Dolphin Diagnostic just shut off

We have had this for about 10 years and have never had a problem (other than it getting stuck on the main drain).

Yesterday, we put it in the pool and turned it on and it ran for about 20 feet and then stopped. I noticed that the switch light was out. Would this be a blown fuse or would the switch be bad? I removed the switch but haven't bought a new one yet. Will buy a fuse today and try that.

Where is the fuse located?

Thanks
