Case Study: No Start Diagnostics on a Cadillac by John Rogers
2001 Cadillac Seville SLS with 103,361 miles on it. Pretty clean car. Unfortunately, it does not start, nor crank, nor does the host of electronic gadgetry on this car work. The owner says sometimes he can disconnect the battery and reconnect and vehicle it will start and perform well. The owner had a battery charger next to it. Usually, a clear indication to me that the battery in the car is a paperweight.
I see a ton of bad batteries. People will have expensive stereo systems, fancy alarms, and they have a bad battery. They don't mind jumping the car 5 times a week. That spells disaster to electronics. Between, voltage spikes and the eventual backwards jump start it gets ugly fast. John pulls out his Tech 2, a MODIS, and does some programming to solve the problem.
