82 XJ11 wiring help needed!

[dbnawell]

Ok.. My name is Dan. Last Sunday,I found a 100 percent fully intact all original Yamaha XJ11 maxim with 3,400 original miles on it. The bike was layed down when it had 900 miles on it. It sat for about 4 years and then it was completely repaired and brought back to original condition which did not take much work as it was just layed down and,slid a short distance. The new owner that had it rebuilt rode it until it had 3,400 miles on it and then he died of a heart attack. His wife left the bike in the barn and 6 years later, which was last Sunday, I found it and bought it. I need as much information as I can get and I have already found a fair amount on the internet. At the moment my problem is wiring. The person that looked at it a few days before me had pulled some of the wiring connecters loose. I do not know why. Fuses are pulled loose, about 3 or 4 wires on the fuse panel and then I have a wire that looks like it is a sensor going to the battery but the battery is missing . Any info would certainly be appreciated.

Thanks a lot,
Dan

Hi Dan, welcome to the world of XSsessives. Check the Dutch Yamaha XS1100 Site out. They have a really good colour wiring diagram available. It is for the XS, but it should be a good place to start. The varioius connectors "should" only connect to to their respective mates. The rest of the connectors should all be colour coded. To save yourself the time going back and doing it later, clean the connectors, and apply some dielectric grease to seal out moisture before you put them together.

The fuse box is a common problem spot on these bikes. I would suggest a complete replacement of it. Doesn't have to original (you probably won't find one anyway) Several auto parts stores sell generic fuse blocks that will work fine.

As for the sensor, it screws into the battery. I think it's an electrolyte level sensor. Bike will run fine without it connected, yoiu will just get this annoying warning on the dash cluster. There is a way to cheat it so it will shut off. I don't have the link to it, but I am sure someone will provide it.

On the left of your screen, you should see a link to the Tech Tips Be sure to check this out as there is lots of tips for repairing common problems with the XS/XJ machines.

And finally, or maybe this should have been firstly, get a shop manual. Watch Ebay as they come across there frequently. Or, contact Rob Mills at rockjok@imt.net to get one on CD.

You need to read this tip as well What to look for in a neglected XS/XJ

Fuel system will be trashed, tires rotten, etc, etc......

I really thank you for being here to give me all this advice. It helps a lot. I want to be sure the engine is ok asap so I will know I am safe spending money on it.. I REALLY feel it is fine.
I will run straight to the wiring info on here tomorrow as I have been going over the bike all evening and need to catch some sleep. I still get nothing when
I turn the key on.Ony when I turn the key all the way over for
parking light does anything happen.
Can anyone tell me where to run a hot wire to bypass everything so
I can get a spark and start the engine? I have done all the normal stuff
like ALL connections I can find, the wires under the cover on left
side of engine (forget what to call them) and they are fine. The
wires and connectors on the coils look fine. I know where to hotwire
for running the starter and I am putting 12 volts on the fuse for
ingnition and get a small spark when I connect it but no fire to the
plugs..

Thank you, (and you and you and you)
Dan

I can't help much with wiring problems but I know this...I can't let my bike set with gas in it for more than 6 months without having to pull the carbs and clean out the varnish. If the inside of the tank has started to rust, your gonna have some rust that makes it to the inards of your carbs. Mine have been pretty gross more than once. And if the carbs have leaks, at least some of the gas ends up in the crankcase. I wouldn't rush to crank the engine if it's been sitting in a barn for 6 years. Have fun, sounds like a nice find.
