Hey everyone, I've been googling this and getting answers from bad BNS to bad batteries to alternators. So I thought I would post my situation and start a fresh discussion.
Warning comes on after about 10-15 seconds after car is started. Front starter battery is a mercedes battery less than a year old. Consumer AGM is a DieHard and has been having some problems as of late with "consumers off-line" after sitting for a week or so, so I figured I'd replace that before going any further. No effect.
I hookup up my SDS. Lots of control modules complaining about low voltage and other minor complaints. Clear all fault codes, and started vehicle again and took for short drive. Still getting dash message but NO FAULT codes being thrown by the BNS module or anything else.
Voltages are suspiciously low. With engine running at idle, only 12.3 at cigarette lighter socket. SDS says 12.1v on the title bar, and when I go into the BNS module and look at actual values, it says
#180 Terminal 30 11.6
#181 Terminal 30a 12.7
I saw a brief red error message flash abouts the braking system that went away...I presume a low voltage glitch.
Thoughts?
Is the alternator bad? Any fuses I should double check?
