    Hello!

    I have a 2011 T370 and it's doing the same thing. Blowing the 10 amp fuse. Did you find out what caused it?

    my problem went to a bad wire going to my lift axle which had an electric switch. It was broken inside and shorting out and the installers had that running off the ignition switch, so It ended up blowing that fuse. Replaced the wire and the issue went away
