decribe two causes of higher than normal starter current draw
No. There is an excessive current draw, possibly in the form of a short circuit. Get an electrician to check it and fix it before you set fire to house.
Locked rotor current is the amount of current a motor would draw if you energize the motor and the rotor (the spinning shaft) doesn't spin.

Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
Current draw and length.
Starter current draw refers to the amount of electrical current that an automotive starter motor consumes when it is activated to crank the engine. This current can vary widely, typically ranging from 100 to 300 amps for most vehicles, depending on the engine size and starter design. The high current draw is necessary to overcome the engine's inertia and initiate combustion. Prolonged or excessive current draw may indicate issues with the starter or battery.
When there is no current draw and the starter does not rotate, the cause could be a faulty ignition switch or a broken connection in the wiring that prevents power from reaching the starter. Additionally, a defective starter relay or solenoid may also prevent the starter from receiving voltage. Furthermore, a dead battery or poor battery connections can result in insufficient power to engage the starter. Lastly, if the starter motor itself is defective, it may fail to operate even if power is present.
Remove starter and bench test it for operation and current draw

The starter current draw test for a 2004 Pontiac Grand Prix involves measuring the current drawn by the starter motor during cranking. The specifications typically indicate that the starter should draw between 150 to 200 amps under standard conditions. To perform the test, use a clamp meter or ammeter connected in series with the starter circuit while cranking the engine. If the current exceeds the specified range, it may indicate a failing starter or electrical issues in the system.

Generally, you need a new one when the old one doesn't work properly. Oftentimes, a starter current draw test can be used to check for a bad starter.
Yes, but eventually your started will cease to work?
A typical starter motor draws around 50 to 150 amps while cranking an engine. If the current draw is significantly higher or lower, it may indicate a problem with the starter motor or the electrical system.
The wires to a starter motor are very large to accommodate the high current required to start the engine. During cranking, the starter motor can draw a significant amount of current, often exceeding 100 amps. Larger wires reduce the resistance and minimize voltage drop, ensuring that sufficient power reaches the motor for effective starting. Additionally, thicker wires help prevent overheating and potential damage during the high-current draw.
