Hello all. Hoping to get some help on an issue my raven developed yesterday. Started out working fine then out of the blue raven wont move In electric or gas mode also the mower deck stopped working as well. I disconnected the 48v battery pack and get 50 volts at the grey connector on my multi meter. Pull the panel off by right tire and 3 100 amp fuses look to be intact. Any suggestions on what to look at next or how to do any further tests on the fuses. Thank for any assiatance

Did you check you battery's on the 48 volt back side? you may have to separate them and check them under load. But first do you have a 48 volt charger if so try charging first if you get it running battery's are low or bad or charging system is not putting out enough voltage for powering wheels and blades.

Yes I did check the voltage at the battery. Sorry for the long delay in responding. It ended up being the fwd contactor. I took it apart and cleaned it and everything works again for the time being

Good to hear you got it running again.
My two cents for the future, you can check to see if the fuses and contactor are working correctly by just checking to see if you have voltage at the nut that holds the fuse onto the metal holder that attaches to the contactor. Make sure you have a good ground point for you meter. If you do, than most likely a drive controller issue. If not, chase it back all the way to the grey plug on the battery and see where it starts and stops. They are all connected together.
