OK I've figured it out. The house is a Winnie 2007 Journey with the C-7 engine. Tools you will need; a medium 6 philip head screw driver to remove the six screws holding the bed board over the engine - screws in the back piece, don't forget to pop the suspension pistons on the front piece before removing screws. (small slot screw driver does the trick. Remove the 8ea 1/2 inch bolts holding down the front and rear metal engine covers. The engine should now be exposed. Alternator sits on driver aft side just under the metal center of overhead engine cover (not removable). Using a long handled 1/2 inch drive, insert drive into belt tension pully frame and push toward passenger side to releive tension from alternator pully. Hook the belt using a bungy cord to prevet from belt falling off other pullys. I could not take the long handle drive out since it is long and rested with tension on engine house. Remove + terminal 1/2 inch socket and - ground also 7/16 inch socket. Remove the upper alternator mount bolt 3/4 inch socket. The lower bolt you will need either two 3/4 sockets or one close 3/4 wrench and one 3/4 socket. Remove this nut and bolt from the aft end of house. You now need to remove the alternator mount frame. You need a 5/8 inch socket to remove the upper blot on aft end of bracket and a 6 mm allen head socket to remove the lower bolt. This one you may need to soak in WD 40 to help loosen. You can also lift end of mounting frame to help break corrosion to bolt. It's pretty tight so be careful when removing. Once bracket is out use a J crow bar to lift alternator and free it from bottom mount. Re-install new one when it arrives.

Best of luck

Thanks, Dog, for taking the time to post the detailed description. I hope I never need it, but know where it is if I do!

Is the C-7 alternator removal similar to 3126?
