Last year when I purchased my boat, a 2006 Centurion Enzo, I had the a perfect pass installed on the far right of the dash where the blank is or was. Well the installer apparently took those 4 hot wires and taped them together and stuffed them back in the dash. Couple of times last year while we were out, I could occasionally smell what I knew was an electrical fire, but thought that it was my switches that I run my ballast pumps through. I was not using a relay and the pumps pulled just about as many amps as the switch was rated to handle. I just assumed that the switches were failing and was planning on addressing it next spring. Well now it is next spring I have been spending some time cleaning up the horrible wire runs from the perfect pass install and in doing so I came across the source of what I am pretty sure is the source of my electrical fire smell. It appears that the wiring wore through the tap or the tape came off and the wire was contacting the metal brackets that holds the gauge into the dash panel. You can be the judge by looking at the attached pictures.
Anyways, my question is what do I do with these wires and how do I properly and safely dress them to prevent a future catastrophe?
