<!--EZCODE EMOTICON START :hat --><img src=http://www.ezboard.com/images/emoticons/pimp.gif ALT=":hat"><!--EZCODE EMOTICON END--> <br>Hello from a rookie and congratulations on a great forum.<br><br>I am building a real bitsa: 750 frame 1000 engine etc. What I need help with is understanding the functionality of the 3GM Ign box and the large relay that appears to link such things as the clutch switch to the Ign box. I have a Haynes manual which does not show what the inner workings are or logic diagams or functionality per pin position.<br> I hope this makes some sense !<br><br>Can any one help out here ? <p></p><i></i>

Welcome golgother, I understand what you'r asking for, I think, and unfortunately, It's hard to get that info. The factory service manuals do have some circuit descriptions, But they seem to intentionally not spell it out very well. On the wiring diagrams, the OEM books will be better, but you'll need to go over all the years and models for the different bikes you'r working with. This is one of those spots where the right tools (info)will really be important. Good luck, Bob. <p></p><i></i>

I have the complete OEM Yamaha wiring diagram for the 1990 FZR1000. I will verify its whereabouts and photoshop whatever is required. Not sure if this will help. <p>-John</p><i>Edited by: <A HREF=http://p072.ezboard.com/bexupbrotherhoo ... >jjs777</A>  <IMG HEIGHT=10 WIDTH=10 SRC="http://home.comcast.net/~john.stempien/ ... larger.gif" BORDER=0> at: 7/14/04 4:47 pm<br></i>

If not then the ignition black box & the black box relay unit that feeds the Ignition black box would be a great help. I have contacted Yamaha and the original suppliers of these units and all where unable to help.<br><br>When I solve the problem with all your help I will post the results for all to benefit.<br><br>Wow my head hurts !<br><br> Cheers <p></p><i></i>
