I have an 07 century with a cat. The problem we are having seems toonly happen when the ac is on and the compressor kicks in. However, it is still random meaning it doesn't happen everytime. We get a power loss, akin to turning the key off then right back on. This happens regardless of high or low idle. I am assuming its a bad ground or hot associated with the compressor but can not find it. Knowing freightliner it could also be just about anything.HTML:
Any advice would be helpful.
On a side note it does not happen while driving and no codes or faults are thrown.
