To check if your TomTom is being charged,connect the charger ,power on the unit , tap the bottom right of the Driving view to get to the route summary screen. If the battery is being charged, the word Charging is shown under the battery symbol on the right. If you don't see the word Charging, the battery is either fully charged (indicated by a completely filled battery symbol) or it isn't receiving external power.
Your battery is weak, or your your alternator is not charging battery.
The battery charging system is not working properly. The truck runs until the charged in the battery drans to the point the engine can no longer run.
Be careful if you're charging the lithium battery with a generator connected through an isolator.
Check charging system with a voltmeter: Fully charged 12.8 without engine running 13.8-14.2 with engine running
Stop driving until the charging system and battery have been checked for an overcharging condition.
No reset buttons. Is Likely a bad battery or charging system failure. The EFI system requires a specific amount of voltage for it to function, If not the engine will shut off and will not restart until the battery is charged/jumped and/or charging system is restored.
Charging system problem. Normally this means there is a problem with the alternator.
Driving with the battery light on can be risky as it indicates a potential issue with the charging system. Your car's battery may not be charging properly, causing it to lose power and potentially stall. It's best to avoid driving and have your vehicle checked by a mechanic as soon as possible.
If the engine is running, then no. The alternator constantly keeps the battery charged.
It has to be a dead charging system.... usually a short internal in the alternator
The alternator may not be charging it enough. With the engine running at an idle check the voltage at the battery with a DC digital voltmeter. It should read from 13.5 to 15.5 Volts. Anymore, or any less, and the alternator is suspect. You might also have a defective battery.
