I am stumped and need of help. The mower deck on my 3 year old Raven will not work. When I pull up on the red deck PTO switch nothing happens. I have replaced a blown 100a 58v bussman fuse. Of the three Bussman fuses. I replaced the one in the middle. I checked the seat and PTO switch with meter. Checked the 48v pack and it shows 50.2v. Out put to pack was 74v checked on the grey plug going to pack. Checked the large red Deck connector. Have 12v to center of plug when PTO switched engaged. Never got voltage on main outer red and black on the deck connector. The mower moves fine when started, but will only run a few seconds on battery power. Will a new battery pack fix this? Any ideas? Really could use some sort of service manual.

Go to the 100a fuse rail. It is next to the rear right wheel. (Would be your right side, if you were standing behind the mower).
There is a 100a fuse that is likely blown. You can't see this fuse until you remove the fuse bar that has 2 100a fuses. IT is the one that is towards the front of the mower. There is a black controler that is in front of it and obstructing the view of the 100a fuse that sends power to the blades.
I know.. cause I am dealing with the same problem right now. Mine was blown, but even after i replaced that fuse, its still not engaging. I may be dealing with a bad fuse and a bad controller. They say thought, its usually just a fuse replacement and you are good to go.
Look up LarryS on this forum, he has parts and can help. Good luck!
