Battery Charging

When charging the battery on a 2018 Ducato, do you have to connect the charger direct to the battery terminals, or can the connections under the bonnet be used. Hope this isn't stupid question.

It's always best to connect directly if you can.

If you are charging the Engine Battery, and the battery isn't visible, on some vehicles there is a large Red jump start position, in the engine bay, (Like my sprinter the engine battery is under the floor between the front seats ) you can connect to this with the red lead and the black to a good earth, engine block or Chassis .

For the leisure batteries than its best to connect directly, either individually or Red ( Positive + ) to one battery and black ( Negative - ) to the other Battery.

There is no such thing as a stupid question, If you don't know what the answer is, It's stupid not to Ask.

A suggestion to do with this fault, is never start your engine while connected to an external charging source, this can corrupt the airbag eeprom on the ECU.
In other words, don't start you van while connecting to EHU.

Gentlemen/Ladies, I tried using the contacts under the bonnet to charge the battery, it appears to work. I used a multimeter on the contacts to check the voltage, connected up my battery charger and when it showed the battery fully charged, I checked with multimeter again and the voltage had increased. It seems to be more convenient than pulling up the cab floor.
