EC480 battery voltage Empty EC480 battery voltage

The vehicle battery voltage is showing around 4.5 volts on the EC480 however the engine seems to be starting OK. 
The voltage shows very low even after a good run to charge it up. 
Could this be a fault with the EC480?
The leisure battery volts read OK. 
Any advice would be welcome.

You need to put a meter on the battery to begin with. They are under a tenner and an essential in the van toolkit for me.

Good advice. I usually keep a multimeter in the van but we came away in a rush and forgot to put it in. I will buy a cheap one on our travels. 👍

I’ve got a couple of these, nice and simple and there is a Screwfix everywhere!

We passed. Screwfix this morning so bought the multimeter at under £10!
The battery is reading around 12v at the cigar lighter socket but will check the battery terminals tonight. 
I am beginning to think the problem is the battery reading sensor. Luckily our van is still under warranty so Marquis can have a look on our return.  
Thanks for the advice.

I agree. The van has to go back to Marquis sometime soon so will get them to have a look as under warranty.
