As the GT's been off the road for a few months i needs jumpstarting with my other car now to start.

It does start instantly when jumping it with other car, and yesterday after switching it off it would switch on again 10 minutes later without being jumped, so battery level is low, but not completely flat.

To test and charge it i bought this Optimate 4, but i'm not sure if it's broken (got it off ebay, described as new, but package was a bit damaged) or if i'm being stupid and doing something wrong.

I connected it to the GT's battery, but all i get is a green light :


tried it with the crocodile clams laying down, and standing up

Reading through the manual it states it has 2 programs, so tried switching in between using the clams as stated, but again nothing happens.

Then hooked it up my other cars battery, which is fine and fully charged, but again nothing but a green light showing it's plugged into the mains. It doesn't test or check the battery or anything.




Looking on optimate's website i read this in the FAQ :

OptiMate will not charge my battery – no indicator lights other than the “power on” LED are showing. What is wrong?

"OptiMate will only start to charge when it detects that it is connected to a battery with at least 2 Volts in it. Either:
- The battery connection lead is not making a good connection to the battery.
- The in-line fuse in the connection lead has blown.
- The battery has less than 2 Volts.
If your battery is so badly discharged, or damaged, to the point where it has less than 2 Volts, it is probably irrecoverable."


Does it sound likely that that in-line fuse in the connection lead is blown or am i doing something wrong ?

So, why not check the fuse?

Optimate 4 is for small batteries (motobikes etc), even if do get it to start will take a very long time to charge your car battery.

This isn't helpful, but I recognise your one litre of Ecotec fury.

I have an older version and it charged the flat 100AH battery on my Land Rover just fine. Just left it on over night.

Take a look at this http://www.youtube.com/watch?v=ixz-iuOwFA0 turn it up LOUD!

Looks like your charger or the wiring is bust.

I couldn't see the fuse in the cable and didn't want to start breaking stuff if i have to send it back to ebay.
