dc2r headunit not turning on

[marky53]

Ive got a pioneer headunit on my integra..... its only a couple years old.....

the other day when I started my car, the headunit didnt turn on at all, and my antenna didnt raise.... I turned the car off, started it again and it fixed itself.....

today (friday) it did the same, but after many restarts it wont come on. I have checked the radio clock fuse (one is under the dash and it was fine, the other was in the engine bay and it was blown, so I replaced it with a spare..... still no power to unit)

I also checked the aftermarket fuse that runs off the battery straight to the headunit and thats fine.....

I pulled the unit out, checked the earth and power lead all seem to be fine.... then I disconnected the battery and still no power to headunit.....

Does anyone have any other suggestions as to what I might be able to check???? Surely the headunit has shit itself already???

check the remote wire to see if it's loose/disconnected.

when I pulled the unit out, checked all the wires and they were still wrapped in electrical tape..... should I pull all the tape off and check each one individually????

could be a long shot but maybe the fuse on the headunit itself?

marky53 disconnect the female plug that clips behind the stereo and grab a test light and check if you have power coming from the red and yellow wires, this is the easiest way to check if you have a wiring loom or fuse problem. If you do have power coming out them then you definetely know that your stereo has sh*t it self.

Tested the yellow and red wires..... Red (acc) lit up but nothing on yellow (batt).....

Also, the tester lit up when I hit the red lead running from the positive to that big fuse on top of the battery.... however, the cable running out the other end of the fuse (is the yellow battery wire that runs to the loom) is not lighting up...... so do I need to replace that fuse, or the cable coming out the left of the fuse????

ps - the fuse appears to be intact and does not appear to be broken in any way.

update.... changed the 60 A fuse on top of the battery and head unit fired up straight away....

lesson for today is that even though a fuse appears to be in good condition and intact, it may be the reason power is not getting through...... case closed.....
