ABS has been reset. I went to the Radio Shack and bought one of the LED #276-0011 and wired up a test lamp. The first time I tried it there was nothing, no light at all. Retested the LED and it was good. So I tried a different grounding point and this time the LED burned continuously, no blinking at all. Hmmm, turned it off, turned it back on and this time both ABS lights were blinking in unison like they should. I can only presume that my previous attempts at resetting were flawed in some way, or as my wife would say, a BOE (boneheaded operator error).
In any event, I have a solution and the ABS is back working. Thanks so much to all on this forum who contribute.
