There should be a few small wires off the selinoid. Check the wiring diagram, one will lead to the starter button and odds are another will go to ground through a saftey switch.

It shouldn't be hard to find out which one grounds and ground it directyl then jump power to the other wire.

BTW, selinoids can and do go bad...

Thanks, Geezer. It's a new solenoid and operates when hooked to a 9V battery. My "remote starter" is a 9V radio battery that I hook to the two small solenoid leads, so I know it works. With the key on, the two wires have a small current going to them, but it stops when the start button is pushed.

Hey LoHo,

The solenoid's wires should be only 1 with power to it, the other wire should go to the starter button which is a GROUND, it shouldn't have any power! In the later model XS's, there were 2 red/white wires, one that goes to the TCI, the other directly to the coils. The other small wire is blue/white which is the ground wire that gets grounded to frame when you push the starter button which completes the circuit and throws the solenoid switch which engages and sends the high power to the starter motor.

The safety switches incorporated in the XJ were numerous, clutch, sidestand, neutral. They all short the power FROM the TCI, so they it doesn't get power, no start.

You'll want to check ALL of the ground wires, engine to frame ground, and also the contacts inside the starter switch at the handlebar. You should be getting 12 volts to one of the small wires that go to your solenoid, the other should be ground! You may need to clean many of the other connectors on the bike!

As for posting here, naughty, naughty!!

However, it's proper place is in the OTHER BIKE DISCUSSION forum, and that's where it'll be moved to!

Damn! Busted by the teacher! Guess there's no recess in my future...

**LoHo** · 08-22-2006, 02:17 PM

Could you guys keep an eye out for a little relay, an Omron 12R, that is the starter cut out that seems to be faulty. I assume that it must be used on other bikes, so if you have a rusting partzer with an intact wiring harnes, check it out for me. It's worth ten bucks and I'll pay postage...;^}

Hey Loho,

That part is still available from Yamaha, it's OEM # is:
12R-81950-00-00

I found it on www.cycle-parts.com for around $53.00 but they only sell $100.00 or more at a time!

BikeBandit: Shows it as being superceded by this #
2: RELAY ASY.
(4H7-81950-01) [RELAY ASY.] 7477-001 $55.22

I also found it on a Net Search on this FRENCH website for parts, and says it also fits the Yamaha XTZ-660, they sell it for only 10 Euros...can't tell if this is NEW price, or if these are used??

xtz-660 and you'll find reference to OMRON 12R-01 Relay only 10 Euros!

Good news and bad news...I went to the local MC salvage place and found a 4H7, which supercedes the 12R, and they wanted...5 bucks. Plugged it in and the starter system worked great. Just for kicks I hacksawed the old relay apart, a seemingly solid unit, and it was half rusted inside (hmmm...no current when the button is pushed, but partial current otherwise...how about RUST as a resistance/conductor?!).

On the other hand, the front cylinder does not always spark. When it does not spark while cranking, it does a spark about three seconds after I release the starter button, which has resulted in some SPECTACULAR backfires when the exhaust valve stays open. 12 gauge quality...dogs barking throughout the neighborhood, neighbors coming outside to have a look.

I think the TCI is okay, because I've managed to get it to run before, although not well. I can't tell whether the rogh running was carb adjustment or no/weak spark to one cylinder. Should my next investigation be the coil, the TCI, or some other ignition component?

I love intermittant electrical problems, don't you? A puzzle within a riddle, wrapped in a question....

Non-XS Log entry #6

Both coils work when plugged into one of leads, and the wires are intact. The pick-ups in the Stator were intact and had continuity. The center of the TCI gets pretty warm when trying to start the bike, so I think there is some sort of resistence inside the sealed unit. Other sealed components had taken water, so the TCI might have as well.

I'll watch eBay for another unit and take the one I have apart to see if it is repairable. I'll keep a signal fire going in hopes that someone might rescue me from this remote outpost to which TC has banished me. Food is gone, and water is running out...

Non-XS Log Entry #7

Starter problems are solved. Cleaning the TCI resulted in spark in both cylinders. I got it to start and it idles very smoothly! However, it only runs on full choke, so I must have further carb adjustments to do. Perhaps the floats are too low? And I still get a 12-gauge backfire every forth or fifth shutdown. That last spark, about three seconds after the starter stops, is a problem I have to solve before the police helicopter starts flying by again...

Log #7

I wonder if I could avoid that late spark by reducing the resitance in the plu and cap? The cap has 5k resistance...could that reduce the spark, but keep the coil charged until shut-down, then blow out the leftover charge when the system grounds, sending that late spark to ignite the the now out-of-time cylinder? I wish someone knew something about ignition on the Non-XS list....

Log entry #8

Day 29 on Non-XS Island...

...scored a replacement TCI unit on eBay. Spark seems stronger, but I still get the stray spark, although I haven't had the 12-gauge backfire lately. Rigging the horns has resulted in a fuse-popping dead short somewhere, but no big deal. I'm $200 bucks into a "free" bike that isn't reliably running yet, but the major problems are all solved. I'll go back to the carbs to try to solve the hard-starting/no throttle response problem. The petcocks are a one-off version with no shut-off or vacuum closer, but my needles are holding for now. The carbs are set pretty lean, resulting in full-choke starting and low rpms, even fully choked. Both tires are goners, but who buys new skins for a non-runner? Further success will just mean more expenditures. Aw well...what's money for, if not to keep old bikes running?

Getting tired of these damned coconuts...time to search for a better camp site and fresh water. Plus coconuts are natural laxatives, so this camp is getting pretty disgusting.

A lifeboat for ya!

Hey LoHo,

Geez, I can't believe nobody else has chimed in with any comments, guess that's an uncharted as well as deserted island!

I've reposted it here in hopes of more/better feeback for you!

I think you're on the right track with regards to the carbs, as with the XS11, they are the bain of our Xsistence at times!!

**oseaghdha** · 09-19-2006, 04:38 AM

If I was to reply about a non XS, I would recommend tearing the carbs off and giving them a good cleaning. The XV is very sensitive to float level, and a gold plated PITA to adjust. Use a small clear tube on the drain to check, should be at the split line +2MM - 0. You will need to drill out the idle caps to clean the idle circuit. I was able to R&R the carbs on mine in about 3 minutes before I got it right.
But, this is an XS page so.......... I got nuthin.

**mainlylinux** · 09-20-2006, 05:14 PM

I ended up replacing my solenoid with one off of a Ford car. I have the part number around somewhere...I think I paid 12 bucks for it at Autozone.
