rvwheels Posted April 3, 2018 Report Share Posted April 3, 2018 ISL 400. Having trouble with starting process. Turn the key on, dash display comes up, hear all the buzzing etc. but in about 5-10 seconds all goes out and turning the key to start nothing happens. Thought maybe bad batteries so installed new, same condition. Called Freightliner and went through their suggestion of locating main power cable and in line fuse. Bypassed fuse with direct connect, same condition. HELP!!! Quote Link to comment Share on other sites More sharing options...
