Alex prostar star with all your ground wire one of them it’s broken or weak I have a similar problem the truck it’s not getting enough ground

 

Was this problem resolved, we are having the exact same issue?

 

Hello there guys, I drive a 2009 international pro star with an ISX Cummins engine in it. Since last year the truck would run good and whenever I shut the ignition off and leave the key in the start up position to the right it stayed on without ever loosing power of any electricity. I noticed that after a long while it would she of the load from the air bag suspension and later on during the night, the whole electricity would shut off also causing me to restart the engine. Anyhow towards the end of last year I noticed that after leaving the key in the same position aster shutting of the engine, it would start to she off the load and not the whole electricity shuts off immediately leaving me with no working electrical power. What is the problem and if it's a fuse problem please help me, I noticed that people have posted similar issues and have gotten very helpful responses. Thank you

 

Sounds like load shedding is kicking in when it senses lower battery voltage. There are few posts here about load shedding and it does along with how to bypass it if you chose.

 

I have an 2011 Prostar with the triangle coming on on the dash. Most all gauges don’t work only rpm and oil pressure work. The kick panel on the lower left of clutch houses the body controller. My problem is intermediate. While my truck was working properly I removed the connection that is vertical nearest to the firewall and recreated the problem. It’s a bad connection to the body controller that caused the problem. Internatinal is known for bad connections kids like the problems they have with head light harness. Hope this helps.
