Have a 1.3 multijet 09 Doblo, runs perfectly all day. Last night when engine was switched off, it would not start again a few mins later. Nothing on the dash and switching headlights on, they were very dim. i got a jump start an it took me 2 miles home. Started straight off this morning, and used delivering all day without a problem until tonight when using headlights, after stopping it repeated last nights performance. after short while it started again then on way home cut out again. luckily this time on a hill so bumped it an got home. Any ideas???
As I have said only seems to be happening when lights r being used at night. Checked battery and alt. no probs. A reply asap would be appreciated, Thanks.
