Charging isssues

So my 2007 R/W/B died on my on my way to work this evening. I was cruising along and looked down at my gages and they were all blank. No Tach, no temp, no fuel gage. Nothing. Shortly after that the bike stats bogging and then shuts down. Sounds like a lack of charging to me. So I did some poking around and it looks like I need to do The Drill (pasted below) and to check all my connections for signs of heat damage. Is there anything else I should do? I thought the electrical problems were fixed in the 2006 model year. Apparently not all of them. Oh, well. I'll get it fixed. I love the bike! I had purchased the VFRness just to be safe too bad I haven't installed it yet. Damn me!

Any advice or tips will be greatly appreciated.

The Drill

-Looks like you gotta do…. “The Drill.” ----ohwell.gif----
Go through all your connectors for burnt leads, dig deep. Crispy wires? Not good. The stator connector is the number one burn it up connector on the bike. - Your gonna have to fix that!

Then---Go through this starting point quick list. You will need a multimeter too.

Steps: ---
- Recharge battery overnite - then to take it to Autozone or similar to load test. -- Good? Bad? – An iffy battery can fake you out and act like a bad R/R. Buy new if needed.

- With good battery fire it up, warm up for a minute or two.

These are R/R quick checks---
--- With voltmeter at battery posts get voltages -- idle volts? 5000 rpm volts? What’s the numbers? Should be in 13ish min idle and in 14s at revs. (if in the 12s at idle, check at about 1900rpms instead. Its not unusual for the system to be in discharge at idle. )

- Check stator - These tests are done checking the connector that goes to the stator. (Engine off)
1. Pull connector apart. Set meter to resistance. Check pin to pin, 3 yellow wires, A to B, B to C, C to A. What’s the numbers? 3 separate readings --Should be less than 1.0 ohms.

- 2. Check continuity from each A,B,C pin to ground, -- -should be infinity - nada nothing. no continuity. -- 3 separate checks. (Connector still apart, engine off)

- 3. Crank it back up. Do another pin to pin thing, but set meter on AC volts. idle and 5000 rpms. What's da numbers? Should start 15 -20ish and climb 50ish and more. Again – 3 readings- (Again, connector apart) Repeat hot.

Edit

 

Thanks for the tip. I'll definitely get a hold of you if I get the FH020AA. I have the harness now. I might as well install it. :thumb:

 

Hi and welcome to the MadHouse:welcome:

When you get time please swing by the "Introductions" forum to say hi to the rest of the folks on here - don't forget to add a photo of your VFR.

You might want to update your forum profile (Forum Actions+Edit Profile) to include the specs of your bike and an approximate location - city/state is fine - that way they will appear beside all your posts automatically, and if you need help with an issue you might find someone is willing to drop by and offer advice - espcially if you have a well stocked beer fridge.

On a later spec 6th gen I would not waste my time fitting the VFRness - instead list it in the for sale section as it might be of interest to people with earlier gens! As you have seemingly discovered, crap components and the useless stator/RR connector are the main charging system issues with your bike.

Take care

once sorted, add a voltmeter

 

I'll make my way to the "Introductions" forum! I was wondering if anyone would notice that. :biggrin1: I updated my profile and added location and specs! Maybe I will sell the VFRNess. Not sure yet though.

 

Well, I already found one problem. See pics. That took about 15 seconds. Plus, it looks like the battery may be dead. My charger is giving me an error message.

 

I did get my battery to charge. I think my charger was just being stupid. Full charge of a little over 12.9V. Autozone says it's good so one step down. I took closer look at my fuse and it definitely has some heat damage so I'm going to swap it out before I do the Drill tests.

 

Whoa, that don't look right. It's been warm more than a couple times, Reason is why? Yea, Mello has this topic covered quite well.

 

Yeah, I'm not sure why. It seems that according the PO throwing electrical tape at it fixes melted wires.

 

Well, I got the wiring harness put back together with the new fuse holder. Now to do the Drill tests. Well tomorrow after I get off work and sleep anyway.

 

I got to the 3P connector today! I don't see why it won't charge. :hss:

 

Naaaaaaazzzzzdeeee

 

Nothing we haven't seen a million times before

 

Hey Mello Dude! How much do those brackets for the R/R run? I'm thinking about changing out the R/R whether it tests out good or not. Though I don't hold out much hope for it being good. I tried to PM you but you inbox is full!

 

So I was able to test the stator this morning. Does the phase to phase resistance jump up that much when warm? I checked them first thing then again at the end once it warm. Seems like a pretty big jump to me.

 

Typically anything over 1 ohm is bad news ... 1.5 ohm is kind of the max.

The stator may just be starting to fail ... THAT SAID ... what's most important is that your numbers are all very similar for them which they are.

Ok, I'll see about getting a new one then.

 

Looks like the previous owner bodged the wiring ??? Amirite? I assume the factory harness is all taped up and neat looking. (Haven't looked at mine yet)

 

Thats weird that the stator AC voltage output looks great, but the hot resistance is too high.
