[QUOTE="TighterLeak, post: 8810234, member: 686585"] Hello, just wondering does Pio still use the Pico Fuse? I hooked my DA-160DAB (EU model) and got some whining (with even engine off), see the video. The weird thing is it reacts to pressure (as shown) so I doubt it's a pico fuse blown.. Also, seems to react to my hand position. I re-positioned some wires behind the HU and the whine gone away. Two questions: 1) If I measure the RCA shield to HU chassis resistance, does it tell me whether a fuse is blown? 2) If the picofuse indeed is blown, should I RMA the unit? It's new so it's got warranty.. thanx much [/QUOTE]
