Aggrevating switches bypass

Will grounding the r/blk wire to the CDI accomplish this? Trying to do them all at once.

Jim

Does the cathodes of all three of the diodes in the diode pack have to be grounded to run the starter motor?

?????

As you can tell, I'm still trying to make sense of the A9 wiring diagram. Is it applicable to my '98? Where is the starter lockout switch physically? Guess I will give up and bypass the safety switches individually? Rode to town again this morning and my old knees needed help with the bump start....Does there exist a schematic diagram, or are we just stuck with wiring diagrams?

Grounding the input side of the diode matrix would be a Bad Thing, as you'd be bypassing the diode function which is to prevent current backflow from the 'safety circuits', one to another.

As far as I know, there's only the wiring diagram.

I believe that the starter lockout switch is the clutch switch.

Thanks, Tom - I will study some more and NOT do anything until I KNOW what I'm doing(however, that will probably prompt more ?'s).

Jim

I tried to make sense of the start switch diagram on the A9 diagram -but- can,t tell which wires go to the solenoid(coil) and which to the contacts. I can guess and feel pretty sure I figured it out - but schematics make things so much simpler.... One of the guys re-drew the engineering diagrams for the Honda Valkyrie - what a job that must have been!

See- I'm not the only one that has to make assumptions to make sense of that diagram? I haven't even been able to blow the horn - without guessing!

I need steering again-Aren't the input(cathode sides grounded anyway - thru the safety switches? My head is starting to hurt!

Jim Sizemore, this file may provide a wiring diagram closer to a schematic than what you're looking at now (Chapter 17):

http://www.diagramasde.com/diagramas...03+clymer).pdf

This is the whole Clymer manual for Generation 1s; I saw no copyright protection warnings; AFAIK this is public domain.

Anyhow, the RED/BLACK wire from the CDI must "see" a ground for the bike to run; the ground can come from several paths.

The starting circuit relay can pick up a ground from either the starter lockout ("clutch safety") switch or the neutral swith.

Switching logic prevents engine operation with the bike in gear, clutch lever out, and sidestand down.

As to the starter relay connections, the great big one connects directly to the battery positive terminal; the small connection connects to the starter circuit relay. + 12 VDC on the latter (from the starter button) engages the starter relay, connecting its contacts and powering the starter motor.

Wasn't gonna do this, but . . . here's a matrix of safety switch scenarios, a partial chart (the "how it works" column is missing), from an Internet posting long ago and far away:



Wish I had done a better job of saving the info, but--maybe this will be of some use.

Clymer manual

This is taking the guessing out for me. Wish my local had a place that stocked a manual. Thanks to you folks, things are starting to work out. Appreciate your patience with me. maybe we have helped others....
