Hi Guys n girls
I have a Mk4 autosleeper camper van. originally 2.0l petrol bu the previous owner has installed a 2.5l TD form a Mk5. When shes started she runs fine until i pull up and turn the engine off to re fuel etc then it struggles to turn over and start !! if i drop the jump leads onto the leisure battery she fires up. ive had a new battery new alternator new starter motor but problem still persists.
Also when stood over the winter period its a nightmare to get started ready for summer season. I have charged both the van batteries over night and bought a 87amp lorry battery from scrap yard to jump from but hardly even turning over. Cable to the starter is getting hot when trying too
Any ideas at where to start ?
