So I went n bought a new battery 2 days ago. Was tired of holding my breath every time I went to start it up wondering if I was gonna hear that awful grind/clicking sound. Worked fine for 2 days fired up first try every time. Today I go to start it for work n what do I hear but that awful grinding. So I'm just guessing that SOMETHING is shorted or melted somewhere and this is more than likely the same short/melt that has blown 200$ worth of headlights. Any ideas were to start looking? | ||

Stator? | ||

How would I check that? Partner coming over with a multimeter in a few but I don't think he has much more of a clue than I do. | ||

It's pretty easy, first check the battery voltage, it should be 12-12.7volts DC. Next start the bike and rev it to about 2k, the voltage at the battery should be 13.5-14 volts DC. If you don't get anything over 12vdc with the engine running you will need to find where the leads from the stator plug into the regulator. On the tubers it is just above the oil pump and is a round connector with 2 pins. Unplug it, change the meter to AC volts, start the bike again and see if it runs around 27 volts AC @ 2,000 rpm. If not your stator is dead, if it does then your regulator is dead. There are more detailed tests but that is the simplest and fastest. If your bike isn't starting due to a weak battery, go ahead and charge it for awhile. | ||

Troll: find where the stator and regulator connect stator leads exit on the older engines top side just aft of the rear cylinder, from the primary case. un plug the stator jump start the bike, IIRC 36v or more AC, @ 2000 rpm this wiring connects to the regulator the stator should have no continuity to ground either wire, engine off using ohms settings next would be the regulator, IIRC front low (thats where its at on the tubers ) find the out put wiring you should see the voltage rise slightly when the engine is running and it should likely be in excess of 12.5 V dc ( usualy about 13 v ) If you have it refer to the FSM for testing procedures. you may also want to try the X1 files for relevant info ps check the battery terminal bolts first and the condition of the cables [ what IA mike said  ] (Message edited by oldog on May 10, 2006) | ||

Dog- I figured someone else was typing at the same time I was. Then when I reread mine before posting I changed it a little. I still beat you by 3 minutes! | ||

Nuttin worse then gettin beat like an ol dog  good advice Mike, | ||

Good advice, all. I went through those steps just recently and found only 1.42 volts at the stator connector. Sure enough... stator failure. The first thing you need to do is get the factory shop manual for your bike... that's why I knew exactly what to do when I realized I had a problem, and believe me, that's a great feeling. | ||

check for rubbed/ chafed voltage regulator lead where it contacts the front right corner of crankcase. . might be something REAL simple. | ||

If when your engine is hot you can smell tranny fluid, it's the stator. | ||

I didn't think about the smell test. I had a Harley's once that about knocked us over when we opened the inspection cover. That stator had to have been pretty hot to stink it up that bad. | ||

Still waiting on my buddy with the multimeter to do the stator and regulator tests. Could either of those being blown cause my headlights to blow? As it stands right now I get no power to one side of my headlights and the other side blows after a few rides. | ||

If your regulator isn't controlling the voltage to a max of 14vdc then that could be blowing bulbs. It quite possibly has cooked your battery too. Make sure that if it turns out to be the stator that you check your charging voltage several times. Some people have replaced their regulator after replacing the stator. When my stator died I just replaced it and haven't had a problem since. I bought a reg but it sits in the spare parts box right now. | ||

An intermittant stator short sure seems like it could be sending nasty spikes through the whole electrical system. A failed open voltage regulator SCR could be doing the same thing. That *could* blow light bulbs. My stator and Voltage Regulator inexplicibly failed within weeks of each other. I think the Mobil 1 gear oil killed my voltage regulator  | ||

Also, make sure your regulator has a decent ground. | ||

I think the Mobil 1 gear oil killed my voltage regulator you sure there reepi?  my chain case oil killed the bushes | ||

It melted the ice cream in my freezer as well. I'm sure of it.  | ||
