That Dreaded Click: Using the Tap Test When Your Car Won’t Start | MyMechanic
So, What’s a Starter Solenoid Anyway?
Think of the solenoid as the starter motor’s tough older brother. When you turn the key, the solenoid gets the signal first. It then does two crucial things: it shoves a small gear forward to connect with the engine, and it acts as a massive switch, slamming the door shut to let a huge jolt of battery power flow to the starter motor.
The Roadside Tap Test: A How-To Guide
Here’s what you’ll need:
Something solid with a bit of weight, like a small hammer or the handle of a wrench.
A flashlight will be your best friend if it’s dark.
Let’s Get Tapping:
1. Make it Safe: First things first. Put the car in Park (or Neutral for manuals) and yank that parking brake on hard.
2. Find Your Target: This can be the trickiest step. The starter is a cylinder-shaped part usually found low down on the engine, right where it connects to the gearbox. The solenoid is the smaller cylinder piggybacking on top of it.
3. Clear a Path: Make sure you can reach it without getting friendly with a hot exhaust pipe or a moving belt. No rings or loose jewelry!
4. Give it a Tap: Firmly tap the main body of the solenoid a few times. You’re not trying to win a strength contest, just give it a good vibration.
5. Try the Key Again: Hop back in the driver’s seat and turn the key. With any luck, the engine will crank and start right up. Success!
It Started! Now What?
If the tap test worked, congratulations! But don’t celebrate just yet. This was a temporary fix, and it’s a massive warning sign that your starter is about to fail for good.
Keep it Running: Whatever you do, don’t turn the engine off if you can help it. Your next stop should be a workshop.
Get a Professional Opinion: If you're far from help, give MyMechanic a call. A failing starter will absolutely leave you stranded again, probably at the worst possible moment. We can advise you on the next steps.
When to Just Call for Help
If you can't easily find or reach the starter. Don't just start tapping random engine parts!
If your car’s engine bay is packed tight. Many modern cars make it nearly impossible to get to the starter without removing other components.
If you hear a grinding noise instead of a click. That’s a different, more serious problem.
If you’re just not comfortable doing it. Your safety is always the top priority.
