Alrighty gents...my problem is no power getting thru my start/ ignition switch on my column. Here's what I know:
All new harnesses in the column with a new switch
12v at the large red lead from the dash harness to the column harness.
12v making it thru the .connector at the bottom of the column and presumably up to the switch.
Put the key to START and no trigger voltage at the starter post....hence no cranking.
What am I doing wrong or what should I be testing next??
 
Check the connector at the bottom of the column. Sometimes the electrical lugs are not correctly locked & get pushed out of position....& no contact.
 
You said, "12v making it thru the .connector at the bottom of the column and presumably up to the switch." Check the lead from the switch to the lug on the firewall.
 
You wrote starter post.
The next place to check is the starter relay.
It may just be the neutral safety switch
 
Circuit; Battery + to ignition switch. Then power out on the yellow wire thru the bulkhead to the starter relay. The relay has battery + on the large stud. The black wire in the corner of the starter relay is grounded at the neutral safety switch when the shifter is in N or P. The brown wire on the small stud feeds the starter solenoid. The starter large stud is fed from battery +. The starter relay feeds battery + from the large stud (red wire) to the small stud (brown wire). When the key trigger signal (yellow wire) is energised and grounded thru the neutral switch (black wire) closing the internal contacts in the relay.
