Thread: new battery, no juice

While you guys disagree about the resistance, my bet is, the battery wasn't fully charged to 100% before use, it's very important to fully charge a battery before putting it in the car especially if you are going to be starting the engine over and over again making adjustments.

I agree - my old '90 got a new battery, new solenoid and considered new cables before we changed the starter in the AutoZone lot one morning. Started fine at home, would not turn when I went back out. Starter "tested" good on their machine, but would not spin the engine.

Most of those machines only do a free running test on starters, not a loaded test, so many weak starters will check out good.
Once I rebuilt the engine in my Ford pickup. The starter worked fine on the tired engine but couldn't spin the fresh rebuild.
