I attached a pic from the service manual. The terminals are all on the R/R itself.

vn750joe Thanks for the tips everyone.

Last night I pulled out the battery, cleaned the connections. There was deffinately some corrosion going on inside the battery box but it appeared that it's been there a long time. Maybe from a previous battery? I didnt see any wiring below the battery box....... but I admit I didnt go on an extreme hunt for wires.

I'll get on to new battery and R/R testing soon as can. As well as stator location.

Need tires, brake bads, fluid change and probably a tune up. I'd really like to get the valves checked too. Need new hand levers, grips, mirriors and lots of TLC.

Oh and I DID concider the possibilty of perhaps a slight idle adjustment? Thanks to dsr for reminding me.

I am hoping that this doesnt become a lesson in frustration but I am perfectly ok with this being a fixer upper/ cleanup project.

BSkaggs513 Great post and description!

I am inexperienced at the R/R so I have a couple of questions for my clarification. In your post, is the G,M,B terminals on the R/R itself? And, is A1, A2 and A3 in the plug connector?

Lastly, should I run this check on my bike if I currently don't appear to have any charging issues? (I know I will now that I made that comment )

Thanks again!

hyperbuzzin Here's the R/R testing instructions from the Vulcan Verses......

If you have the Kawasaki Service Manual, you will find R/R checkout on page 15-18. If you don't I will list what is there for you. Quoted from the manual as much as possible: Regulator/Rectifier Inspection Remove the left side cover. Pull out the connector. Be sure to set the hand tester to the 100 ohm range and zero the meter(Not necessary on a digital meter) Check the resistance between the regulator/rectifier terminals as follows(there is a chart and picture in the manual which I cannot reproduce right now but I will try to put it in words for you)

A1 A2 A3 All Alternator Terminals --- --- --- Connector with pins facing you and notch at bottom --- --- ---

G M B, G = Ground M = Monitor B = Battery --|__|-- (Hope that came across right)

Measure B to M - should read infinity

Measure B to G - should read infinity

Measure B to A1, A2, A3 - should read infinity

Measure M to B - should read > 10K ohm Measure

M to G - should read > 10K ohm

Measure M to A1, A2, A3 - should read > 10K ohm

Measure G to B - should read between 0.4 to 2K ohm

Measure G to M - should read between 1 to 5K ohm

Measure G to A1, A2, A3 - should read 0.2 to 0.6K ohm(200 to 600 ohm)

Measure A1, A2, A3 to B - should read 0.2 to 0.6K ohm(200 to 600 ohm)

Measure A1, A2, A3 to M - should read infinity

Measure A1, A2, A3 to G - should read infinity

If there is more resistance than the specified value, the unit has an open lead and must be replaced. Much less than this resistance means the unit is shorted, and must be replaced. Hope this helps someone out there.

fergy I definitely wouldn't be riding it with this going on! Can someone give him the r/r testing instructions? I don't know the drill off hand. Hyper? Cindy?

i know what you got man

I had the exact same problem man.
Found out that my R/R was fried....My advice is to get a new one quick before it kills your strator.
By the way, the R/R form a Kawasaki ATV is the same as what goes on our VN750 ...plus it's $50 cheaper.

good luck.

PS: buy also a new battery , the one that you have is most likely dead cause of the R/R .
mine almost blew up

dsr Mine had the same problem. I turned the Idle up a very small amount and added 3 tbs of seafoam to my tank. It now starts while hot with only a touch of the starter. Wouldn't hurt to try some.

vn750joe Charging overnite seems to have no effect. As far a I can tell it just doesnt seem to want to run when it's hot. If I rev it a little it does keep it from dying. As long as I am in gear an moving it seems to keep chugging down the road.

Including today's July 4 joyride, I've acumulated about 100 miles of seat time.

vn750joe Thanks for the tips all. I really apreciate it. I will give the hands on sugestions a try as soon as I get a bit more time. I'm working late this week to make up for the holiday. (have to, not want to)

As funding becomes available I was hoping to make some of the other suggestions happen over time.

Here's a bit of additional info for thought.

I took it into town this morning before work to run some errands. Before I left I charged it on my truck via jumper cables for about 30 minutes. Went just up the road got it inspected. Shut down and restart. Went to the bank, shut down and restart. Went to the DMV to get my endorsement, shut down and restart twice. Brought it home and parked it for the rest of the day. Shut down and restart. Each time there were no problems. Again perception may be messing with over pure coincidences but it SEEMED to run better today too.

I got home from work too late to mess with anyhting. I picked up a Black and Decker "smart" charger from Wal-Mart and hooked that up. We'll see tomorrow if does any good. I plan to take it to work.

BSkaggs513 Fergy,
Thanks for the catch. I meant to say do buy the maintenance free battery. (I was quickly typing this post at work, hiding from the boss).
