If i test between pins 5 and 7 with this card pulled i should get a reading Mohm range correct?
I hope i remembering this correctly from the tuturioral, out of curcuit should read in the Mohm range
I get 4.17k on every one. And what is the value or part number of CL1-CL4? If these capacitors fail if the ic fails.

Lift pin 7 and re-check.
The value varies. 4.7uF - 10uF. Measure the ones on your board to see what the average is.

Perry some rail caps are bad. 2200uF 120v 105° 30x30mm somewhere i read where you found a replacement for something like this?
I'm sorry but if I did, I don't remember. Is that size difficult to find?
I rarely purchased caps from anywhere other than Mouser or Digikey so if I did, they likely came from there.

Yes. Haven't you done this before?
You generally have to supply a high-side B+ to get the high-side drive.
