Low voltage on display screen

[mtnkevin]

After starting my 2007 155 the screen reads low voltage for a few seconds then disappears

What’s up??

Probably your battery on it’s way out. How old is it?

Could be your voltage regulator, or a problem at the 30A fuse. Those fuse pigtails have been known to melt. Maybe you're getting a bad contact there. Check your voltage at the battery and on either side of the main charging fuse. When running, it should be between 13-14v. If it's your V-regulator, DO NOT use a cheap knockoff. I had one literally catch fire once.
