Tech Tip: Cranky Honda Civic Starter is a Grind Eagle River AK
A Honda Civic owner may complain that the starter motor intermittently grinds while cranking the engine. The cause may be that the female terminal at the starter solenoid may have spread apart, causing a loss of current to the solenoid. To correct the condition, replace the female terminal at the starter solenoid.
Tech Feature: Solving Intermittent Electrical Problems Eagle River AK
Intermittent electrical faults are the bane of the auto repair business. If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn't hiding from you. It's a persistent fault that can be isolated by a systematic process of elimination. Not so with intermittents. Chasing intermittents is like chasing ghosts. One approach that's often used is to wait it out.
Alternators & Starters: How and Why These Hard-Working Components Fail Eagle River AK
Most alternators fail electronically long before they wear out mechanically. Even so, the shaft bushings and brushes are also wear items that don’t last forever. These parts can also be ruined if the alternator is mounted low on the engine and is subjected to road splash that contains salt water or debris.
Tech Tip: Mercedes-Benz A/T Fluid Leaks at the Electrical Connector Eagle River AK
If there is transmission oil in the wiring loom, wipe it dry and blow out the plug at the transmission and ECU connections. The contacts can be cleaned with commercially available contact cleaner.
GM Tech Tip: Inspect and Ensure the Integrity of Wiring Harness Connectors Eagle River AK
When servicing a vehicle for any type of customer concern — such as miscellaneous DTCs, intermittent driveability concerns, hard start, no start, incorrect gauges, inoperative air conditioning systems, service engine soon lamps illuminated, 4WD lamp illuminated, instrument panel gauges inoperative or cruise inoperative — the following steps are imperative.

Alternators Are the Heart of Import Electrical Systems Eagle River AK
The alternator's job has definitely become more complex during the past decade. Today, that threshold is rapidly advancing toward 100 amperes of current which, among other things, must power innovations like heated seats, heated glass, sound systems, electronic power steering, air injection pumps, steering, braking and valve- train controls.
Battery, Charging & Ignition System Diagnosis: Getting around Those Difficult-to-Diagnose Faults Eagle River AK
What do you really need to know about diagnosing and repairing starting, charging and ignition systems? Basically two things: that electrical and ignition problems are often difficult to diagnose (especially intermittent faults), and that a lot of electrical and ignition parts are unnecessarily replaced in an attempt to repair problems that are hard to diagnose.

Here, you can know some possible trouble areas as well as ways to prevent repeat failures for Subaru electrical systems. Component locations, test procedures, and remove and replace steps are pretty much the same across the entire model lineup. Read on to know more.
Evolving Ignition Control Systems Eagle River AK
The function of the distributor on throttle-body injected engines is to determine when each cylinder reaches top dead center (TDC) on the compression stroke. When the cylinder reaches TDC, the distributor triggers the ignition coil to provide a spark to the compressed air/fuel mixture.

Ignition Control Modules Eagle River AK
Although most of us seldom think about an ignition module until a tow truck arrives with a cranking, no-spark problem, the ignition module is still an important part of ignition system diagnostics and repair.
Servicing Mazda Electrical Systems: Starting and Charging Diagnostics Eagle River AK
The first step is to confirm the battery condition. Start by checking the battery with a hydrometer. If the hydrometer test shows a good state of charge, disable the ignition system and crank the starter for about 30 seconds, noting the voltage. It shouldn't drop below 8 volts and return to the 12.5 you should have started with.

Tech Tip: Subaru Ignition Coil and High-Tension Cables Eagle River AK
When diagnosing a misfire code(s) P0301, P0302 P0303 and/or P0304, there is the possibility that the ignition coil and/or high-tension cables could be the cause. In addition to the information published in the service manual, use the following procedure to check the ignition coil and high-tension cables.
