Hi Jim. Sure send me your email. I can send you the manual for sure. Where is the downloadable one located on the Ryobi website?

Hey Jim, The fellow from the help desk emailed me a Ryobi Riding Mower Repair pdf which is a 55 page electrical component troubleshooting guide for the mower. Is that what you were referring to? Funnily enough the problem I found was not in their document. Yes the batteries were fully charged before the receptacle failure. I heated up the black layer and was able to remove it from the receptacle so will see if I can fix the board once I get it removed. It is held in place with tamper-resistant screws of all things, so I had to buy a special tool.

Thanks Jamis, that's good to know, and I appreciate your suggestion re the fuse. Turns out it is the Charger Receptacle which has failed. The power wire to the blue connector is open (the live side of the blue connector reads 52.4volts). I guess there must be some electronics hidden beneath the layer where the wires attach to the back of the receptacle. Not much chance of getting under there to fix anything. I ended up contacting Ryobi and they have ordered a receptacle for me, but it is on back-order so who knows how long I will be waiting.

I have encountered an issue with my rm480e mower. I was checking the voltage at the charging port yesterday and while I had my meter connected to the charging port with alligator clips I turned on the key to see if there was a voltage drop, and then turned it off immediately. Well I guess the lockout to prevent the mower from turning on while charging must have kicked in because even though I have removed my meter the mower is totally dead. Turning on the key does nothing and there is zero voltage at the charging port. What do I need to do to reset my mower? Anyone got any ideas? Thanks, John (I have not been in touch with Ryobi yet and am not too sure the warranty would cover user stupidity (if I am to blame))
