Hi folks,

Please give me some hints.

Replace 2 new batteries and are doing the same thing. Batteries don't have enough juice to start the engine after sat for 2 days.

I tested the battery terminals when the engine running with 14.4V

I disconnected the neg terminal and check for load drawing when key off. Nothing is showing on the VOM.

2 new batteries are Bosch and AutoZone Gold.

Alternator? but I have 14+ volts?

 

will not start? does it crank? is the starter spinning?

 

yeah^ is it turning over or just tick tick or nothing?

 

You need to check the voltage of the battery after two days with it connected to the truck. If the battery is still showing >12v, it's very likely a weird starter problem.

 

Engine turns over for a couple times and went to tick tick tick....

I can jump start it and will be fine for a day, but after letting it sit overnight, next morning won't start again.
