Ok guys ive been asked to look at a mates recovery truck which has a few engine related issues, it has a 601.940 motor as far as i know

it seems the alternator isnt charging the battery, im getting no voltage increase across battery terminals once motor has started but it cranks over fine with a fully charged battery so i'd imagine the earthings ok to the block itself, i had a quick look at the alternaotr and it seems to have 3 relatively thin wires going to it (1 very thin and 2 slightly thicker - perhaps 16awg) anyone know if these are the main power outputs or should there be another wire attached somewhere thats perhaps missing?

Also the engine wont shut off on the key, i cant seem to find the fuel cutoff valve on the injector pump, is it electrical on this model? if so any tips on where its located

Its also a bit difficult to start, u need to plant the gas pedal to the floor and crank it over, after a fwe turns it will start and run at just above idle speed with the boot still floored then after 3-5secs it'll seem to clear and rev right up, it then wont idle on its own for a minute or so, im thinking perhaps one or more of the glowplugs is dead?

any help would be much appreciated

Cheers
