Electric fans burning out the fuses

[Gaz64]

Are these mini fuses?
I would be using a maxi fuses, and measuring the startup current.

ALL electric motors draw more current at startup, especially in a switched on/off scenario.

Resistance anywhere else in a motor circuit will LOWER overall current, and fan speed.
That's how we alter interior fan speed.
You can locate poor connections as a voltage drop test across each connection, and can be felt as heat in extreme cases.

On your DC motor, as the voltage drops (because of a bad connection) the motor current will increase (but the speed and torque will decrease). Now, I know you're going to look that up, and when you do, you have to come back and write "well, ok Pat you were right."
