The bulb with the lowest resistance. Current = Volts / Resistance
When testing the current draw your digital multimeter should be set on the current.
As well as motors, contactors also have kW and Ampere ratings. Have a look on the name plate of your motor and you will see its maximum current draw (amps). Select a contactor with a current rating greater than this.
all electric heaters draw a lot of current (voltage times current = watts [or power]) and a toaster heats bread (no it toasts Bread)
for smooth operation and also to reduse starting current
decribe two causes of higher than normal starter current draw
Remove starter and bench test it for operation and current draw
25amps
Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit? Over load in circuit? Remove starter and have it checked at auto parts for excessive current draw Dead short to ground in circuit?
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.

The starter on the Sprinter has a Solenoid on the starter. That is the closest thing to a starter relay. When you turn the key, current is sent to the starter solenoid which pulls in and completes a current path to the starter windings.
Starter relay protects the ignition switch from excessive electrical draw.
