Getting the best from the Tudor TB457
Holiday over, the car has sat at the airport for two weeks and the dashboard barely lights up. Tighten the hold-down clamp so the battery cannot rock on bumpy roads. Jump-starting the car every few days is a clear message that the battery needs replacing.

Six cells of about two volts each make up a typical 12-volt battery. Tractors and trucks use robust flooded batteries. Top up only with distilled water, after charging, never above the mark.
