the start momentarily.I would think that a masters test would give all info. and not use something as dangerous as a test cordthat is close to a suicide cord in my opinion as the one they sell to provide a 120v outlet on a 240v source(although I cannot say I haven't used one or don't have one on the truck!)

thanks anyhow---jack

The original idea was to connect a "Capacitor"

Black-Common
White-Run
Green-Start through a "Capacitor"
also should have a "Momentary-Switch" N/O

thanks icehouseI greatly appreciate your help

the forth wire your instructor is thinking of is a chasis ground near the compressor . that is you green wire. and is printed in the hvac books at times. they wrote it that way just for safety measures. theres a permanant split capacitor type that uses a start capacitor wired diferent than some start systems. in any regards you should be able to use a start kit 3 in 1 and remove existing starter relays.. especially on a small frige system under 1 hp.
if you do a search on the internet you can see the wire diagrams for psc and other types of motors. I too have recently started on the hvac. can allways start small , fridges , then ice machines, then walk ins. roof tops electronics is my next step up.

i seen some in the late 80's. used to unlock commpreessors kind dangerous

How so ? I've done this many times. Also my "Annie A-12" is set up with a reversing switch.
