Alternator question

Heres some more "stuff".
This is with everything hooked up.
Key on, 1.4v to coil +ve.
Key on, 5.6v to cool -ve
Tested "key" side of ballast(blue ign wire and blue w/tracer), got 9.4V(should it be 12v??)
I ohmd the ballast resistor(unplugged) and get 2 ohms.
Just got off midnight shift, I know I forgot some tests. Try to get to them soon.
Thanks all.
Oh lights on, bright hazards and tails all work good BUT, it took a second or 2 for them to "start" if that makes sense?
I also noticed there is no ground strap from engine to firewall. I bought one and would like to mount, where is factory location?
Thanks all, much appreciated.
