Q: Loud buzzing before the engine cranks
The car couldn't start. Before this happened, the cranking was weak. The battery works well and has lots of power. The car can be jump-started with no issues. I had the terminals cleaned as well as the cable ends that had some corrosion on them. I also tightened ends to terminals. Now, when I put the key in the ignition, before the engine starts cranking, I can't hear the clicking sounds anymore. Now, it's buzzing very loudly. What should I do?
