My new radio requires two power connections, one fused and continuous (for the memory presets, etc.) and another that powers up only with the key on.

My ignition switch has no continuous current spades left open. I think the blue/brown is hot, and that one switches out to the solenoid via the white/red, if I recall correctly.

What is the best way find a continuous 12 volt current for my radio? Can I just tap off the voltage regulator or will that fluctuate or cause other problems?

Admittedly, I'm no genius on auto electrical. Thanks for the help.
 
Sure, the A1 terminal on the control box will do fine (which is where that brown/blue wire goes).

I even added a Lucas fuse box powered from that terminal, since I had several other things that I wanted to have fused, continuous power.

I also added a fuse box -- just a second one identical to the one already on a TR4 but located under dash to the right of the radio. Used it for the radio and the 'cigarette lighter' outlet.
 
Great, thanks!

On the radio issue, any thought as to whether static is likely to interfere more or less depending on whether I take off from the A1?
 
Nah, I doubt it will make any difference at all.

If you do have problems with static, IMO it is more likely to be RFI through the air, rather than conducted on the power lead. Last time I had a problem (with a CB radio), adding a 0.1mfd ceramic capacitor right at the generator output terminal to the housing (one of the through-bolts as I recall) made a big difference.

But if it is coming through the power lead, it's easy enough to add a filter to that as well. Here's an example:

Hey, I got my new Moss "Retro Sound" radio installed. I'll follow with a pic soon. It went in really tight and neat, and it sounds great.

I learned something new in the process. Speakers must be mounted in one of several ways, and one of those is to encase them in a wooden box. I made one that fits up under the passenger foot well. I have two stereo speakers up there, but they can't be seen, and the outward appearance of the radio is quite good, though, of course, the dial doesn't say "Triumph."

I have an extra Triumph radio I'll probably put on Ebay. It feels good being able to listen to both AM and FM, with quality sound, and to still have an old fashioned antennae.

That plus my overdrive rebuild makes me think about a trip somewhere soon. A long one.

Oh, and by the way, Randall--I took the hot right off the VR like you said. Works great. No static.
