1. Conditions Leading to Battery Problems

If a customer complains of poor battery performance (i.e. slow start, no start), perform the following quick checks prior to detailed diagnosis or parts replacement.

A preliminary check of these items will, in most cases, reveal the problem without time consuming detailed diagnostics.

NOTE:
As a result of product testing on returned parts, 60% of the returned alternators and 20% of returned batteries are classified NTF (No Trouble Found).
