Hi Larry,
If the battery is disconnected 0V is what you'd expect, also you've got the
meter hooked up backward. Red is ALWAYS +, black is always -. Either you were
holding the probes backwards or they're in the meter backward...

Well, add this to the bizarre file. I started typing this reply and it
disappeared. Poof!
Oh well, I guess that was practice. The doors were locked some how and
the alarm went off without any warning! Man! That's scary when the horn
sounds and the lights flash! Naturally I had left my keys
upstairs! So I pulled the + battery terminal.
anyway, I thought I should follow someones instructions to test the 5
pins coming from the relay. I put the Neg Probe to 1 of the 5 pins,
then I put the red probe to a ground such as the manifold. It read 0 V,
with the key turned to the pre-glow position.. That didn't sound right.
So I need to decide what to do next. Might have to buy my wife a car...

Seems reasonably good, now find the fault in the wiring from the plugs to the
relay...
