Car getting NO power. Jump leads caught on fire! HELP NEEDED!

Re-shelling my Glanza at the moment and have everything in. Engine and all interior.

As soon as I turn the key there is as if there is no battery in the car.

Not even the clock or radio will come on.

I tried changing ignition barrel and it made no difference.

I also changed ECU.

I changed the coil and ignitor.

I changed the connection on the alternator as the old one was melted.

I took off the earth for the alternator and made sure there was a good connection.

I also took off the earth for the starter motor and made sure there was a good connection.

I also made sure the connection is on the starter properly.

I changed the battery as it was gone dead and now this one has gone dead aswell?

I was thinking it was the 100A alternator fuse but we changed that before we started and it looks ok now.

I looked behind the ignition barrel to see if any wiring was cut or anything but all that was there was the wiring for an old turbo timer. I plugged that out and plugged the original wiring back in.

Absolutely baffled at the moment.

I'm leaning towards ignition problem.

I checked all the earths and they're all perfect, put jump leads on then and nothing.

Went then to take them off and they nearly caught fire!!

As soon as I connect up a good charged battery there is a big spark and it goes dead after a few seconds.

Can anyone shed some light on this for me please.

Thanks.

Earth on the alternator and and starter sounds suspect as they are meant to be live feeds, not ground connections!!!

Something is majorly a miss somewhere. But its also probably something quite simple!

Never knew they were a live? But they're bolted down good and tight. Where do they get there feeds from?

Need to know did anyone run in to this problem before.

Nearly going to give up at this stage.

Are you 100% sure the battery has been connected up the right way, and not negative to positive?

Sounds to me like something's wrong way round. Hopefully something simple. Are you sure you havnt crossed ur terminals or anything

Yup even changed for a good battery, I disconnected two connectors down by the ecu to isolate the problem, also disconnected one in the fuse box by the engine bay. Connected the two inside ones up and the alternator fuse blew.

have alternator and starter disconnected at the moment to look at the loom to see if any of it's melted but it was perfect.
I'll get pics in a bit.

If you are getting enough current to nearly set the jump leads on fire and blow the alt fuse you can forget about the small stuff like the ecu. You must have shorted a bigger wire to earth somewhere, or connected one to earth by mistake. Check the loom where it goes across the top of the gearbox and behind the block below the inlet manifold, disconnect it from the alternator and starter and pull it back towards the gearbox to check the underside of it as well.

you sure you connected the live wire at the positive terminal? one goes to the starter and the other to the auxiliary. Check the Main fuse. it must be blown.

Could alternator be f*cked? I disconnected the alternator and starter motor today and pulled them back and there's no cut wires or anything? Could alternator be f*cked?

If you disconnect the alt wires and tape them up, replace all the fuses blown and connect the battery, if there is no other faults then the starter should run. Did you use the matching interior loom and engine bay loom or is it a mix and match from the 2 shells?

Sorry never replied, not online much, turns out the live wire on the alternator was slightly bent and earthing off the alternator itself!
