What are the reasons for a car battery having power but no response when starting?
1 Answers
The reasons for having power but no response when starting include the following: 1. Starter damage: (1) Symptom 1: No response when turning to START. The starter electromagnetic switch is damaged. (2) Symptom 2: A "click" sound is heard when turning to START, but the starter does not rotate. The main contacts of the starter electromagnetic switch are damaged, or the starter winding is damaged. (3) Symptom 3: A "click" sound is heard when turning to START, and the starter rotates at high speed. The starter one-way clutch is damaged. 2. Engine ignition system failure: The symptom is that when turning to START, the engine can be rotated (100r/min), but the engine does not start. Unplug the high-voltage wire (or ignition coil), and there is no spark when turning to START. 3. Engine fuel supply system failure: When in the IG position, the "buzzing" sound of the fuel pump working in the fuel tank area cannot be heard.
