my mate is now putting his rs turbo van on the road, it was running the other nite, went to go start it the next day and it was dead. there is no power from the battray, its a new battray and the earths look gd, sometimes when u push the hazard button in it'l flash once and just go's out again, or it will stay on but its very dull. he has tried puttin a jump pack on it still nothing.

Any Advice?

 

so the battery has power?
have you ried runing every appliance lights heqaters etc if nothing i wud run it to the power wire from the battery to the started make sure thats got power goin thru it if not its the battery
just make sure every things bolted up properly as a loose starter wire and the car will be dead also try the battery connections aswell

 

He has got it sorted now, it was a loose wire, not sure what wire it is but its sorted now tho.

cheers mate
