    No warning lights at all. All that is in the scanner are pending or past codes but the panel is clear .

    Not sure what a cluster ground is, but, I have noticed that on occasion the battery is not fully charged and when I check the alternator output it is very erratic. Some times just making battery voltage and then jumps up to 13. 8 and even 14.01 briefly. The next time I check the system it is running even at 14 volts ??? New AGM Odyssey battery 6 months ago. Can a bad alternator behave this way with the warning light and tach/speedo jumping around and then all settles down?
