When I put a screwdriver across the two protruding terminals, the starter motor turned the engine.
I reasoned it must be a break in the primary coil windings.
I later checked the wiring and found that I had a resistance reading across these smaller wires, across the solenoid coil winding, meaning the wire had continuity.
I decided to dismantle the unit. It looked great externally, even had a nice red /gold circular decal on the unit.
The result was, the slug and its spring were seized up and could not move. The unit was rusted up inside indicated that it had water in it for a period.
This is for info so that you always make sure you hear a loud click as the soft iron core or slug, moves up to make contact with the two main terminals of the unit.
The unit can easily be checked in your hand by connecting 12v across the small earth and black wires.
