I keep getting a Voltage Message on my Skyview System. I have a ODYSSEY EXTREME DRY CELL BATTERY installed. The voltage meter in the system shows the battery going over 16v very often. Is this level an issue?
 
That's not a battery problem - it's an alternator regulator problem - and it's serious.
 
Could be a wiring problem (if you did wire it, yourself): my MGL's voltage sensor can be put on many places, providing different voltages every time ;-(
