Toyota IQ2 Battery Warning Light

[mds33]

Battery warning light is faintly glowing. Car is charging, voltage stationery 12.5 up to 14.5 when moving. Belt is tight.

Battery has been changed to no effect. All electrical items are working OK.

When right turn indicator is activated the Battery light flashes but not when left turn activated.

Any suggestions please

Stationary voltage is to low, should be over 14.

Thanks for your response. I’ve rechecked the voltage

Ingnition on,engine off, 12.5 

Engine started - stationery 14.1-2

Engine 2000 revs 14.3

stationary, engine idle, with lights AC on 13.9

not professional volt meter

That sounds normal, did youbtry to clean the negative cables on the Battery and other grounding points under the hood?

 the Battery warning light has now gone off without any intervention 

Baffled 🤔
