Service Solutions: Electrical Problems – Invisible Targets

To correctly diagnose invisible electrical challenges, sometimes, it literally takes all we know plus patience, suggestions from others and maybe a little luck. This story began innocently enough with an overheating complaint on the first vehicle. The second had intermittent flickering headlights and instrument cluster gauge fluctuations, so it was an obvious challenge. We will attempt to convey what was learned in locating the target causes of these electrical challenges.

Diagnostic Dilemmas: Harnessing in a Wiring Fault

During the summer, the speedometer on the Taurus would quit on an intermittent basis. Of course, when the speedometer would quit, the automatic transmission would default into an intermediate gear and fail to shift into the higher ranges. Although a local transmission shop installed a new VSS and performed other repairs as well, the Taurus ran only a few days before the problem resurfaced.

Directions: Will You Be Servicing a 100-MPG Vehicle in the Near Future?

Tech Tip: BMW Check Engine Light On and Vehicle Running Rough Due to Airflow Meter

If a customer complains of a check engine light on and a vehicle running rough, it may be due to problems with the airflow meter and wiring.

Tech Tip: Nissan Optical Distributor Test

Many Nissan vehicles have a power transistor controlling the coil (or igniter). The power transistor is a separate unit on optical distributors. It allows the signal sent from the ECU (low current) to activate the primary circuit in the ignition coil (higher current). This induces high voltage in the secondary windings of the coil, providing spark to the distributor cap and plugs. If this transistor is faulty, the necessary spark will not result.

Diagnostic Solutions: Alternator Testing Tips

When we’re attempting to diagnose a charging system failure, it helps to think of the battery’s state of charge (SOC) as a type of checking account. If we overdraw our account, we wake up the next morning with an engine that won’t crank. Or, if we overdraw our account and not balancing our account at the end of the day, we again are greeted with a slow-cranking engine and an overdrawn charging system account.
