I am installing a CD / radio head unit in a 1992 Landcruiser 80, and am having difficulties locating the constant power wire. The workshop manual shows it as blue yellow, which I have located, but there is no current. The ignition wire is delivering current when switched to accessory. I have tested all other local wires (which the previous owner had cut removing the old head unit) and there is no current available in those either, so I am pretty confident the blue yellow wire is the correct one.

There does not seem to be a fuse for this circuit, but maybe I have missed something, or it is shared with another circuit?

On an aside, there doesn't seem to be any power flowing through my interior lights either - once again, no dedicated fuse.

Any suggestions?

Cheers

Gday,

I've wired my share of stereos and amps into vehicles, but im not familiar with 80 Series per se.

Double check ALL fuses in the main panel as a start.

You will usually find a constant power source at the back of the factory dash clock (as it has to keep doing what it does while the car is off..)

A constant source is usually easily tapped off this if u cant locate one at the head unit wiring harness. This will be fine for the head unit as its not powering the unit, only holding memory etc, of programmed radio stations, keeping the head unit clock going etc.

depending on where the clock is located (and ease of accessibility etc)...this may or may not be helpful, but its always worked for me.

Regards

Rev

It would be a safe assumption to presume that there is a fuse, Mr Toyota wouldnt wire this up with out one. Check the fuses with an Ohm meter. Sometimes (especially the glass one) can look OK but they are broken at the end where you cant see them clearly.

There is an always on wire in the wipers if you really get stuck and have to start from scratch.

Johnny,
Acccording to my wireing diagram there appears to be a fuse marked "Dome" which is a 10amp fuse. This is situated in the fuse box on the passenger side of engine bay and is in the bottom right hand corner. This also controls the interior lights. Hope this helps.

Thanks guys, the fuse marked 'dome' was the offender.

And after powering up, I now find there is a CD is stuck in the head unit! Which is probably the real reason the prior owner removed it from the car...

I bet the dome also supplied the duke box untill the previous owner shorted it out when he cut through the wires all together....
