Hi all,
recently noticed something on my car that I need a bit of help with.
Had a slow start on the car the other day, hadn't driven it in a while and the voltage cut off on the dash camera was set wrong.
Took it for a drive and noticed the charge voltage didn't get above 13.1 volts (ARB Linx) Stopped into Supercheap and got the battery tested and came back 'good with a charge voltage of 13.7v.and a CCA of 554. I then drove it home and noted a normal 13.7-13.8 charge voltage.
Topped off the battery water and left it on the CTEK overnight with no errors from the charger.
I have now noticed that when driving around I see a variable charge voltage from 13.0-13.7 which fluctuates. Does not change with RPM. Will be 13.7 at idle and 13.0 when driving but also flips back and forth on those numbers.
when I got home (5min drive) to check the accuracy of the linx with a voltmeter the linx showed a consistent 13.8v which was confirmed by the multimeter.
The other thing I have noticed is my second battery (connected via a dcdc charger) will show 12.7 when I start the car but drop as low as 12.1 for the first few mins of driving until the main battery's has enough charge voltage to start the flow of charge.
Any thoughts appreciated.
hopefully it all makes sense!
Cheers
