this charging system SUCKS

so its been a week of me working on this electrical problem. and before all you punks that are quick to ALWAYS say the stator....i checked it and its fine! she's only pumping mid 12s at 5000rpms. some connectors were bad.. I just replaced my bullets from the stator. I got rid of the pig tailed wires that were electrical taped. makes me want to find the last guy that worked on her and hit him with a lead pipe. pigtail wires? what was he thinking? none the less the system is still the same. the regulator checks out except for that white wire. ?? this kawasaki electrical system sucks. makes me just want to sell her and get a bike that's NOT a kaw..ever again. does ford own kawasaki? they do crap that makes no sense also. I was 2 seconds from kickin her over and posting her on craigs list. wated my whole day tracing wires testing and repairing wires. all to be right where I started this morning. if anyone can help please I like this bike too much to get rid of her and find something else.

Easy, Cowboy. What you're presenting with is obviously a charging problem - given the history of these bikes, folks were suggesting that you check the weakest links first - the regulator and the stator. Both of these are simple multimeter checks - .3 - .5 ohms on each of the three stator wires, and then you can check Clymer's for the measures across all the leads on the regulator. What was your resistance reading on the stator? And what are you getting when you check the regulator? You've only got three pieces to your charging system - the stator, regulator, and, ultimately, the battery. MF battery? Are you sure it's good? How long was it in there before you bought it off of PO? I've had batteries that charge up just fine on the tender, but don't hold a charge over the ride.

I totally understand your frustration with the bike, but as Jason and Grant on Ghost Hunters always say, "We're here to help."

The Vulcan shares this charging system with several Yamaha models so it's not just Kaw. Electrical problems are always a pain to deal with but deal with them you must or the bike won't run. In comparison to some of the Hondas I've worked on, this one is fairly straight forward.
Have you checked out Electrosport's troubleshooting page? It will list the steps to go through to check the entire charging system.
BTW, 12v at idle is a bit low but in spec. The question is, how much at 3k or so? I've missed something so I don't know what the white wire issue is. If it's like mine, it gets VERY HOT and melts the insulation. Chances are the R/R is way out of spec and will fail soon. Mine did. In measuring resistances, I found the stator to be partially shorted but functional. I opted to replace it as it will continue to get worse, not better and I'd really rather only replace the R/R once than have the stator take the new one with it when it fails.

So you call people punks and expect help?

What's that about.

Oh wait, you're just propagating the skateboarder stereotype.

That said, it's either your stator or r/r - you didn't post specs, and frankly someone who can't properly punctuate and capitalize might not have done all the tests needed.

Yup - I'm being a punk.

lmao

Actually, I think after 40 or so, one is too old to be a punk. That counts me out!

HA! This is funny...although I am not sure that chronological age is any determiner of how much of a "punk" you are. I have had the displeasure of encountering many people whom that title befit, who were way over 40...

Please do, some non-punkish 43 yr. old will buy it, think through it, troubleshoot it and repair it and have a great bike!

Sorry, but if you are getting only "mid 12's " at 5000 rpms...a short in the wires elsewhere on the bike is not the problem. If the wires from the stator to the R/R are fine, and the wires to the battery are fine...and you are measuring your voltage at the battery......Your R/R or Stator is the problem.

I went back and read your other posts, and you mentioned that battery acid dripped all over the R/R...not sure if this is your problem, but sounds like you might have good place to start. The wires/connections on the R/R could be bad, or your stator is not putting out enough juice.

See, even a punk like me is willing to help you out even if you do not want to hear someone tell you your stator or R/R might be bad.
