Is the Alternator the Issue?

In this month’s post, Louis from New York provides a diagnostic routine to quickly determine if an alternator is bad and “know for sure without messing around.” He uses the case of a 2014 Grand Caravan with 54,00 miles and a suspected failed alternator (wasn’t charging at all, and no…

The Evolution of the Automotive Battery

One of the components of the modern vehicle that has seen dramatic change in the last two decades is the automotive battery. At Clore, we often say that the vehicle battery has changed more in the last 12 years than the prior 60 years. With that in mind, we thought…

In this detailed post that includes some…

Got Good Ground?

I utilize a quick, reliable methodology for diagnosing vehicle charging system, starting system and drivability issues. It typically takes just 2 minutes and is based on proving that the ground system is functioning properly on every car or truck before moving on to more extensive diagnosis. I perform this test…

A No-Start Issue of Strange Origin

Today’s iATN spotlight is focused, like many we have spotlighted in the past, on an intermittent no-start issue, this time on a 2012 Ford. Unlike previous examples, this one did not originate with faulty wiring or a defective component. Diagnosis was further complicated by the fact that the problem did…
