I was just planning to go for a run in the Indy.

Turned ignition on, fuel pump primed, pressed starter then nothing. Ignition lights went off and now nothing. All electrics are dead, even those that should work without ignition, e.g. lights etc.

Checked all fuses, including the main 30a on starter relay. Got 12.6v at relay and at two of the connections on the other side of the relay.

Any thoughts?

Could it simply be the relay thats failed? Would this kill the other systems?

Thanks,

Check that your earth connection is clean and tight.

Could be slack or corroded battery terminals. What you describe is classic symptoms of a poor connection somewhere, ok until a large load eg starter is applied then complete failure.

Thanks for the feedback, will investigate further tonight.

Checked the points raised above, but still nothing.

The starter relay should not effect items with a permanent live.

Have you checked if you have +12v at fuse box?

You've not got an Fia batt isolator switch have you?
Has the battery failed catastrophically?

As above, start with the easiest thing to check! Battery

Bang a start charger or some jump leads onto it and see what happens

As above, start with the basics but....

Reminds me of a problem I had on my XR2 years ago. Similar symptoms but very intermittent.

Would start OK most of the time but sometimes would do the same as yours...ignition on but go to start it and completely die, nothing, dead, then eventually recover and start ok,. Would also die completely when you put the indicators on....not helpful on the unlit section of the M4 in Wales one night......

Eventually by chance, traced it to the main ignition feed crimp on the battery terminal. Not before taking the dashboard out, replacing the fuses, battery and cleaning all the earth connections.

Good luck, electrical faults on cars are a nightmare.....

Gents, as suggested above it turned out to be a kn*****ed battery. £20 for a new one and all is well.

Thanks,

Simon

Excellent result

Strange how we always jump to thinking its something more complicated from the off!!
I always do it,but it is nice then when you step back and think simple and its sorted

Excalent
Presume a bike battery hence my call
If so for interest how old?

Yes a bike battery, probably about two years old, I think this will be the third one in the seven years the car has been on the road.

Yes about right then, put my third on tho year, which is seven years.
Remember from my small bike days though use to put one on for every mot!
