Sounds like the terminals aren't on the batt properly or the batt is flat.

battery isn't flat and checked the terminals three times

100% sure the terminals were re-connected the right way round. Does your Nav have a main fuse on the +ve terminal ? I seem to recall there being a main fuse somewhere around the battery, either on the terminal itself or underneath the battery somewhere.

One way to know if you have power reaching everything it should is to pull one of the fuses in the fuse box (any fuse in any fuse box) and check with a multimeter between any ground point and one side of the fuse base to make sure there is 12V present.

 

[shanea]

yes the terminals are on the right way and have already checked if the fuses are getting power and there is 12 volt present. Don't know what to try next thanks

Check and clean the earth fom the battery to the body.

Just checked the earth and cleaned it but still nothing happened

Does the engine crank over at all?

How many squeezes before your fuel primer goes firm?

I'd start by removing the terminals again and giving both the posts on the battery and terminals on the cables a really good clean with a wire brush. You can get ones specifically for cleaning battery terminals. Then try again. Sounds like there is power there but it isn't a good connection so as soon as you turn the key on and the glow system tries to start, one of the battery terminals arcs out and breaks the connection.

The battery may show 12 volts but may not have enough grunt to turn it over. Just a thought.

Yep, as above, hold your multimeter on the terminals while someone tries to crank the engine.

If the voltage stays constant, then you need to look at relays / fuses because the ignition is not trying to start the car. (i.e. the battery is not being loaded by the starter motor)

If the voltage plummets, then the battery is dead.

No it doesn't crank over at all nothing happens no lights no horn no radio etc but it is
getting power checked with the multimeter. Is really strange and cant work out why and frustrating. I will check the fuel primer when i get home

 

[happy john]

I would give it a go with another battery, I suspect yours has shit itself. Maby a collapsed cell or something....

 

[Old.Tony]

If there are no lights or anything then check the main fuse and main cables again. Try a replacement battery (borrow a mate's for a moment, but don't forget to put a small battery across his terminals to keep his radio PIN intact).

Can we step back a minute, why did you disconnect the battery ? Did you do any work to the car with the battery disconnected ?

Hey guys thanks all for the help, has been resolved it was the ignition switch, there was power going in but no power going out.

Awesome, that's a tricky one.
