81-83 xv750 diagram (SOLVED)

IGNITION

going at a different approach for a bare bones diagram. this is just a follow along. no commits needed.....
this is a factory diagram..

81_83_us_XV750 wiring good.jpg

this is the same diagram that i made blank and left the loads there..

81_83_us_XV750 blank.JPG

when i get time. i am going to do a section at a time. i will start with the ignition and r/r first.
everybody wants bare bones but all want different things.. such as no tach with all the lights. or no lights and no tach. tach and lights. no kill switch. kill switch,no lights and with tach. etc, ect, etc.. what i am going to do is do every combo that i can think of. there should be no questions when this thread is done. if this one works out. then i will do other models and sizes.

added the battery 12 gauge wires.
positive i have start at the 20 amp fuse. from the fuse to the ignition switch and r/r.
negative i start from the battery negative connector to the r/r.

now the ignition switch has battery power along with the r/r.

81_83_us_XV750 battery.jpg

now the fuses are connected from the ignition switch.
blue and brown from the switch is hot when the key is turned on. these 2 wires feed the fuses making the brown, red/white, blue, red/yellow hot when the key is on..
the brown has a factory splice between the ignition switch and fuse box connector. this connection is for the r/r.....

we now have 4 wires at the fuse box ready to be used.
blue, red/white, brown, red/yellow. the red/yellow feeds the headlight. this will not be used any more. this leaves a wire to use for a ipod or phone.

81_83_us_XV750 ignition fuses.jpg

this is the red/white power supply from the ignition fuse to the kill switch to both coils to the TCI finally to the starter solenoid.

81_83_us_XV750 ignition power.jpg

this is the same but no kill switch.
so the red/white starts at the fuse marked ignition then to both coils then the TCI finally to the starter solenoid.

81_83_us_XV750 no kill switch.jpg

ran a ground for the TCI
ran the orange and gray wires from the TCI to each coil. ran the blue/white wire to the solenoid.. the ignition system is done.
this diagram is with the kill switch. if not using the kill switch nothing changes just bypass the kill switch like i showed in the diagram.............dan

LIGHTS/LOADS

decided to use the blank diagram.
i am first starting with the brown power wire from the fuse box.
starts at the fuse to the horns. if not using horns then do not run the brown wire to them. then to the neutral light. if not using a neutral light just do not hook it up. same as the tach. if no tach then do not run the brown wire to it.
this brown wire also feeds the 2 brake switches and the turn signal FLASHER (not a relay like in the diagram) the flasher is a 2 prong car flasher. if you do not want signals then do not run the brown to the flasher.

81_83_us_XV750 brown power wire.jpg

added the brake switch signal wires to the rear light and a ground we now have a brake light..

81_83_us_XV750 brake lights.jpg

ran the brown/white from the flasher to the turn signal switch. if not using turn signals then do not worry about this wire......dan

81_83_us_XV750 flasher signal wire.jpg

[totallyredvirago]

signal light wires are run. if not using indicators in the cluster then do not run the wires to them..

81_83_us_XV750 signal lights.jpg

next i added a toggle switch for the headlight. parking light, meter lights and headlight will not come on until the toggle is flipped on...

81_83_us_XV750 headlight.jpg

the grounds and horns hooked up.

81_83_us_XV750 ground.jpg

and last the neutral switch wire.

81_83_us_XV750 neutral wire.jpg

added the tach with the lights due to the brown wire that feeds it is also the wire that feeds the brake switches, neutral, horns and flasher. also the ground is part of the headlight ground. again if no tach then do not run the brown and the orange wires...........dan

81_83_us_XV750 tach.jpg

[totallyredvirago]

added wire gauge...........dan

Damn this is a good write up. I'm not quite ready yet to be hitting the electrics, but i reckon in a couple of months time - this will be an invaluable resource. Thanks TRV.

So if I do bare bone my bike and I remove the relays, switch ect. is there anything else not on the diagram I can or need to remove

[totallyredvirago]

dont know what more you can get rid of.
after all you are losing 9 connectors and 34 wires just for the ignition side of the harness..........dan

[Viragoboy]

haha yea I'm not complaining! I just wanted to make sure there was nothing else I had to remove. And would you just recommend pulling off the whole harness and digging into it that way or would that just lead me to complications?

[madhatter4119]

Since you are doing a bare bone...it would be really hard to do with the harness still on the bike...Are you using your stock connections with new wires or
your stock wires with stock connections...if any stock wire aren't nice and bright when you go to splice them together...replace it...keep a eye on the ground
wires...Good Luck

[totallyredvirago]

if you run the blue/black to the dimmer switch the headlight will be on as soon as you turn the key on and while cranking on the starter. this is hard on the battery and starter. this is why i installed a toggle switch. the toggle switch will not allow power into the dimmer switch until you select the toggle to do so........
another way around this.. and this is what i have. a 2 turn ignition switch. turn the key 1 time and the ignition is hot. once the engine is running. turn the switch again and all the loads are powered up (lights).........dan

[goodpw]

Ah yes...good point about the starting. I will probably try & find a 2pos ignition.
Cheers for the help.

[goodpw]

Just had a thought.
If i'm changing the ignition I wonder if it's worth going for an auto motive type with a sprung ignition/starter & do away with the handlebar button ?
Might be a pita if I stall it at the lights or such like, but would mean I can use a trick throttle assy.
Goody.

[totallyredvirago]

yes i have wired in car ignition switches.
just run the blue/white wire going to the solenoid to ground. run the red/white to the solenoid to the center ignition post. when you turn the key to the crank position. the switch will send 12v to the already grounded solenoid. this will engage the starter only..........dan

[xtremehunter83]

bump for bookmark for when i work on wiring to barebones

[totallyredvirago]

dont worry about bumping it up. if it gets lost just pm me and i can send it to you..........dan

[xtremehunter83]

cool, i read somewhere if you make a list of what you want you may have a diagram already made? is that true? i wanting just what needs to run plus one horn, headlight, tailight, and turnsignals..... the less wires and relays the better lol


also i havent read into it much but seen mention groundng... these bikes have grounding issues?

[totallyredvirago]

yes major grounding problems.
factory has everything tied into the r/r 12 gauge ground wire to the battery cable.
i have just the r/r grounded to the battery cable. the headlight, TCI, horns, tach and signals go to there own ground.

if you want different things to use. make a thread and i will help you. to load this thread with what you want will probably take it over 100 posts.......
sky is the limit to mods that can be done. nice thing about the 1st gen. no relays at all needed. but you will have to get a toggle switch or a 2 turn ignition. for the headlight. also a 2 prong car flasher for the signals to work...........dan

[xtremehunter83]

cool, ill make a thread and go from there, thank you very much for the help!!

[xtremehunter83]

i had trouble at work getting links to pop up.... where does the white with green trace wire from the r/r go to??

and which diagram had the push button start wired in?

[totallyredvirago]

white/green does not get used. it goes to the diode. the diode is no longer being used so no need for the white/green..

the blue/white was added in the last pic under IGNITION.
if you go to the LIGHTS AND LOADS you went to far........dan
