Coleman 7300 Hard start kit

ok, the numbers on my relay are not the same on the diagram though, does that matter? Should I go by number, or by position on the relay?

Your diagram shows the start kit and it uses the common potential relay numbering. 5-2-1 = common-start-run. Doesn't your relay have 5,2 and 1 on it? If not, you can ohm it and determine the coil and contact terminals. Craig

it has the numbers, they are just in a different position as the picture on my trailer is all.

and Im not sure what that pic shows you posted, I guess I don't fully understand the connections on this thing, sorry.

I know the relay is simple, just not sure what way the power should be going through everything.

And on the new cap, does it matter what side of it is hooked to what? it has no markings on the terminals

Go by the numbers over the position- as long as they are 1 2 and 5.
