T7 worklights

[Fubar]

All the lights apart from headlights have stopped working on t7. Checked fuses and relay that I know of. Am I missing something?

T7 where I work had that problem with all the lights on the front of the bonet, shook the loom between the cab and the bonet where the bonet hinges and the lights came back to work. Slightly different issue to yours maybe but it might help??

Thanks. We haven't even got tail lights. Just head and dip. The battery has been playing up lately. Won't start after sitting for a couple of days. Had to jump it yesterday. Tested it a week ago and was told it was fine. Wonder if something may be draining it. Wonder if it is all linked?

It’s your park light fuse

No park lights = no work lights

When you look from the off side door it’s about 4 rows down and I think first and second fuse in from the left. There are two of them

What @benferg said, if they blow a sidelight fuse you lose work lights

Thanks. It was the fuses with a p which I assume means parklight. Driver had only checked the fuses and relay linked to worklights.

Glad you had success ??

You’ve got a fault with a trailer or something that uses the 7 pin plug most probably if it’s blown the sidelight fuses. Jump starting shouldn’t blow them but can blow much worse things with voltage surge from the alternator. Be careful using jumpleads and boosters on such vehicles.

So are you saying it's not safe to jump start a t7?

It's not ideal on anything these days with all the electronics, I always turn the headlights on so they will absorb any spike.

Good call on the fuses, we've had the same issue with work lights.

Starting a T6/T7 on a low voltage can cause the ECU to lose it's rear lift calibration. According to the local dealer it's a common issue.
