Master Terminal 30 Interrupted

I've got a 2022 Renault Master diesel, and it's giving me grief. It's done 103438 km. Seems like Terminal 30 (continuous plus) is interrupted. Cranks real slow, barely starts. Almost like a flat battery, but everything should be okay. Any ideas?

Sounds familiar! Had a similar headache with my old Peugeot 308. Same symptoms, slow start, felt like the battery was knackered. Have you checked for any parasitic draws? Could be something is draining your battery while it's parked up.

Parasitic draw, eh? How would I go about checking that? Is it like leaving a light on in the fridge?

Exactly, like a fridge light staying on! I didn't have the gear to check it myself, so I took it to a workshop. Turned out to be a short in the wiring harness. I'd suggest getting it checked out; electrical gremlins are a pain.

Thanks for the advice. Took it to a shop, and you were spot on! They found a faulty connection causing a drain. New wiring section sorted it, cost me 290€. Appreciate the help!
