I am restoring a nice Sears Soundstage II standard 8mm magnetic sound projector but am not an electrician. Runs smooth and quiet, but all 8 of the wires in the wire harness have been taken off their "tabs" in the back speaker chamber. They are clean and intact, but I have no way of knowing where to put them back. Any one have ideas where I can turn?

Hi John,

-It's a pleasure to have a member from the Great State that gave the world Blackhawk Films!

Technically I'm not an electrician either, but I wish I could help you here!

(I'm an Electrical Engineer. What's the difference? I spend a lot more time unemployed! Career total now stands at more than a year!)

Eight wires! That's a lot! Can you identify the eight places they should be going?

-Maybe we can thin the herd a little.

Thank you for writing! This is the first blog site i have ever tried and it is like having other friends and hobbyists to talk to. i am will try to learn how to upload pictures and send you what I am dealing with.

Hi John,

The picture upload here is kind of famous for being...challenging, but learning to do it is a rite of passage here. (It's OK to ask for help early on.)

I've been pondering your dilemma and I'm wondering if maybe your wires are color coded something like this:

Brown
Red
Orange
Yellow
Green
Blue
Violet
Gray

There is this downright evil thing I had to learn in the very beginning of Elementary Electricity back in the ninth grade called the resistor color code.

-Once again: this is a rite of passage. If it gave the kid a nervous breakdown they sent him back to wood shop. Those who managed to absorb the impact were on a track that could lead to Engineering School, or maybe even TV and Radio Repair!

("-and now I am the ruler of the Queen's Nay-Vee!")

It's not that it's particularly that bad for those of clear mind, it's just dumping something this confusing on somebody who's also coping with adolescence...

These colors in sequence stand for 1,2,3,4,5,6,7 and 8.

Often this code is applied to other things than just resistors.

-just maybe!

There are many rhymes to help remember resistor colour codes. At the Royal Air Force's Number 1 Radio School in 1953 I was taught:-

Billy Brown Revives On Your Gin But Prefers Good Whiskey.

Black. Brown. Red. Orange. Yellow. Green. Blue. Purple. Grey. White.

0.1.2.3.4.5.6.7.8.9.

It's amazing what you remember after all these years. I also remember my RAF service number !!

Yes,

In high school we had "Bad beagles raid our yellow garbage...", but the ones I heard in industry aren't suitable for general (-or maybe ANY) audiences! ("...but Violet gives willingly." [Eek!] )

What's funny is first they put us through this, and once our heads stopped spinning they actually taught us Ohm's Law so we had the slightest idea what an "Ohm" actually was!

(-at age 14 and earlier, my electronic theory was mostly instinctive. That my parent's house is still standing is kind of a miracle!)

Big Bald Ronnie Wore Yellow Grundies, But Mavis Grabbed White!

That's how my mate and I remembered it from 2nd year High School Physics lessons. [Big Grin] [Big Grin]

You may think this makes no sense, and you'd be right, except to say Purple was described to us as the colour Mauve, and wore for Orange? well it fit with ORE from wORE and we always remembered it meant Orange and low and behold...still do!

Neil Herbert will remember this also, quite a giggle when you're aged 11/ 12! [Big Grin] [Wink]

The above brings back memories from my stint in electronics factories a few years short of 50 years ago now. As regards resistors, the third band was the multiplier. So, brown, black and brown meant that it was an 100 ohm resistor. When resistors overheat, the bands can change colour so that red can look like brown for instance.
