Help Please - ? Broken Solenoid

Hi All,

Currently on my trip around Norway, so far made it to Levanger, but have had some problems....

This morning the car refused to start coming off the ferry, it was bump started and since has run with no problems, stopping and starting on the button for around 600 miles today.

However, getting into camp tonight the car refuses to start again once stopped.

I believe it is the solenoid on the starter:

- There is a good main 12V supply to the starter
- When turning the key the starter relay (under drivers seat) works fine and gives a good 12V output, this is mirrored on the switched input of the back of the starter with no obvious V drop between relay and solenoid.
- Although there is a good 12V supply, and a good 12V supply to the starting wire when turning the key, there is no 'click' and there is no 12V on the solenoid O/P cable with the key turned.
- Shorting between the main 12V supply and the solenoid O/P when turning the key starts the car no problems.

So, first, do you think my diagnosis is accurate?
Is this known to be a common issue at all?
Is there a fix beyond replacing the whole starter than I will be able to get sorted whilst still here? Any part no.s would be useful!

Thanks all in advance!

hi Kris

I'd start by checking all the relays are seated properly and dry

what sort of temperatures are you in at the moment, how about warming the start up with a blow torch ?

Hi Steve,

All relevant relays cleaned, and re-seated but were working as they should prior to cleaning them.

Temp is only about -5 at the moment and this began on the ferry when temp was still in the plus (+4ish...) but will give it a go.

Alternatively, does anyone know the ford part no. for this alternator? There are a lot more Ford dealers than LR here!

Phoenix, if you can't hear the click from the solenoid it's probably just stuck. Get a suitable length of wood someone to turn the ignition switch and give the solenoid a good tap. As your on the road at the moment taking the solenoid out and greasing it isn't an option.

did the tapping work, sounds like a sticking solenoid. Cheers

I once experienced that, though there seemed to be a 12V supply on the relay on the starter motor, there was some resistance in the supply wire to this relay. As a temporary "repair" I installed another relay in between, so the original relay on the starter motor got a new supply now directly from the battery via a new thick cable. The helping relay is activated by the original supply wire. This wire had enough current for activating the helping relay, but not for activating the original starter motor relay.

Sounds a bit fuzzy, but hope you understand what I mean ...

Thanks for all the suggestions guys.

In the end I took all the cables off (what a

of a job that was in -3!) cleaned them, re-applied to the starter and it it has been fine since.

I think the Solenoid o/p cable nut was loose when I took it off which may explain the issue!

Fingers crossed for the rest of the trip!
