I think your Starter Motor is shorted out!
Looking at the diagram the thick wire on the right of the diagram goes direct from Battery positive...no fuse...and on to the large lug on the Starter Motor.
When you turn the key the Starter Relay feeds fused +12 volts to the smaller lug on the Starter Motor ie. the Solenoid.
The solenoid pulls the thick red wire over to the left to supply unfused +12 Volts onto the Starter Motor. If this is a short to ground the thick red wire cannot blow as there is no fuse and the ignition gauges go crazy as you short out the battery!
This thick wire is able to handle this large current draw as it supplies about 700 Amps to turn the engine over but you will damage the battery if you do this too much!
You have to open the Starter Motor to be able to measure the coils/rotor for shorting as the Large Lug on the motor is floating until the solenoid pulls in and connects the thick red wire up!
Hope I am wrong but do the checks...this may have damaged something such as your door lock function!
