Electric Problems with Clock and Audio

Hey Guys,

got i little problem with my R33's Radio and clock electrics. A few days ago, my radio and defi gauges were powering on and off when i was driving. Yesterday they failed for good. So today i checked all fuses in the cabin, trunk and engine bay. All were good. Then i checked the constant voltage at my radio: 0 volts. Ignition voltage is working fine but the constant is gone. I just routed an extra cable from the engine bay to my dash for constant 12v and now its working somehow  Dont know where to look now. I'm out of ideas. Anyone got any ideas ?

Regards

Daniel

It sounds as though a connector may have worked its way loose.
Have a look behindbthe behind the dash at the original wiring. Find and connections and inspect/test them. A faulty connection should make itself obvious.
A multi-meter would be helpful for you here.

ps: if you still have a direct line to the battery, make sure you have a fuse inline.

Follow the 12v lead, starting from the radio, and measure before and after every connector, i thing there will be a deffective terminal, or a broken wire, which you will find if you follow the wire

[Dr. Surge]

Wiring diagram could be a nice help ()

[Warri]

I have a wiring diagram. It all leads to the fuse box in the driver cabin. Well guess i have to follow the one wire. Hope i dont have to rip apart my whole car

And are there connectors between

[Warri]

Cant tell from the diagram. Seems there are no connectors in between.

A possibility if a few things have failed is the relay on the fuse box, maybe try swapping each (there are a few) and see if the problem moves....

BTW your english is better than most people on this site at this time of year

There are two ACCs relays in the fuse box. But to they relay the constant 12v ? Haven't checked yet.

[Duncan]

When the key is at ACC or IGN they give 12v from the battery to all ACC fuses. So if fuses are OK and a couple of ACC things aren't working, they might be the problem

[Warri]

Earlier this day, i checked the fuse box contacts, where the RADIO Fuse is sitting, if i get there any kind of voltage. I pulled out the fuse andi got 12v on of the poles if the ignition is on. But thats not the constand 12v i'm looking for.

Try wiggling the key once its on. Unlikely due to how bad yours is but sometimes mine does this (AC cuts out also) but if i move the key around it comes back to life

[Dr. Surge]

Coudn't be a relay because he says he hasn't constant 12v, this one is not switched by relays normaly as it is a constant 12v.

Old thread, just in case it could help someone else I had a similar issue and the solution was to check the interior fuse box near the steering wheel. Check each fuse with a multimeter for the resistance /continuity, for me as 12V constant at the radio was not working due to  "ELECTRICS" 10A fuse being blown which is the 6th one from the top on the left.

I traced the wiring diagram and the Red/White wire  (+12V Battery constant) goes to this fuse.

Cheers
