I have noticed my 2006 F250 Diesel PU turning over a little slow for a few months
I clean the terminal ends and topped off the water with distilled water every 6 mo.
Then give the terminal ends a fresh coat of Black Krylon paint
This morning I cycled the glow plugs and then it just went click-click at 32deg.
I know everyone here knows the dreaded click-click sound
I got my gf's keys and jumped it off.
I had work to do at home and didn't have an appointment earily so that was good.
Just locked it up running for a hour
My Fluke VOM said it was putting out 14.8 volts dc at Idle
I put 2 batteries on it on 07/30/09, Walmarts best Maxx 27s,3yr. no pay for replacement
I wanted Interstates but money was tight so I got Walmarts, No choice then
Drove to Walmart and told them one of my batteries was dead, they said they'd check it
30 min. later I went back out and the mechanic told he had checked them and they both
showed good.
I asked him if he checked them hooked together like it was or seperate, he said together
I told him you couldn't check them together and had to disconnect one of them
This pissed him off so I told him I would get my tools and and do it for him
he said he would do it and apologized, I told him no problem
He checked the one he disconnected in front of me and it showed good
he asked if he could check the other one still hooked up to the truck and I told him yes
as it was not connected to the other battery now
He checked it and said it needed to be charged and it would take 30min. to do so
Then he would check it again
When I came back after 45min. they told me My truck was ready to go with a new battery on it
At no charge of course and they put the little felt pads under the new and old battery posts
Sometimes its hard to be humble
