Just a caution, a check of voltage or resistance is only a part of the puzzle. If the connection(s) on one or both ends are corroded, it may still pass a small amount of current to show voltage but may not pass enough current to support the user, i.e. pump or starter, etc.
Connections must be clean to pass current. Dennis C.
