1st time poster so go easy

Here’s my problem.
So as I was driving my radar detector showed over voltage and shut down, turned back on and everything seemed fine until it did it again and that’s when I noticed my dash lights getting brighter. Once I got home I disconnected the battery to see if it was the alternator and when I did that it stayed running, but then all of sudden my wipers started moving and then it died and would not start again. After doing some troubleshooting I discovered that during that time it blew the efi fuse, fuse in the back of the radio and burned out the cab light as well.
The EFI fuse blows as soon as I turn the ignition on.
I’ve checked the EFI relay and it’s working properly.
I know that relay goes to many places, so seeing if any of yall have had this issue. Thanks
