I just wanted to check, you specifically mentioned pulling the battery cable
and then went on to say you had no power...
I've got some alligator clips that are super handy for something like this, as
Curley says its hard to get from the key switch to the plug and fumble around
with the leads so I clip everything on so I can see it from the seat when I hit
the key. Does the relay click?
BTW: I re-read your description, neg terminal to the relay, red to the ground
is still backwards. ;)

Thanks Curt.
I know it may appear I'm stupid, I know the battery has to be
hooked up to get 12V from it. ;-) But I have been known to hook a
meter up backwards.
BTW, I also had 12V showing at the large red cable going into the
relay and 12V on both sides of the flat fuse. But with the key on,
there was 0V on the 1 of 5 prongs I tested.
Actually, I believe I had the probes connected correctly but
described it poorly. But I'll check the connection again.
As always I appreciate the help.
