Good evening I'm new to this forum I'm hoping you guys can help me.

I have a 2007 T190 I am not a mechanic but replacing the alternator seemed not to hard to do.I had a charging issue that has been resolved
but now, I have no forward or rear travel with hydraulics it is like it has the brakes locked but I have up and down and tilt boom any suggestions.

if you did not disconnect the battery first before changing out the alt. ,maybe you touched a hot lead to ground and blew a fuse. big W.A.G.
