I need help guys...

[punchy]

hi  guys,
          I'm at a loss as to the remedy for this.... i just fitted another reg/rec (3rd one), everything running and charging great, 15 miles into my trip and the charging indicator (kuyreakyn) light went off.. then the amber warning light went off then finally the battery died...no power to start the bike..Had to get assistance to get my self/wife/ and bike trailer-ed home...put a fresh battery on and she fired up, but not showing any charging lights, and was draining the battery...  when i put the flattened battery on my multi-meter it was showing 11.45 so was not completely flat ????
                               Urgent help would be appreciated, thanks. Punchy.

Re-check all of your connections.. The terminals on the connectors could have been damaged (overheated) with the failure.
Otherwise (and it's rare) you want to check out the stator. (Consult the shop manual for the checks on this)
OR - Maybe you got a bum regulator..

If the wiring looks ok I would suspect the stator they can go bad and it may have been a bad rectifier.

well guys, i left the replacement battery on wiggled, push and pulled the connectors and fired her up, charging lights on so i presume i had a loose connection ... thing is, when i put the battery back on that was in place when she cut out (reading 11.46 when tested ) wouldn't turn the motor, not even tried. The lights came on and that was all.. Just wondering if you think the battery is knackered ??

The old battery may only be discharged.  I would check the fluid levels (assuming you have access to the cells -- not, of course if you have a sealed unit), then charge the battery with an external charger.  If it still won't start the engine, I would either discard it or have it load tested.

hi guys, i got the battery load tested and it was no good, think the old rec/reg cooked it (replaced rec/reg).. got a new battery, checked the wires and connectors fired her up.. charging good, between
12 - 15 1/2 on my gauge.. got her fired up this morning and a red light came up on my gauge indicating
that its starting to over charge.. terminals were warm to... any ideas ???? dont want to ride her in case i cook another battery...Help

You may need a new regulator/rectifier.  There are two failure mechanisms on these units.  The series diodes can fail, in which case the unit does not charge (there are 6  of em, and a few can fail so it does not charge well.  The most insidious failure).  There are shunt units that short the outputs from the alternator at the correct point in the cycle to supply only the current required.  I am reasonably sure that these shunt devices have failed in your unit, allowing it to charge for all it is worth, all the time.

On the other hand, you say you have a new reg/rec.  What brand?  Where did you acquire it?  I suppose it was faulty at the outset, but this seems unlikely.  There appears no place in the wiring where this type failure could originate.

I am really puzzled about your unit failing in the wintertime.  The usual killer of these units is heat.  Several of us have relocated the units -- oops, are you riding a 1st gen bike?  The R/R on these is properly located for good cooling.  The 3rd gen bikes mount the R/R under the battery box, right behind the engine.  While I have experienced one failure on my 3rd gens with the R/R in the original location, the relocated ones have yet to fail (fingers still crossed!).  If you will check the other threads on R/R, you can see how this is done.

hi, i got the reg/rec from my local bike shop, gonna check the systme from end to end..

[punchy]

hi, i took everything electrical off that was'nt needed, the multi meter still shows
that its charging at 18-19 volts . . help . .

What Lawrence said... I had a regulator that over charged the battery, dried it right out.

[Jerry G Turner]

I would take the rectifier back to the shop where you bought it see if they can test it for you.

Make sure you use an OEM unit, less problems, some have used aftermarket ones with mixed results.

hi,
    as soon as the weathers fit im takin the bike to my local shop and gonna test the generator
see what its kickin out . . its only quarter of a mile away. .

[lragan]

If you have a meter that is anywhere near accurate, your R/R is bad.  18-19 volts will cook a battery in short order.

[TLRam1]

It is called a regulator for a reason and it's not regulating.
