Onan 7.5 gen set 05 Meridian 36P

[Why not]

I pulled the unit out of storage to get it all ready for a summer trip.
I found an issue I cannot resolve even after reading the TS guide from Onan.
I cannot get the gen set to do anything. I have tried all three switches inside. I also replaced all 5 batteries...
I checked the oil level, water level ect. Still not even a turn over. I used the momentary switch on dash just to see and nothing. Does anyone know what could have gone wrong with it sitting since December ???

Thank you,

there are 3 fuses inside the gen set they are under the right side of the front cover you will get the radiator cap hose and the fuses there also the battery connections are on the back bottom of the gen set they may be corroded from the winter. Hope this helps mike

Also, try the start/stop witch on the generator itself and make sure the circuit breaker on the generator is set on. Use a voltmeter to make sure you have power to the generator connections on the back bottom where the battery cables connect to the generator.

Thank you,

Thank you so much. I unbolted the radiator fill cover and the fuse was blown. 15amp mini. Fired right up, runs like a champ again.
Again, I am a newbie and really thank you for all your valued support.
