How to Replace an Alternator in an Auxiliary Generator on GMC Yukon XL 1500?

Begin the auxiliary generator replacement by disconnecting the negative Battery Cable then removing the Drive Belt. Begin by unplugging the auxiliary generator electrical connector then remove bolts from the generator before extracting the generator itself. First lower the boot to access the terminal stud on the generator cable. Then remove the generator cable nut and disconnect the cable. First remove the bracket bolt if needed before removing this bracket from the system. Put the bracket back if it was removed then bolt it to the bracket and tighten it to 50 n.m (37 lb ft).

Proceed then by reconnecting the electrical connector for the auxiliary generator while restoring the Drive Belt before completing with negative Battery Cable reconnection.
