The Complicated Truth Of Alternator Testing Diagnostics
One test is not enough if you are diagnosing a charging system problem. All too often, the alternator is condemned as the source of the problem if only battery voltage is present with the engine running.
Seeing The Big Picture With AFR Sensors
Air/fuel ratio (AFR) sensors have become commonplace in today’s automobiles, taking over where traditional O2 sensors have left off.
Diagnosing, Servicing & Replacing Batteries
Just last summer, I had three batteries pass a conductance test, but fail to crank the engine on a sustained basis. The conductance tester indicated that these batteries were “good,” but they tested well below 100% capacity. In two cases, I was pursuing parasitic battery drain problems with used batteries. In another case, I had a new battery that would pass a conductance test, but not accept a recharge, said Gary Goms, Import Specialist Contributor.
Finding That Spark Of Genius: Diagnosing Cranking, No-Start Failures
By the dawn of the Industrial Age, the gasoline internal combustion engine had replaced steam power as the driving force behind America’s great economic expansion. In that day, a cranking, no-start condition could easily be diagnosed by testing the available spark at the spark plug. If there was no spark, we touched a test light to the coil negative terminal to determine if the distributor contact points were switching the coil on/off. If the test light blinked, the primary circuit was switching as designed, so we replaced the coil. A pretty simple diagnosis, right?
Shifty Battery Drain
Let’s go into the shop for a first-hand look a 2012 Ford F150 with a battery drain and no remote start.
AIRMATIC Suspension Solutions: Diagnostic Tips To Aid Your Repair Efforts
The Mercedes-Benz AIRMATIC suspension system was introduced in 1999 on the S-Class and has subsequently been used on the E-Class and most of the automaker’s SUVs. Keep reading for some key tips for common ailments to help you effectively get the system on these popular models in top-running condition.
Alternator Testing Diagnostics Are Getting More Complicated
One test is not enough if you are diagnosing a charging system problem. All too often, if only battery voltage is present with the engine running the alternator is condemned as the source of the problem. If this is the case, it means that the alternator is not charging, but does not reveal why.
AGM Batteries And Testing
Two of the greatest changes in starting/charging systems during the past few model years have been the expanded use of the Absorbed Glass Mat (AGM) battery as standard equipment and the accelerating pricing structures of both AGM and conventional flooded-cell batteries. In the past, I knew many shop managers who simply replaced any battery that
Catching The Electron Flow: Multimeters And Fuse Box Diagnostics
Gary Goms explains why the multimeter is the first tool he reaches for in his diagnostic tool box when diagnosing electrical system problems.
