The light bulb is actually a very tiny wire that glows brightly when hot, and is a worse conductor than the wires around it, so it gets very hot inside the bulb. The consent submitted will only be used for data processing originating from this website. Any arcing is caused by amperage flow, slight arcing is normal. The battery being charged and the battery in another car being used to supply the charge are both examples of this. normally the negative terminal will spark when you connect the cable if something is drawing current In some cases it could mean a short but normally you can expect some minor sparking because of the many things that draw a dedicated current from the battery. Some or little sparking is completely normal for a car battery when connecting the charger or jumper cables.
