Yes when it shows 1 that means open or no continuity.  Closed (plunger in) should be zero.  Seems to be working.

 Thanks again, now it's onto the brake bleeding to get it back in position.   Fingers crossed

Finally got time to finish bleeding the brakes, to reposition the pin in the distribution block. I loosened the right rear bleeder while my wife gave easy brake pedal pressure and the safety light went out! I found that a slow stream of brake fluid seeping from the wheel cylinder was just enough pressure to reposition the pin. Hopefully this thread will help others as it did for me. Thanks to all who helped out along the way!!

+2 NPD has them, I made my own.

For the home hobbyists who don't wish to wait on or buy the brake warning light bleeding tool, an 1/8" x 1/8" rivet and a standard 3/8" inverted flare nut make for a cheap and easy to come up with ideal substitute.

Also you won't get a valve centered by bleeding it. I used an NOS unit I could move the shuttle valve easily with a pick before installation. I hadn't put the lock tool in it and my assistant stuck her foot on the pedal. The bias was to the front so I put a towel under the master and removed the brake line from the front of the master to the distribution block. Looked via the hole in the flair. You'll see the silver shuttle valve.  Push it back centered with the pick, lock it. Reinstall the brake line and start from the left rear, right rear, right front and left front.  Put the switch back in and you should be good to go! Best of luck to you!
