Running Without Stator Output

Hey guys,

Bike died when cooling fan came on as I pulled into work this morning. Unfortunately, I think it's the stator. If I charge up the battery before heading home, how long do you think the engine will run? I am thinking 20-30 miles or 45 minutes, which would be enough to get home.

too many variables to be sure, but I'd guess no more than 30min of run time....probably less.....

Can you get access to a volt-meter?

If she is pushing some charging (13v+) at 3k+ rpm then you should set your idle abnormally high (2k). I've gone around 20-25 minutes without any real stator output, but I had to keep the revs going at stops.

Could always strap a car battery in the passenger seat and tie that in as well (parallel, not series!) that will get you home. Push start the bike so you don't drain the battery trying to start it also.

Don't think there's any chrarging going on at all. Could be the R/R, too. I think I'll just call AAA and tow it home 20 miles. I have RV/Motorcycle coverage for 100 miles. This will be a lot safer than stalling while lane-splitting in Los Angeles during rush hour.

Sorry for the bad luck today If you need any help when you're doing your stator let me know.

My Vulcan rode home on a flatbed. Stator voltages are 50, 50, 45. At this point, it looks like at least my R/R is bad. What do you guys think about the 10% variance in voltage? I suppose that once the stator is loaded, things may change.

My bike ran only about ten minutes with a totally dead stator and a manually charged battery. Disconnect the headlight, that should get you longer.

My stator died on me last year, and I found out the hard way about 90 miles from my house. I disconnected the headlight and tail light fuses and jumped it, and made it about 50 miles until I ran out of gas......

im more concerned with the low numbers.. normally we hear reported 60-80 VAC... not 40-50 VAC. check the 45 for short to ground. fallow my Charging System Flow chart.. it will pinpoint exactly where your problem is.
