Where Is The Mercedes SL63 Starter Relay Located?
Trying to find the Mercedes SL63 starter relay can catch you off guard the first time you look. Most often, you'll find it tucked inside the fuse and relay box in the engine bay, typically on the passenger side near the fender. You may notice a black or gray plastic cover that pops off to reveal the relays. Mercedes likes to stack several relays close together, so don't be surprised if you confuse them at first glance. The quickest way to sort out which one is the starter relay? Check the diagram stamped on the fuse box lid or match the part number with the one you’re replacing. Before you start pulling things out, cut the power by disconnecting the battery—no one wants a surprise spark in a tight engine bay.
What Are Common Symptoms Of A Bad Mercedes SL63 Starter Relay?
When the Mercedes SL63 starter relay begins to fail, your car's behavior changes in small and big ways. Sometimes you turn the key or press the button and get silence—nothing happens. Maybe you hear a faint single click, then nothing more. Some days the car starts without issue, but other mornings, there’s not even a cough from the engine bay. Strangely, the dashboard lights up, giving you hope, but the engine doesn’t turn over. A burnt smell, like melted plastic, is rare but very telling. If you notice any of these signs, the relay should be high on your list of suspects.
How Do You Test A Mercedes SL63 Starter Relay?
Testing the Mercedes SL63 starter relay doesn't take much time. Pull the relay out with the ignition off. Grab a basic multimeter and check the relay’s main contacts for continuity. Feed 12 volts into the control side—if the relay doesn’t click, or if power isn’t making it through when it clicks, the part is past its prime. No click, no continuity, no luck. These checks help avoid guessing games and zero in on the problem without swapping out parts blindly.
Can You Replace A Mercedes SL63 Starter Relay Yourself?
Replacing the Mercedes SL63 starter relay is straightforward enough for any owner willing to get their hands dirty. After disconnecting the battery, pull the old relay from the fuse box; no special tools required here. Plug in the new relay, double-checking to match the part number. Hook the battery back up, cross your fingers, and see if your car springs to life. Doing it yourself keeps costs low and lets you skip the hassle of scheduling dealer visits unless something else turns up.
What Can Cause A Mercedes SL63 Starter Relay To Go Bad?
A number of things can end the life of a Mercedes SL63 starter relay. High heat, electrical spikes, and the gradual wear that comes from repeated engine starts all play a role. Moisture can sneak in—especially if you live somewhere humid or wash your engine bay often—and corrode the contacts inside. Sometimes, old age alone is enough to make the relay unreliable. If your car’s hard to start, consider both the relay’s age and any signs of water damage before ruling out other causes.
