Turns out it was two issues (there was nothing wrong with the starter solenoid and alternator voltage regulator).
First off, the v-belt on the water pump/alternator was worn and popped off. Picked up a new belt and once installed, that's when the initial problem arose (starter engaging intermittently). I order an alternator thinking it's a voltage issue (original charging at 14.66 - takes 30-sec to a minute to get there). While waiting for the part I also suspect the starter alternator so I clean all the connections etc. to no avail (also ordered a new starter).
Again, while waiting for parts, I then decide to check the relay........I replace it..........well as soon as I turn the key on the starter engages and I have to remove the relay to make it stop (the original relay didn't do that, but would start to intermittently engage after a minute or two, but only after the alternator was reconnected).
I start the engine, remove the relay and discover there is still power across the magnet.
Issue one, bad ignition relay.
Issue two, for some reason the previous owner had crossed the BATT and IGN wires
New relay and corrected
wiring, problem solved........at least I now have a spare alternator and starter should I ever need it LOL.
