Stator coil wires??

Ok so I am trying to test my stator. Well the manual says to track down the 3 white wires and use the ohm tester. well I can't do this yet because I have to go buy some allen head sockets tomorrow to get my side cover off to trace the wires but I was wondering if anyone could get a picture maybe off of a manual and point out where they are at to maybe save me some time. By the way I have a 92 xj600s.

 

If you go to www.carlsalter.com you can download a free pdf version of the diversion/seca II manual.

You do not need to undo the stator. Find the voltage regulator and unplug it. It is underneath the l/h or r/h side panel (I think). Ther are either 4 or 5 wires. Red charges the battery and there may or may not be a black (On later models). Left pic is an early 4 wire model and the right the later 5 wire.


Just test at the plug - no need to dismantle!

One word - well a few - of caution. Be aware the diversion (And my bike because it is a later model) use a permanent magnet alternator. So if anyone says "Check your brushes" - it does not have any!

 

ok yea i found that plug pretty easy earlier but i wasnt sure if thats where i had to test it. and it has 3 white and one red wire. So I have a multimeter that has the ohms selection on it.. will that work?

 

That's the guy. Check each pair of white wires. I think the spec is 0.5 ohm. Don't be surprised (or concerned) if it reads a bit higher (1-1.5 ohm). What you're really looking for is that it's not open or shorted.

You should also check each white lead to ground. They should all be open, or infinite resistance.

 

in the manual it says it should read between .32 and .48

 

0.5 IS 0.48! Don't forget you are also measuring the resistance of the meter leads and is your meter that accurate? What were your symptoms- Fried battery , Flat battery, lights getting dimmer?

 

my sypmtoms were I bought a new battery. charged it.. let idle for like 30 mins. Went to go for a ride after idling and it died within 5 miles from the start. Had to jump it 5 times to get it home that day. Have since tried it all over again and same thing keeps happening. Didnt start doing this til after I put the new battery in my bike. Took my battery in to be tested but since I didnt have it fully charged they couldnt tell if it was bad or not.

 

I would charge the battery then start the bike. Use your meter to test the battery voltage (I think there is a testing section in the manual). At Idle, the alternator output will be low so only expect 12 or so volts. Over 2000 rev/min, the alternator should start charging the battery, so expect 13.5 to 14v. If you rev further the output shouldn't go above about 15 volts. The exact figures are in the Haynes book.

A rough-and-ready check is to run the bike and switch the headlight on. As you rev the engine, the lights should get brighter.

If the stator checks out ok, make sure there is continuity between the red wire and the battery positive, before you condem the regulator.
This was a fault i had years ago on an old Honda 500, where a connector was corroded.

 

The alternator doesn't produce charging voltage until about 2,000RPM. It's a wonder it didn't die before you started to ride. I can envision you riding off on an almost dead battery and before it gets a chance to take a charge you use the brakes, lighting the brake light, and killing the ignition due to low voltage. There isn't enough juice in the battery to start it so you jump it. It runs until next time you use the brakes. Repeat all the way home.

Charge it up again. Start, measure battery voltage at 2000RPM. If you've got more than 14V your stator, rotor, brushes and rectifier circuits are all good. Run it up to 3000RPM, if the voltage is below 15 the regulator circuit is working too.

 

Here's a real quick check: If your headlight doesn't brighten up a bit when you rev the engine off idle, then you know your battery is not charging.

 

ok so i tested the stator and it seems good. my battery is fully charged. when i bought the battery i put it on directly from auto zone where i bought it. Didn't do any charging to it before I tried riding home an hour on it and thats when i had to jump it 5 times. Could riding on it brand new without charging it have ruined my battery in someway to where it wont keep charge?? any help is greatly appreciated.

 

I would have thought that if the bike started, as long as you were running at reasonable revs, it should have charged.

I think the battery should be ok.

What results did you get measuring the battery voltage at different rpms?

 

well the meter I have isnt the best and it just read into the good and not the replace part.

 

Ok, Perhaps you know some one who has a voltmeter/multimeter who can help, or test it for you.

It's really important to know what is coming out of the regulator to advise you better.

One quick test - unplug the regulator and put a meter between the red wire in the plug and the black wire to the frame of the bike. You should be measuring the battery voltage (Dont run the engine). If you cannot "See" the battery voltage, there is a wiring fault between the regulator and the battery.

Regulators can fail but who wants to spend $80 unless you have to!

 

i have a multimeter and when I tested the regulater plug it made the needle go all the way to the right whether I had it on 10 all the way up to 1x

 

This might sound a daft question, but can you pm me a link to the type of meter you are using. It sounds like it isn't on the right range. I might be able to advise you better. Alternatively, if it is a basic auto/battery tester which just says bad or good it won't give the information we need.

 

would either of these meters work? I went to my local bike shop and explained to them what was happening and the mechanic said it doesn't sound like the stator but it could possibly be the voltage regulater. But will either if these meters work to test it??

Yes - as was said before, you need to measure 12 - 15 volts dc accurately. Also 0- 5 ohms for the stator winding resistances.

As far as I know, you cannot test your regulator (But you could the earlier ones). so it is a process of eleimination. If the stator checks out and the interconnecting wiring to the battery is OK then it will be the regulator

well crap. I'm not very good with electrical stuff lol. Maybe I should spend the $30 bucks to take my bike to the shop and have them do the testing for me

 

That might be a good idea, especially as they seem to know what they are talking about.

I work as an electrician so am happy with these sorts of faults, however I find the pure mechanical stuff harder!

How about this? $14 for a regulator - if it isnt the fault, you've lost almost nothing!
