If the vehicle is slow starting in the morning, when everything is cold, but performs well at other times during the day, that is an indication that the battery may be getting weak.

Some battery maintenance is always advisable, checking the water level if possible and adding distilled water.

But if the vehicle is hard starting even when it is warm, and the battery should be well charged, that is an indication that the starter is beginning to fail.

Unfortunately, they can occasionally fail in a rather catastrophic manner, as I learned recently, taking some of the electrical systems and electronics with it.

That's the analysis I've been applying.

Yikes! Short-circuit flyback effect?
