HELP 1982 xj650j project PLease helpxj650j & xj650RJ wiring?

Hey guys iam new to this site its really cool.Iam 15 and i have been building my 1982 yamaha xj650j maxim from the ground up completly by myself. for these last few weeks Bought as frame and box of ok parts. i should be getting my last parts in soon and then iam done..15 and already built my first bike haha so its a wiring harness that im getting, i found out the one i ordered goes to a 1982 xj650RJ and i have a 1982 XJ650J ? it should be the same and fit right? please say yes please say yes...!!??

thank you- : tyler

 

yes, well kind of yes i scanned both diagrams and laid one over the other with photoshop and they seem to be the same but i didn't look at each wire
no big difference though

 

I think you're going to run into issues with the following areas:

- gauge cluster wiring esp. tach wiring
- rear tailight wiring
- Seca models have two horns, Maxim only one, no biggie but just be aware

 

Welcome Tyler! 15 and chomping at the bit, I like him already.
Well fellas (no disrespect to our lady folk), think we can learn the boy how to read a schematic??? Tyler, do you have access to any electrical tools such as a volt/ohm meter? How about a soldering iron? Along with basic knowledge comes the need for tools. If you have the tools, then you are half way there. We have had a couple of members put together tutorials on basic electricity for bike owners. I will confess I'm to lazy right now to pull them up for you so consider this a homework assignment. The adaptation of the RJ harness to the J configuration should be an easy swap. Extra wires are ok, just need to terminate them properly to prevent inadvertant shorts.
Tyler, let us know what you are familiar with and we'll start from there. Make sure you get yourself a manual (Chacal, our parts guru, has the Haynes manual cheap) and read up on both the RJ and J model schmatics. Post a general location for yourself, you never know if help is around the corner.
Best of luck to you!

 

AWESOME TYLER!

did u remember to wire up the ignition key ! jus kiddin

Welcome Tyler, was this a rolling frame when you got it? if not & you don't have a manual, I would be slightly worried about the safety angle, the way the wheel bearings, brakes, head bearings, forks, go together, all have a significant safety aspect & we don't want anything to go pear shaped. Have you got anyone who can check your work? Your age is not a problem, I built my first bike at age 9, but it wasn't an XJ by several quantum leaps.
The guys on this site have all the answers, if in doubt ask.
Good luck. Wiz.

 

I know electrical and ive been building this without a manual i know alot more then people would think. the old wirirng was crap completly fried evrywhere it was cheaper for me to buy a good used one then fix that one. I have alot of electrical tools and i have brakes i bled them they are fin obviusly ill go threw it to make sure it is safe im trying to fin out if this will fit.

 

Ok, a background in electrical means you have wired houses? What is your experience background? Please expand on this. It is important to know not only how to look at a schematic but how to understand it. And please don't worry about the questions, I need to know if you are indeed ready to take on the dragon! We want your efforts to pay off the first time! No manual? You got guts but I'll agree with Wizard, there are some aspects to the wrenching of machinery that must be done by-the-book in the interest of you and other's safety. Brakes being high on the list. I'll ask, are you using DOT 3 or 4 brake fluid? Does the brake lever fully engage with the 13mm gap between the brake lever and the handlebar grip at full compression? What torque do you have the banjo fitting set at? All of these questions are meant to stimulate thoughts of what you should be concerned with. No offense meant.
Let us know what shape you are in.

 

I have wired dirtbikes snowmobiles. I understand shorting i understand testing i under stand mulitemeters i can talk to someone 30 years older than me and understand what they are saying i understand current computers fiches i can splice but what im confused with is could i run my bike with the 1982 xj650rj harness and just not use the stuff i dont need?or simply cut it off. the compression on the front brake lever will almost go all the way down but wont. it does need brake pads anyway i was just getting come brakes for now anyway for testing.If i have someone to talk to as i go threw this process of putting this harness in safly and correctly i will be fine. As far as i know im in pretty good shape but this wiring really gets crazy sometimes as we all know.ther harness should be in today or tommmorow

 

Thanks Tyler. I'm in school the next few days but I will try to answer your harness swap questions by the weekend.
Typically cutting off parts is not desireable. Tuck the odd ends away until the machine has been operated for a while and works right. Once that occurs, I'd clean up only if there are issues with fitment of other components.
Brake pads are a wise investment, can't go wrong there.

 

Yeah i really do think that this harness WILL work .. ive looked over the diagrams sooo many times ive counted everything ive checked evrything and witht the given information between the fiches it seems to look like it would work.The only things i see that are different are the horn and the ignition modules are not the same part number one has a g on it and the other doesnt and the 2 relays are not in the same spot. i have faith ill try my hardest and if i cant then ill buy another and then ill have about 5 of them haha. thanks for your help
