Obviously you did not verify the power supply which is where you should
have started when diagnosing a blown fuse. It looks like from you
information that you have tried several fuses. Time to call on someone
who knows what they are doing and has a basic understanding of proper
troubleshooting technique to have a go at the set, in person.

You may need to have someone who has more experience working in your
shop give you a hand with the repair and help to bring you up to speed
on troubleshooting and repair.

Continuously replacing a blown fuse is not proper troubleshooting.
