Electrical problems with 07 Yukon

[schweg]

i learned how significant the BCM truly is by watching this thread. Your description of "clicking" from the starter solenoid but not turning over had me convinced it was a simple power/connection to starter issue, maybe even an ignition switch? I couldent have been more wrong, I have a tech2 and threads like this "school me" that vehicles have changed so much, Allways diagnose with test equipment and leave the guessing to those fortunate enough to be troubleshooting a 1967 volkswagon beetle!

Yes, if I had just started with the tech 2, I would have saved a lot of money and time. At least now I have a shinny new battery cables!
