Hey guys, first thanks for the help and advice! I honestly thought is was electrical also. Turns out all 3 "new" crank position sensors were bad. I took the original old cam position sensor and put it where the crank sensor resides at the correct angle so it could pick up the reluctor wheel signals and BAM, fired right up. Id love to bash the manufacture but i wont. I remember this happening a few times before, new defective part. 20 years ago changing a 3rd gen camaro TPI fuel pump 2x before realizing I should bench check it before i drop the axle, tank and muffler....lol good times

Nice! I hate new defective parts. They can really cause headaches.

ok guys, back at another nightmare. 2006 6.6 duramax 4500 series. 42k miles Auto. Alternator wont charge... New alternator, then new AC Delco alternator. 3 new Interstate batteries. New Bosch glow plug heater. Checked all fusible links. Have cleaned all junction blocks 2x. Swapped ECM and PCM from same identical trucks we have. Still no power being made from the ALT. Any help GREATLY appreciated... The truck has been parked since December. No lawns to cut in the winter, lol

Any voltage on the exciter wire while running? Ohm it out? Bench test alternators?

I had a issue years ago with my 12v cummins. Ended up running a additional ground cable from one alt mounting bolt directly to the one battery. Solved my problem. And has been fine ever since. May not be your problem but figured id chime in.

so I'm not getting any power at the isolator module, the exciter wire. The truck is at 10 volts under full load upon startup. Jumping the exciter wire to 12v turns the alt on. Can I bypass the exciter wire on the module and connect the grey and red at the plug behind alt? Go old school...

Can you scan that in or make it larger? How did you narrow it down to drl circuit? What do you believe is the issue? I can't get medium duty wiring else I'd look into it further for you.
