Re: Help on CCM pull...

Man this is so convoluted reading the FSM.

OK, I don't have a 90 fsm. I have a 92, similar but possibly not identical. I will give you an idea of what I found and it involves scanning through multiple pages.

I was incorrect in what I told you above. But it is still specific and you are not using "any" ground. It says check the AC head ground which (in 92) is circuit 150 and ground point G106 (connector found on 8a-202-6, elec diagram on 8a-66-0, and ground dist on 8a-14-3). So in my opinion now, you'd be checking the ground point origin.

I think in your case, it might not matter but I can't say for certain. Obviously it would seem if you got a light between 1/2 and 1/10 you have ground at the connector!

Back to the original issue because I think it was lost here. Are you troubleshooting the CCM or or HVAC system at this point? What are the symptoms or issues? Also, did you do the battery reset that is recommended on 8a-62-0?
