Clicking from speedo/motor?? Any ideas?

[gazhillAE]

Hi guys

Just cleaned all car after run on Sunday.
Put it back together and it ran fine and then tried again and the following happened.

When you switched the car on theeee was a loud clicking sound which seemed to look like the 4wd drivetrain had locked up.

The motor would not move at all.
And the motor was vibrating every time the click happened.

Also the positive battery wire was extremely hot??

Any ideas??

Now all I'm getting is three flashing lights on the speedo and that's it!
Steering works fine but no power to the motor etc

I've got a video of anyone wants it emailing to them
I'm puzzeled
