    Truck has been running great, new starter a year go. Always starting just by showing it the key even though standing in cold for a few weeks. Now suddenly i get this problem. I turn the key to position 2 all lights come on as should. When i turn to pos3 i get nothing. Not even a click. The amigos in the dash also goes off. Then bext time it starts normal. Sometimes it takes 3-4 tries before it starts. Symptoms are as if the solenoid to starter wire would be off plus the amigos go dim. Any ideas?

    so the wire is attached properly? Have you checked the wires on the ignition barrel?

    Yeah that is attached properly and even though that would be off the symbol lights should still not be going off. I wasvjust behind the dash trying to look for anything off but could not find anything that straight off would have caught my eye...

    Fuse or dodgy relay?

    Turn on the headlights too and if they go dim when you turn ignition to crank check the battery clamps to be well tigthened, if they are measure the voltage on the battery while you try to crank it without success(the dimming means that the circuit closes untill the solenoid but it doesnt engage for some reason)...if it's a serious drop give a tug to the solenoid with a hammer and if still no joy we'll speak again... how old is the battery ?

    The thing is that battery and alternator are 6months old only. I tried with head lights on, now with door open i could hear a click, headlights didnt go off, dimmed slightly for a moment as normally, the sybols stayed on. I will measure the battery and see what it gives. Could a worn out ignition lock cause this?

    Check that the back of your fuse board hasn't got a hot spot ....

    If he voltage doesnt drop measure voltage on the thin wire to the solenoid while cranking and if you get voltage the problem is the solenoid if no voltage swap the starter relay and if still no joy it can be a bad contact on that path, possibly like @Dippypud said ... if it was the ignition switch you should get no activity at all on crank position

    The battery had 13v when turned engine off, dropped to 12.2v when turned ignition on then climbed to 12.4v. Starting engine dropped it to 10.?. Engine running 14.2.

    this time it started straight off but the 10.? Seems low to me at crank.

    10V is a bit low it should not drop below 11V with a good battery but as long as i starts it's still OK... what AH and CCA is tha batery ?

    90ah 700a. Put it on charge now to see if it changes the situation. I could replace the starter relay also just in case. That would be the one in the box in front of the shift stick right?

    That's too weak battery for a Td5 from the beginning, never fit lower spec than it was factory fitted and that was 110AH 850CCA

    Previously i have been able to use these for up to 6-7 years/battery with hardly any maintainance. But lately i have been driving just around town short trips with no longer runs which could ofcourse drain it some. The weird thing it doesnt sound like a flat battery at all. It clicks from time to time, but when it cranks it does it like a fresh battery would. No sagging or slow spinning.

    Charged the battery full, since then it has nonstarted on me once. But when i measured again. Turning ignition on fully charged battery drops to 11.7V. Cranking dropped to 9.7V. Still started nice and all. But we are talking about a damaged battery here right? No grounding issues etc. should do this right?

    As i said, that battery is not up o the job from the beginning but when if it doesnt crank at all just clicks it's a problem on the soilenoid's circuit

    Ok. Solenoid and starter 6 month old but sure it could have gone bad. Might have to take that apart. Anyway ill replacevthe battery asvthis one gives way too values.

    It's not certain that it's the solenoid cos it's about the whole circuit... for a perfect diagnose you should hook a wire to the solenoid's spade connector long enough to bring in into the cabin and keep the voltmeter in sight connected to that and ground then watch it to see what happens when you get only the click and no crank... if you get above 10.5V on it when it doesnt crank the problem is the solenoid but if you dont get voltage then i'ts a bad contact on that path in the fusebox's connector or within the fusebox provided the relay is new and battery clamps well tightened.
