DIY Pico fuse question

[Heeltoeclutch 10+ year member]

Sooo my pico fuse got toasted when a chitty zip-tie came undone and let loose the RCAs under the seat. The seat moved back and ripped one of the RCA cords from its plug! Pop. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Right now I have my RCAs grounded to the HU, but I would be more comfortable if there were some sort of fuse in there. I have two extra 16-ish gauge blade-type (ATC?) inline fuseholders lying around, and so had the idea to ground the RCAs using the fuseholder. My question is, what size fuse should I put in there? The HU is a Pioneer 4300DVD. I'm wondering if they even make ATC fuses small enough to approximately equal the pico fuse; might have to run to radioshack and get a glass (AGU?) fuseholder. Anyone have any idea?

Thanks! //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Take the unit apart and put a dot of solder on the PICO fuse and then you wont have any issues. There is a tutorial around here some where.

What I'm worried about is jumper-ing a fused circuit... //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif what happens if someone or something causes another hotswap beyond my control? HU goes boom cuz no fused protection?

It is not a fuse, but a diode. Pioneer tech support says that it is not replaceable with any other diode or fuse. You need the exact diode.

According to all the threads and pics I've seen it's a resistor...? never ripped it apart myself.

If it weren't still under warranty I'd probly just fix it myself, but for now I'm gonna have to just ground the RCAs. It's almost entirely gone with them grounded.

I'd just drop a dot of solder in there eventually if I were you. That's what I plan on doing should I ever blow the pico fuse in my 800PRS. I take great care to ensure I don't, but you never know, as in your case.
