wiring chop up!

i just bought this 81 550, and i decided to redo the wiring witch was hacked but i guess i didnt know it was this bad, i have spent some time on it and haven got anywhere. the last owner really hacked it up there is sh!t spliced everywhere. i have wiring diagrams off this site but im not to savy with the wires. all i want is the bare minimum for the bike to run, headlight, tail light, blinkers and a simple on-off switch. is there anyone that can help. also there are a few items i cant figure out what they do or where they came from.


I dont know what these are.

The bike after the bob almost there

 

What a bird nest! Find the PO and slap him. :lol: Sorry can't help with the wiring but I'm liking the bars and the sissy bar. :twisted:

 

thanks man , i think i just solved my problem i bought a full harness of ebay i will keep everyone posted on the bike!

 

Half the stuff is missing that the stock wires went to. You need to find someone with a similar bike and see what you can do from there.

You probly didn't need to buy a complete wiring harness, everything on my bike is new (old recycled) wires except the regulator, starter and coils, I just found out what the bike needed to run and kept that and threw the rest in a box to be stripped and color coded for the next project.

 

BTW that is a 650 or 750 not 550, the 550 is chain driven, check for displacement inbetween the exhaust header towards the top it will say.

 

i was told it was a 550, but now that you say that i did notice that the drive was different. Will that make a differecnt for the harness i bought?

 

I dont see it working... wiring on each model is slightly differrent.

 

damn im back to square one

 

Weelllllll I wouldn't go back to square one the main things you need are the plugs from/to rectifier regulator, pick up coils, tci, and that kinda stuff. I am ready to help you wire that bad boy, cuz I have done it myself, and I am on here everyday pretty much, it isn't rocket science. You just have to remain calm when faced with a can of colorful spaghetti staring at you.

 

At least you have different colored wires, it could be worse. :roll:

 

Thanks alot man, i am just doin little thing for now. untill i have the time to dive back into it i will def. let you know thought. is there any thing i should start with first?

 

There is a post somewhere on the forums for a completely minimum wiring setup with schmatic. You might try to find it. I'd be interested in your leftovers (the connectors mainly).

 

Where does the key factor in on that diagram? do I need more than just the red/white lines from the key?

 

The key in that diagram is labeled on off, basically you feed hot from the battery through a fuse to the rect. reg. then to the on side of the key. Rect reg is hot always. The key is shown turned to the park position on this diagram. Wich is something I didn't use on mine.

 

no wiring updates yet but i went hard tail! looks alot better that stock frame

 

Nice job, but you might want to put a strut on the the bottom along the shaft to the drive pumkin for extra strength.

 

diggin the bike man pretty interested to see how it goes yamaha revoloution

 

Nice, Wish I had the ability to make my frame look that nice. My welder is a cheap pos. I could have used a buddies but I wanted to do mine all my self... Anyway.. I am working on my wiring at the moment also. I think I have figuered mine out. It isn't to hard, you will ENJOY this thing when it is done. Looks 100x cooler than mine!

 

yeah man, that frame turned out pretty sick looking. I also am digging the sporty tank, and the 70's style twisted bars. great looking so far!!!!!

 

thanks guys ill give you a little run down of the finished product, so far im not sure on frame color wrinkle finish black or brown, but the tank and fender are getting metal finished(bare metal and clearcoated) i have a buddy who is a CNC machinist so i have brass that i am making spike bolts for some motor/accessory parts. also making brass grips. highway pegs that are brass knuckels and i am recovering the seat with flannel and brass tacks to hold the material and i am making a fork bag to match the seat.

 

this is how I wanted to do my frame, coming straight down the back, but I couldnt figure out what to do with the battery, i couldnt get enough clearence? How are you going to make that work?

 

the batterys no problem its a little snug where i put it but i like it, you can also weld it to the swingarm

 

very nice man. thanks for the pics as well. helped me to visualize much better

 

finally got my fender in so i went to work on that today got it all mounted up along with the seat.

 

What did that truing stand ever do to deserve that? Clever use of the arms for the fender brackets... Wish I could just start hacking something like you creative guys. Don't have a creative bone in my body it seems (that or I'm yellow).

 

haha what the hell is a truing stand... i made the struts

 

Nice job man! Diggin the stance, the bars, the tank.

 

I've got a bicycle/small motorcycle wheel truing stand that has uprights with the same dogleg and slots on it. Did you get those out of a BBQ? They look perfect for skewers...

 

I dig those duct tape pods! :lol: But seriously, what are you going to use?

 

i have uni airfilters. i just took them off so i didnt burn them when i was welding

 

started the wiring today, i think im on the right track but i am having a problem with the pickup coil i am not getting spark. also i have a main switch and a button starter when i push the button the soilenoid just clicks. im trying to copy the minimum wiring diagram

 

when i jump the solenoid it will crank, also im not getting spark AWW.
