Firstly, No, I have not had the batteries or alt tested yet. That will be this weekend unless I am forced to otherwise but...
This AM was 30 degrees outside. The only thing I changed in my routine was I enabled the OSD via the dash button combination to monitor the voltage during start and while running.
While I sat with the key on I had my Lights, Nav/DVD player, and butt warmer on. The OSD registered 11.4 volts.
As I was turning over the motot, 9.6 volts was seen.
The truck fired right up and it skipped initially but cleaned it's self up really quick. 11.4 volts was seen.
It had that normal tightness that a cold engine does but it was not any where near as choppy as yesterday.
I get 100 yards down the road and the voltage has risen to 13 volts. I did notice a big spike too, glow plugs dropped off maybe?
2 miles down the road and I am at that red light again. Voltage has risen to 13.6-7 volts.
As I cruise down the road at 70 for the next 15 miles, the voltage consistently stayed at the 13.9-14.1 mark. With a high of 14.1.
I started running the heater at about mile 5 too and did not see a change.
The only thing I did was topped off my Duralast gold batteries with distilled water. Water level was not low per say but low enough that I felt they needed to be topped off.
The battery light did not come on at all??
The only other thing I can think of about this issue is on Monday, it was the first time I started the truck as it sat all weekend in 35 degree weather.
Any input guys/gals?
