I'm actually debating it. I pulled it while sitting here and it doesn't trip the light, but maybe I need to be rolling for it to do such. But that is one of the things I'm going to try tomorrow. Right now I'm just hoping my mechanic and I can dig in and maybe find it. I hate by passing problems like that, but glcant sit forever. Customer will want their steel lol

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
