Re: lawn sprinkler control unit repair
So I will be cheching the colored wires to the common while they are
not connected to anything on either end?
What resisitance does a piece of wire show if it's good. Probably
depends on gauge but the wires I am dealing with are fairly small.
Braided but looks not much bigger than bell wire
