I've got a bench top 12 volt power supply, which is putting out 13.7 volts. I am trying to power a 12 volt marine blower fan. When I power it up it won't spin unless I start it with my finger. The same fan on a 12 volt battery spins instantly.
What's going on? Is it an amperage issue? The power supply is supposedly rated to 9 amps, the fan draws 4 amps.
