This is what I like about this site... education in all forms! Engine and English. Please excuse my spelling ... viola it is. (No, not being sarcastic). I am guessing, even though it is a Mercedes, it needs all 24 volts to start and gets picky when it drops too low.
Our first indication there was a battery problem was it did not sound exactly right on start up. We thought that was because we were in the polar arctic north of Ohio in fall and the temps were down into the 30s. Then we noticed the voltage started dropping slightly just before start up. We sit there and wait while the gauges flip/flop, might as well read the info the truck is giving us. Yes, it does sound different when starting in the cold, particularly if we forgot to plug it in the night before. But the voltage dropping - we knew it was getting to be time. Oh.. the other thing was the power port on the dash stopped working. No wire issues, no fuse issues, no reason. Installed new batteries, it is fine now.
Checking the cables is a really good idea... looking good on the outside does not necessarily mean much.
Thanks again.
