I have 2008 Volvo VNL 465, D13 with a manual trans 13sp. I gave a jump start to another truck and since then I get the code MID 140 PID 158 FMI 3. I know it related to High Voltage, but could it be my alternator to be bad? It`s output is sometimes 15.5V and if I turn my lights on it drops to 14.6V.....
Volvo VNL High Voltage!

Same happened to me. I was driving down Louisiana and all of a sudden in the darkness my headlight lit up like freaking hids and the cluster started going bonkers. Read 15-21 volts. Crap!! Stopped at the service plaza and turned truck off. Smelled burning as I opened hood. Alternator was done, son. I didn't have tools to remove it, so I cut the belt. (N14 with 3 different belts) and drove to a shop on batteries only. Made it and got a new one the next day.
I now replace alternator and belts every 2 years. Cheap insurance.KB3MMX and HopeOverMope Thank this. -

You just need to study how to remove it, finesse the old one out and the new one in.HopeOverMope Thanks this. -
I believe I had to thread it through each fan blade and over the fan hub.KB3MMX and HopeOverMope Thank this. -
