iveco tector 75e17 starting issues

[m3vuv]

Hi all,i have a 2001 iveco cargo tector 75e17 4cyl 4ltr,this has a starting issue,you have to hold the key in the crank position for 6 seconds before it will crank,but on the buttons under the cab crank it cranks over strait away!,now and then it wont recognise the key and then it wont crank off of the key or buttons ,batterys are new and charged,the customer told me the cab tilt lamp was on so he took the bulb out,the cab switch/sensor has 3 wires so am i correct in thinking its a hall efect device?,im thinking this is an inhibitor issue with the cab tilt sensor?,also the starter seems to have two solenoids on it,the normal one and one about 50mm by 30mm,any ideas what this does?,i could use a wiring diagram for this and any info on the edc flash codes,can anyone shed any light on this?,cheers Paul m3vuv

Hi
Only going of experience here. The two solenoids on the starter - I take it one is smaller than the other. That one will be a slave solenoid to the larger one. Does the starter start every time of you bridge out the solenoid?
