Title: Battery dead from rain
Post by: ArchRider on August 10, 2019, 05:47:58 PM
I rode my 2001 to work one day and it sat in the parking lot through a massive thunderstorm.  When I went to leave, it turned over and away I went.  2-4 miles into the ride home, I can feel a small surging and notice the tachometer has completely dropped off.  Then the speedometer begins to drop from my speed to zero and jumps back up again repeatedly.  I get to a stop light and I can tell that it's lagging like it wants to stall.  I give it a little throttle and it stays running but now the tach and speedo are showing zero even though I'm running, but it's still surging.  A couple of miles later I got stopped up in traffic and the minute I pulled in the clutch, she dies.  I try to restart but it won't even try to turn over.  After pushing it a fair way to get it out of traffic, I got a jump from a power bank my wife brought to me.  I still had to keep the throttle open a bit to keep it from dying again.  I got it home and hooked it back up to the battery tender and now the tender is showing the battery is charged.

I'm figuring I have a short somewhere and the rain made it worse draining the battery to zero.  I have heard that motorcycle are not like cars in the sense that they need the battery more while running and a dead battery will cause a motorcycle engine to stall.  My question for the forum is how do I go about chasing down this short?   :m I've never done this before and don't know where to begin.

Not sure if this helps, but these are the same symptoms I suffered when my Reg/rec went & fried the genny on my Blackbird. Different bike I know but the symptoms are likely to be the same for most bikes.

I would check the output from the genny first. Not done this myself on a Tiger, so unable to tell you how, but I'm sure there must be instructions on the forum somewhere if you do a search.

Found this thread when searching. half way down P2 it describes how to check the genny.

Thanks, Lee.
I was hoping this wasn;t the case.  I replaced the R/R awhile ago with one far better than the OEM.  At the time, the stator checked out when I performed a voltage check.  I'll have to find someplace where I can pull it apart and check it again.  I no longer have a garage (at least unitl I can gather the funds to build one.)

I left the bike on a tender and after a day, the battery was charged again.  I was working on it this weekend and went to replace an out headlight.  When I pulled the bulb, it didn't appear to be burnt.  I swapped the bulbs left for right and the same one (rider's left) was still out.  It does come on if I switch to high beams and then the right one goes out.  I'm really confused now, but have to wonder whether this electrical issue isn't contributing to my dead battery.  After I put the faring back together, I took it for a ride.  I was only gone for 30-60 minutes.  When I returned, I shut it down and tried starting it again.  It had enough juice to turn the engine over, but not start it.  Clearly the battery is being drained and the stator can't recharge it.
In full disclosure, 9-10 years ago, a mechanic jumped the headlights so that both of them would burn all the time when running on low beams.  Since it has been nearly a decade since it was done, I don't think this is the issue.
I'm going to have to check the stator, I just didn't want to pull it that far apart yesterday.  And if it is the staor, I want to ensure there isn't some other issue that is causing the stator to die.  I'm pretty good with wrenching, but when it gets into the electrical portions, I'm operating at a deficit.

Put a voltage meter across the battery terminals
Start it and see what the voltage is at idle
You should see 14 volts with it running ....if you ain't got 14 volts your stator and or reg/rectifier is toast usually need to replace both

Most all efi engines  ,cycles atvs etc etc will kill power to the brain when the battery goes below 11 volts

I have in the last couple of days had a guy from the 1050 forum contact me about a mates 955 human nature being what it is no one wants to spend more than they have too.

My journey had a distraction with me introducing a lithium battery to a new RR and they didn't get on..... in the end got fed up and changed the lot (including the recently fitted RR) alternator/RR/ battery and it's been happy days since.

Old tech doesn't seem to like lithium batteries. Blackbirds were the same, reg\rec & Genny did lithium batteries in very quickly. Can't remember the exact reason but seem to remember lithium batteries prefer a cleaner, more stably charge than old tech can provide.

Check the Electrex site their RR's have a health warning about mixing such with lithium.

OK.  This is all good information.  I'm going to check the terminal voltage and see what I get at idle.  I replaced the R/R awhile ago with a much better, but maybe the stock stator killed this one too.  I really hope not.  Stators aren't cheap and they're buried down in there.  I currently don't have a garage where I can leave pieces all over. 
And what of the one headlight that just suddenly went out?  I determined it's not the lamp, so it must be something in the wiring.  I've been wondering if that's where my battery drain is located.

Start with the relays for lights ...
I've had them fill up with water from rain .
They dont work so good wet...
Lol
The relays will be your headlight problainem
And maybe the battery drain...

Mustang,
Thanks, man.  Good idea.  And a new relay is a lot less expensive than an alternator.  Which, I think is also toast.  I checked the voltage across that battery terminals while the bike was running and battery was charged.  12.25V.  Not good.  I replaced the R/R with a Rick's several years back, but I'm guessing it could have also been fried by a bad alternator.
I looked at the schematic for the alternator and there are two parts on the list, alternator and stator.  Would I need to purchase both?  Or is the stator part of the alternator and comes with the alternator purchase?  Please excuse my ignorance.  I haven't dug this far into the electrical yet.

Is there a relatively straight-forward way to check a relay?

I'm certain now that it is my stator.  I check continuity between the three windings through the stator plug and it showed all three were dead.  Then I went and checked my Haynes manual and it mentioned that during stator replacement, a mandrel is to be used to keep a gasket from expanding.  It isn't very clear as to what this gasket is for and how to use a mandrel to keep it in place.  What have other people done in this situation?
Other than that and the "extractor" needed to pull the stator, it sounds as though this is a fairly easy replacement.  Can anyone who has replaced theirs offer any additional tips?

Thanks in advance

I think you  are talking about the O ring oil seal. If you've got everything ready and you do the change quickly ( by that I mean don't go have lunch half way through) it'll be OK.

Thanks, Bixxer.  I guess if things go sideways and I don't get it back together fast enough, I could always leave it apart and get a new gasket.

What about the "extractor"?  Do I need a special tool to pull the stator out?

No, stator should come out fine with your hands if you give it a firm pull.

Its the Rotor you need a puller for, not the stator. A tip for putting it back is to get some long threaded bar same thread as the stator cover bolts, 3 lengths about 6" long, wrap the exposed thread with plastic tape and screw them in lightly to the case at equal intervals, this makes it a lot easier to line the cover up and keeps the gasket in place when your fighting with the magnet pull, then just replace with the normal bolts once its home.

Oh yeah, the mandrel is for the Rotary Breather seal. New seals come with a plastic mandrel in them to keep the shape. If your motor starts burning a lot of oil thats the first thing to look at

Just done stator and regrec on my Blackbird. The, Electrex world one's lasted 12 years, twice as long as the original Honda ones.
Elextrexworld still do the best fault finding procedure around. Their late model MOSFET reg rec now connects direct to the battery to remove any weakness in the bike loom. Pretty much the "Stretch" mod tbh. It also comes with a plate to mount it with the airflow going through the fins instead of 90 deg to it and there's a video showing how to solder as well as crimp the connectors. It's almost as if they read our posts😂😂😂

I sucked it up and realized that this was going to take far longer than I wanted, especially when I don't have a garage in which to work.  So, I supported my local Euro bike repair shop and had him do it.  He also installed the Sasquatch mod while he was replacing the R/R and the stator.  Runs like a top now.  I hope to be able to run this Girly until she's completely worn out now.

:thumbsup good man.

My Steamer will probably still be going when I'm not, OK I'm not riding a lot before anyone chips in  :blah
