Electrical System Diagnostics

Diagnosing electrical issues including battery, alternator, starter, and wiring problems.

1. Battery testing: Check voltage, load test, inspect terminals for corrosion.
2. Alternator output: Test charging voltage and current output.
3. Starter circuit: Verify power to starter, check solenoid operation.
4. Wiring inspection: Look for damaged wires, loose connections, frayed insulation.

WARNING! Disconnect battery before working on electrical systems to prevent short circuits and injury.

Transmission Issues

Identifying and resolving automatic and manual transmission problems.

1. Check transmission fluid: Level, color, and condition.
2. Test shift points: Note harsh or delayed shifting.
3. Inspect for leaks: Around seals, pan, and cooler lines.
4. Scan for codes: Transmission control module diagnostics.

CAUTION! Transmission repairs require specialized tools and knowledge; consult professional if unsure.

Braking System Troubleshooting

• Spongy brake pedal: Air in brake lines, master cylinder issues.
• Brake noise: Worn pads, rotor damage, caliper problems.
• Pulling to one side: Stuck caliper, uneven pad wear.
