Looking for Help!! Voltage issues 2016 International.

Did you solve your voltage issue

 

Had one in the shop today doing the same thing. Voltage would climb with the key on acc. I traced the issue to an incorrectly wired starter that melted the wiring pretty bad. It spread to the fuse box on the fender mount and cooked the terminals going to the starter and ecm relays. It cooked the ecm as well it was verified with a test ecm and checking the harness for resistance. That's what the issue was with the 13 letter s spreader I worked on.

 

I'm a little late but hope it may help someone else.

 

The OP made 1 post 2 years ago, never to be heard from again.
People are still responding to it?


And lest we forget... this is a ProStar we are talking about.
They are well known for electrical issues.

 

Have a 2016 international 4300 , been having voltage issues i replaced the alternator twice and all 3 batteries still not holding charge i need help asap.

 

Are you saying that tht alternator is not charging or that tht batteries are not maintaining a proper charge?
