Dead starter or immobilaser problem?

Hi fellow members,

Wonder wich of the above subject’s is causing me troble of getting my 1999 (X) started. Fuelpump OK,injectorsloom OK,
12,5 V on the starter. Starter is completly dead, no sound at all from it. Should there be a light wich confirm the starter immobilaser active?. There is no light illuminated in the dash. I can also mention that there is a aftermarket alarm/ central locking device mounted on it but I don’t think its connected to the immobilaser. But this aftermarket device is giving me headache as it activates the central locking every time I’m turning the ignition on. But this didn’t happend first time I tried started the engine, but became active after I disconnected the battery and charged it I thought that maybe low voltage was the problem. Any ideas anyone? -99 Td5 90 CSW

Measure with a multimeter. Then you know if you have 12 volts to the starter or not. It could be a dead starter or no power to the starter.

Check if you get 12V on the small wire when you turn the ignition in the start mode. If not it something else if you get 12 v there it is the starting motor. Take it apart, clean it, check the contactpoints and regrease the gearbox.

It will probably be the contact points but don't skip the rest. It isn't that difficult. If you manage to take it off the engine you can refurbish your starting engine too.

Hello,
Thanks for all advices. There is NO power to the small wire when ignition key is in the starting mode. So I guess it must be either the ignition itselves or the immobilisior. -99 Td5 90 CSW

If it is your starter you can easily repair it yourself. Common failure especially for a 1999, being so old... I had this happen to my 2000MY (built in 99). Kit is super cheap and takes about an hour to fix the burnt out solenoid contacts. Search this site for a step by step how to guide.

Good luck.

There is also a relay in the dashboard (with the fuses in the middle IIRC) that supplies power to the starter motor solenoid. That relay is energised by the ignition switch starter position with the earth side of the coil provided by the immobiliser. That's how the immobiliser stops you cranking the engine over.

If the relay is clicking when you turn the ignition to the start position then the immobiliser is OK. If it's clicking and you still don't get 12v to the starter solenoid (small wire) then check/swap out the relay.

The relay will have white/red wires connected to it. http://www.yorkshireoffroadclub.net/

Hello again fellow Defender owners

Thanks a lot of good advices.
Some update: It seems that it could be either the relay between the ignition and starter or the immobilasor. I do messure 12,5 V on the «30» pin on the relay but NO power on the 85(or was it the 86) when I’m turning the key to starting position.
I also messure 75 Ohm between 85-86. Is this correct? Is there any possibllity to overrun the immobilasor? How can I messure its wire and what reading should I get? The wire has the colour code: black/orange.
davew: the relay doesn’t click at all. -99 Td5 90 CSW

Hello,
Good news: problem solved

The problem was the control unit for the aftermarket alarm and central locking device. The white and red wire from the crank position on the ignition was going through the control unit wich is probably broken. So, I have disconnect the unit and cleaned out some other old sins wich has been used in the past with previous owners.
Thanks again for the good help and advices
