After a couple of hours, my 12volt points motor gray box is opened.
I damaged the top cover slightly at its base along the flange at one corner.
The damage is a flex/cut through the flange caused by too strong of a cut into
the very small gap between the top box flange and the base.
My tool was an exacto-knife. This is a small, thin, triangular/pointed, knife
edge mounted in a pencil-like shaft for a secure hand-hold.
My technique was to wedge the knife edge into the gap between the flange of the
box top and the base. I then made numerous slices along the gap going about
the perimeter of the box. I would also wedge the knife edge into the gap,
settling the full length of the blade into the gap, then rock the blade so as
to gently open the gap. I proceded about the perimeter flexing the blade to
open the gap.
Finally, about at least two hours, the glue gave way, and I have open the box.
Why didn't the motor work?
One of the wires from the solenoid was "broken" at its solder connection to the
plug connector inside the box.
You all are right! It's going to take a steady hand to re-solder that wire to
the plug connector!
Any recommendations on the solder job?
It's too late to try to re-connect the wire. That's good. At least I won't be
tempted to do the job until tomorrow evening.
Thanks for all the help!
Patience, persistence, and a small knife edge were the keys to opening this box
for me.
later,
James Mathis
