[Defender 90 not starting]

Thanks all - bit the bullet and bought a new battery.

Now it will start if i short out the starter / solenoid but not on the key .. its almost as if theres not quite enough power to start it ... so new solenoid im guessing now ?

Thanks again for the help

No it wont start on the key with a jump.

Ive cleaned the contacts and it made no difference .

 

But I appreciate the ideas  thanks

I have a 1987 exMOD 90 with a 2.5 diesel .

Lockdown meant it hasnt been driven and when I came to fire it up not much happened....

I can hear a click (presumably the starter solenoid), when I put another battery pack onto to the existing battery and short the starter I manage to get it to start however its not a lasting solution or ideal for supermarket car parks.

The battery shows 12.84V after charging but once used to attempt to start (and failing) it drops to 9.4V .

Is this as simple as a new battery or should I be testing for something else as well ?

Any advice gratefully received.
