how can i fix my engine pre heat on my motor home,a fiat ducato 1995,2.5 td,seems to have failed completely,will not start from cold without excessive cranking of the engine?
Well check wether the relay sends 12v to the glow plugs when you put the ignition on..if it does you need glow plugs ,if it doesn't you may need a relay...or a means by which you can deliver 12v to the glow plugs....
