hum and clack clack from the engine compartment

Hello guys, I bought a vacuum cleaner and an air compressor for the cigarette lighter on the I-Net. Vacuum cleaner worked well, no air came out of the air compressor, only the one from my tire…but that’s the little problem. The part broke my cigarette lighter fuse. Also no problem, new fuse in. But since then I notice funny noises when I turn the ignition key 1. It makes clack clack before the engine starts. I mean v If I only turn the ignition key half-turn so that the electrical system in the car goes on, a buzz from the engine room comes all the time, when you open the bonnet, it is inaudible. As soon as the car has jumped on, the engine noise overtones the buzz. Have tested all the lights, climate, windscreen wiper and window lifter etc., everything works so far. It also does not light up a warning light. But I mean this clack clack before starting the mot ors, and the summing from the engine compartment I had not had before the attempt of commissioning the air compressor over cigarette lighters.
