That's unfortunate about your install. I ordered some replacement fuses from console 5. I'll update once I get the fuse replaced.I'm kinda stuck right now with this project.
I was able to get my hands on replacement parts but I have really botched the install beyond the fuse. I'm not even sure if they were ever bad. I may have had some bridging. So I'm waiting on getting a suitable replacement PS1 so I could attempt the install again. If you cant get continuity i think you have to replace it.
