sneach Posted June 7, 2009 Report Share Posted June 7, 2009 I had really bad alternator noise on my Z1, previous owner of my vehicle/z1 had shorted something on install and had put in the hack of grounding the rca wires, but I was still getting some static. I sent in my unit to Pioneer, they said there is a standard $200 repair fee for this model. I got the unit back pretty quick, i believe it was just under two weeks including shipping time. The problem was totally fixed and i undid the rca ground hack. The paperwork from Pioneer said the fix was just a fuse! (part number CEK1260). I looked up the part number on Pioneer's website and they list it for $8.50. I don't know how hard this fuse is to replace, or even what it looks like. I can't see any fuses on the external case, so I am sure this replacement requires opening the case. If you have the ground loop problem and are mechanically and/or electrically inclined, I would think its worth it to order this part and try to replace it yourself. Even though the part was listed at $8.50, I didn't get any of my $200 back. Quote Link to post Share on other sites
garrettoomey Posted June 8, 2009 Report Share Posted June 8, 2009 The Service manual shows fuse part number CEK1260 in 2 locations. I have attached a PDF showing the location of the 2 fuses. You can simply check for continuity across both fuses to see which one is blown and needs to be replaced. CEK1260.pdf Quote Link to post Share on other sites
03Aviator Posted June 11, 2009 Report Share Posted June 11, 2009 Garrett, are these fuses soldered in? Something tells me they are. This is a very common issue with Pioneer audio units...not just the Z. Go surfing some other forums and mention this problem and they all send you directly to a fuse replacement. Next time I order something from them, I'm going to get a couple of extras. Quote Link to post Share on other sites
garrettoomey Posted June 11, 2009 Report Share Posted June 11, 2009 Yes, they are soldered to the board... Quote Link to post Share on other sites
