COB build flickering again..

When I turn the multimeter to the 2k ohm setting it reads 1. When I touch the + lead to the + on the led and the - lead to the - on the led it still reads 1 on all 5 cobs.

Could you explain further what you are asking me to do with the pot wires?

What happens when you touch the leads together on your meter?
 
If I had one of these suckers overheat and become damaged, could that be what is causing the flickering and the 35watt draw issue?

Ok so it seems your led's are not leaking. eliminate the chips one by one and see if the flicker stops. If it still flickers then try this, Use the VDC setting( or VAC if your input is not direct current) check the power input of the driver, if the voltage is steady when the chips flicker then the power supply is good, This pretty much points to the driver.
 
Is that a different setting on the multimeter?
Yes...I think it is on the left side of your meter, with the big V on it.
Try turning that to 200, and put the positive lead on the positive side of the LED, and the ground on the negative part.
Read the numbers on the display.
Record the numbers by first selecting a writing implement of your choice. I would recommend a pencil.
Utilize that writing implement to scribble a happy face on a piece of paper.
Write the number you read on the meter onto the paper below the happy face.
Rinse and repeat.
 
I've just rebuilt the entire thing.. a faulty cob or a faulty driver? Am I wrong to narrow it down to these two just yet?

Ok, will do! Thanks for the details. I really hope it's just one of the cobs at this point..

The voltage readings were all slightly different negative numbers -.3to-3
 
If you want to test the voltage drop across each COB turn you multimeter to the diode setting bottom right.

If you're getting negative numbers when testing your circuit without the driver connected that probably means you have it wired wrong or you're shorted to the heatsink. Take your probes and place them on your heatsink here and there. If you're getting readings after a moment you're shorted to the heatsink somewhere.
Pictures Al, pictures please.

when testing the cobs I only get readings of 1. When I place the leads on the heatsink I get a reading of zero.
