Radio power supply fuses

[l10tus]

Upon checking the S.H.Bible, I can't locate the fuse / relay? position for the Radio supply, can someone point me in the right direction, as I don't have 12vto any wires at the radio, help / direction / education as ever, greatly appreciated.
Cheers,
Phil.

Hi again. It's worth going through all the fuses on the board. When I replaced the old veneered radio cassette with a modern unit I had to rewire the original plug so the feeds and negative married up to new iso connector. You should have 3 feeds, one battery feed, one ignition feed and 12v feed from the panel light circuit to light the head unit up with the lights on. The other wires in the iso connector are outputs ie, amp/electric aerial etc. Regards.

Get yourself a test lamp with pointy end, you can probe either side of the fuses without removing to check for power.
Can be easier than pulling every fuse in tricky locations.
I would guess it was on the clock or dash lights fuse but it's not one that's marked.

Thanks for the replies gents.

Thought the supply may be to the "dashboard" fuses as there's not one listed for the radio on its own.

However, I have a working clock and panel lights, so I guess that excludes that circuit, it's an early car 1994, so we're there any other circuits employed??

Looks like a manual trawl through the wires back to the fuse board, methinks?

Reading in the bible it says early car radios were always live without the ignition being turned on??

Hi. Mine was like that. The battery positive was linked to the ignition positive behind the radio so it worked without the key in the ignition so I separated mine and made them independent. Regarding drawings I've looked at the bible schematic and there's no dashboard wiring so it was probably on a cigarette packet thrown out in 2007. If your feeds are missing I'm afraid it's time to get the multimeter out. I would guess the ICE loom is spliced into the main loom piggybacked off other fuses. I would suggest the ICE loom is fitted when the main harness goes in and is independent from the dash loom. Dash looms are usually fitted to the dash on a sub assembly.

Thanks for the heads up on this. It'll give me something to do though!
