Why do I hear a ticking noise in my Fuse Box?
When you hear a distinct, repetitive ticking through the screwdriver, you’ve found your troublesome relay. Relays control a high-current circuit using low current. It makes it possible to control things like the headlights and the fuel pump without running high-amperage current into the passenger compartment.
Why do I hear a ticking sound in my engine?
Rod knock could be the possible reason for a major engine issue. When the bearing connected to the rod wears off or gets damaged, the rod knocks around the crankshaft and creates a metal-to-metal sound. You will hear a rhythmic, loud ticking noise in engine when acceleratin g.

Why does my car relay make a clicking noise?
Clicking noise in your car’s fuse box is caused by a relay that is turning on and off rapidly. This can be caused by a computer failure, resistance in the ground wire for the control side of the relay or high resistance in the power supply to the control side of the relay.

Why does my flat 6 make a ticking noise?
The flat-6 is a very “ticky” engine – tappets and injectors (on the DFI engine) at start-up and also when warm. Radiated sound from the engine gets reflected from the ground and out the sides of the car.

What to do if your fuse box is clicking?
If that relay also clicks constantly, you need to run more tests. If that relay works fine, then the original relay that was in that spot is faulty. Simply replace that relay with a new one. Identify the terminals on the relay. Look at the terminal labels on the relay.
