I have a Jcb fork lift 930 rough terrain model with a 4 cyl diesel and intermittent no start especially cold will crank but the transfer pump (mounted on the fire wall) will only operate when 12 volt jumper directly to the pump to reprime it bypassing a relay? Disconnecting the jumper after it starts works just fine,any thoughts do I need a wiring diagram or is the relay wired incorrectly,thanks roger
