Re: Onan generator does not start


First, this is a very old Onan.

I looked at the MDK series installation manual for this Onan and discovered the DC wiring diagram shows a 30A fuse. 
I was a little surprised by this because I have not seen an inline fuse in Onan installations done in the last 20-25 years.

We are having trouble transferring the pics from my phone ,but as I described the fuse is right off the back of the solenoid , I never knew it was there ,and I am pretty sure it was not installed by Amel .

Roland & Bill, Had a look at the fuse. It was probably an add on, but someone also said they had a fuse. Picture is attached. the wire with the fuse is connected to the same terminal on the back of the solenoid that the power supply is. The wire appears to lead to the panel on the side of the engine that has the switches, which makes sense. I don't know if yours or any other SM has this fuse, but mine does and it blew and preventing the engine from starting. The mechanic went right to it as if he new it was there, fixed it in five minutes.
Hope this helps,
