Pb with Trailtech S8310

Hi

I use a stator Trailtech S8310 and have connected 2 LEDs xvision (10 watts each + all nav equipment for the rally : GPS, iritrack, etc...). My bike is a KTM 525 year 2007.

It workd fine during my previous rally (Heroes Legend in 2010) but during my last rally (Pharaons), I noticed the battery charging was not runing fine. Without the 2 Leds, it was even just for charging the battery...
I guess the stator and/or the regulator is dead.

Do you know how do I check the stator ? The regulator ?
Is there any specific test to do with this full DC equipment ?

Thank you guys !

Fred

If the stator is good and the regulator is faulty, the best choice for a replacement
regulator is a Shindengen MOSFET regulator as used OEM on the Yamaha R1
and quite a few other Japanese bikes.


I recommend this business ( below ) VERY highly as a source for a complete
Shindengen voltage regulator kit which is comprised of high quality wire, connectors, etc.


The business is run by one guy and he is very helpful if you need tech support,
which is unlikely because the installation instructions he provides are excellent.


I have one of his Shindengen kits on my KTM 950 and it works flawlessly.


Bonne chance !

Disconnect the stator wires (two yellow spade terminals). Attach a voltmeter set to VAC. Start the bike. Measure the output at idle and at high rpm. You should see about 20VAC at idle. Rising to above 60VAC. Also (with bike not running) check for short to ground on each of the two outputs. You should get open circuit.

Regulator doesn't tend to fail. What voltage do you get at battery, idle, idle lights on, 3000 rpm with lights on. Borrow a known good battery and retest if results don't look good.

Thank you guys for the answer.

I talked to Trailtech in France. I got some similar answer but the guy told me he is not really a specialist.

---> The first thing I will do know is to do the test you are recommanding.
---> Then I will open the carter to check visually how is the stator.

If the reg/rec is dead, I will consider I know the reason as it was in a unventilated area (behind the water radiators).
I will move it to a better place to protect it from over heat.

If the stator is dead, I will be embarrassed as I have no idea of how this could happen.

One detail: for the Heroes Legend I used a 4AH battery (stock KTM). For the Pharaons, I used a 6AH battery.
With such a 6AH battery, the time to charge the battery is longer.
Question: Is it possible that it made the stator providing charge for a too long time for each charging cycle and finally caused some pb to the stator ?
Traitech guy does see any pb, but my mecanics (not an electrics specialist either) said it could be a pb...

If you have an idea on it ... Thx

The reg/rec is pretty bulletproof. I'd be surprised if it failed.
