I bought an Aiwa ADC-M65 used, with no manual. I found a PDF manual online, but it doesn’t say anything about wiring. Red and black wires are pretty obvious, but there’s a third yellow wire, with a 2A inline fuse, and what looks to my untutored eye like a small transformer. It looks like a small cubic spool of wire, with white ends on the spool. The wire is covered by yellow tape or something. I seem to remember once hooking up a car stereo where the yellow wire was constant power, to save the preset stations and such. Is that a convention? Should this yellow wire go to the constant power source? Should I just look for another yellow wire coming from the stereo and hook it into that? The ends of the red and yellow wires are twisted together as if they were originally connected to the same thing - if I can’t find a yellow wire, should I connect them both to red?
Thanks for any help.
Since the yellow wire has the fuse and the choke (I’m guessing that the spool of wire thing is a choke, which is what it sounds like from here without actually seeing it), I’m guessing that the yellow wire is the main power (switched) and the red would be the constant battery wire for the memory backup.
I wouldn’t think you would need the heavy duty filtering and the fault protection on the memory line, but then again I didn’t design the thing.
If you don’t know how to wire to a constant battery source and a switched accessory source then I strongly suggest taking the thing to someone with a bit more experience. The only thing standard about auto wiring colors is that there’s no standard. Connecting wires together just because they are yellow is a good way to make smoke.
More information:
According to Aiwa, their CD changers “conform to the ISO wire color code standard”. Also, these wires are going to an FM modulator (model RF-M60), which I should have mentioned before. If I can’t get solid info on the yellow wire, I’ll take it to a shop, but I’d much prefer to do it on my own.
