A.R.C. Ignition System
« on: Mar 08, 2011, 16:19:08 »
Have a 77' Honda CB400f and this was under the seat.
 
Can someone tell me how it fits into the wiring diagram i have here?

Does no one know what this is and how it fits in, or are you ignoring me cuz i dont know something completely obvious.

Where do those 3 wires go / come from?

Looks like a transistorized ignition from a while ago.

My guess is if you look at your points plate you will find a hall effect sensor rather than points.

Wires into the box are likely ignition hot, ground, sensor wire(s), and coil hot(s).

trace the wires coming out of the box and see where they go.

A modern equivalent would be a Dyna electronic ignition.

That's my guess.

All opinions worth less than $.02 with inflation, but still worth more than you paid for it!

Cheers.

Big... thanks for the reply...  I a going into the garage in about an hour and going to try and take some detailed pictures of the ARC Ignition thing.  I believe one wire is going to the Black with white trace, one to ground, and one... i dunno but will post what i find

I'm guessing it's an ignition booster. Prevents arcing at the points.

If it's transistorized it most likely still has points. Those boxes usually take the place of the condensers. Pretty much just stabilizes and boosts the spark while still using the points basically as on off switches.. I have the hondaman version. Works great. Mind you, I'm not exactly sure that's what it is but I agree with Bozz that that's what it looks like.

Yeah... my points dont look like stock....   Here are some pics of the current set up.  You can see the red wire on top is actually the black with white trace that comes from the ignition coils, then we have another black with white trace that i dont know where it goes (diagram shows goes to "main switch" and splices with a brown wire and goes nowhere <~~~ what does that mean?), and finally we have a ground.


I am just guessing here, but i think the green should go to ground, the red should go to ignition coils, and black should go to main switch?  sound right? 


thanks for any input you guys can give as i have tried a few combinations with no luck.... maybe i screwed something up somewhere else?

That box is a transistor assisted ignition I think - as someone mentioned earlier. They don't do a whole lot, but they do extend points life.

Ignition wiring is usually 12V to main switch to Kill switch to coils to points and Condensors and through the points to ground.

Transistor switching is wired differently.  You could try removing the box and wire as per stock and see if that works.
