Went to start the truck to move it before the windstorm we're supposed to get.
Checked the NOCO before getting in, and showed charge 100% and in the green.
Turned on the battery disconnect, hit the master switch. Battery gauge in the green.
Truck to ON, ABS clickity clickity, Start...
Click.... Click... Everything's dead.
Much trouble shooting that went nowhere...
Unhooked all the wires, put the charger on each individually. All 4 showed full 12V charge. Hit all 4 with a 100A tester.
The two that were in parallel from 0-12V both went dead instantly.
The two that were in parallel from 12-24V showed great condition.
Rewired the two good one in series, fired the truck up and moved it. Unwired them.
So the batteries are the original 6TMF's from when I got the truck 2nd hand a couple of years ago.
With a date of Sept 07 on them.
So I knida assume that at 9 years I should be happy and move on.
But why did two fail at the same time, and should I be worried about some oddity killing them?
Oh, and if that's that, any comments on NAPA's 8d's that are like $200/ea?
Thanks.
