why did you disconnect the starter solenoid its not in the reg cicuit

 

He probably went to a Lithium Ion Battery if he upgraded to a MOSFET and took everything in the charging system at that time

 

The positive battery wire goes to one side of the solenoid the other to the starter

The starter is tripped by the button
The neutral switch or clutch switch provide ground for the

Solenoid trigger winding so again what does that have to do

With the charging system or am I missing something

 

I havent removed anything yet just covering my bases so the superkit from roadstercycle has a red and black that go to the battery and i also have a lead to the solenoid do I attach both to the positive terminal of my lithium battery? My gut says yes

 

This is for my Transistorized ignition M-unit set up - not same as yours, except for the area you are referring to.
But it will give you an indication of what goes where in that region.
It's a good idea to download the factory manual and look at the wiring diagram that applies to your bike. Start getting familiar with looking at these diagrams....use a coloured pencil to trace lines you are interested in.
Good luck.

 

Doesn't the black RR sense wire go to the positive side? Or should that wire be green? .... Or the makers of the RR have colour coded ground as black?

 

Yep. They coded black as ground.

 

I suspected I was misunderstanding. So ... there IS no sense wire?

 

Not as far as instructions from supplier go. What does the OEM black sensor wire actually do...make system live when ignition switched on?

 

The red wire in the standard RR pumps the power into the battery. The black sense wire is used by the RR to sense the state of charge and tells the RR when to start dumping excess power.

If the new system doesn't have one I guess it senses through its red wire.

 

Ok so red from RR to solenoid and then black to wire and regular red to solenoid is still on positive battery terminal correct?

 

Red to battery side of solenoid. Black to good solid ground - negative battery terminal is good.

 

Next question what do you do with the other wires that went into old rr the red, green, and black ones with the red clip

 

Wait for further advice, but my guess would be that they are now redundant and can be clipped out.

 

@swanktango - I just got my mosfet and am going through the exact same confusion. Did you ever get this resolved?

I’m going to try sketching up some diagrams later and searching the web deeper for help - but the main confusion I’m seeing right now is:

1) everything I’m seeing so far about the MOSFET says to wire it directly to the battery (but right now I’m assuming this is incorrect and it should be wired into the white/red wire from the solenoid/starter relay)
1) EDITED ANSWERED - just wire it directly to the battery (pos & neg) just to minimize resistance points, via https://cx500forum.com/forum/technical-help-forum/34912-wiring-shindengen-mosfet-fh020aa.html
and have the starter relay also going directly to the battery

2) if it’s getting wired from the starter relay does that mean to add the included 30 amp fuse here (in the white/red wire) and keep the existing 20 amp fuse too (which is in the red wire going to the ignition switch)
2) EDITED - having the MOSFET going directly to the battery I'm assuming I should add the 30 amp fuse as directly by the MOSFET diagrams, while also keeping the Main 20 amp fuse where it is correct?

3) THE MAIN CONFUSION - the existing regulator has a “power out” wire (black) and the MOSFET does not, where this get tapped into from?
3) EDITED - after reading CXPHREAK about this black wire being a "Sense wire" that would just completely confuse me - because following this black wire throughout the original cx wiring diagram it must be a power out wire.. right?
3) EDITED AGAIN.. after doing some digging found that the black wire coming from the OEM RR on the 78-81 CX500 serves a different function then on the 82 + CX500 and on the 81 + GLs.. This could be part of the confusion in regards to the black wire being a "Sense Wire". My bike is a 79 cx500 and the black wire from the OEM RR is going to the Rear brake light switch / Horn / Turn Signal Relay.. etc.. so I need to figure out how to safely feed this power.
3) EDITED AGAIN AGAIN... So after looking at the wiring diagram more it appears the "power out" wire (black) I was referring to gets connected to power when the Key is turn On - which would in fact make sense that this is a sensing wire, and that the RR isn't sending the power to my "Rear brake light switch / Horn / Turn Signal Relay.. etc.." its sensing the power at the end of the circuit. Is this correct?
EDITED ps My apologies for ever doubting you CXPHREAK XD - and for not better understanding how a RR works - still learning

My apologies if this has been answered already - I’ll be doing more digging and if I find a clear solution update my wiring diagram and post it.

 

Dude no I haven’t figured it out yet ha I’m looking at it still let me know what you find

 

I think I have it good understanding of it all now - I haven't wired mine up yet because that's still a few steps away for me. But after looking into it all this is my plan of action (see screenshot).

Side note - it does sound like the 30 amp fuse isn't required - but is recommended.
