Might be worth a hard battery reset and see if the fault comes back again as it was stood such a long time before you started it again.

Thanks very much for the reply. I’ve been very impressed with the helpfulness and quick responses on this forum.

But you need to know you’re dealing with a complete Truck Newbie here. All I can find when I search for ‘hard battery reset’ is stuff about iPhones and Kindles.

What’s a hard battery reset on a truck and how do I do one?

I should mention that the batteries were disconnected from the truck while it was off the road for four plus years. As they were new I thought I’d try to look after them so I had them connected to a float charger, although I didn’t expect the truck to be off the road for so long and to be honest I don’t know how much longer they’ll last now.

I was ever so surprised when I found that the clock on the tachograph was right when I put the batteries back on!
