2008 gen2 regulator/rectifier?


New member
Does anyone in the Courtenay or Campbell Riverarea have a spare test regulator I could borrow? I'm having an issue with either my alternator or regulator. When the bike is running warm and I have my high beam and my heated grips on, the voltage sometimes drops below charging. Not always, so the voltage is fluctuating.
Thanks, Brent

Not sure, I'm in Victoria. Don't have one other than on my bike. Could be the stator? Might need a high output one.

one of those mystical electrical problems

I understand the KLR only puts out about 210 Watts at about 3.5K rpm.

Headlight High beam 65 watts (110+ watts if you have both high and low on at the same time)
tail light 10 watts
heated grips 30 watts (maybe more if they are no name brand)
Misc other electrics 25 watts

So you are going to be demanding somewhere between 130 to 175 watts at 12vdc, you will not get that kind of an output at idle or low rpm.

Did you check your output at 3.5k rpm?

bad Batteries are notorious for burning up stators, and the connections. I know you KLR guys like to get big mileage out of tires and batteries. Have you checked your battery? easy to swap out for another known good battery and check outputs again, no risk of damaging a battery if the stator is wonky.

Let us know how you make out

I don't think anyone would want to lend a regulator, if there is something wrong with your stator it will likely damage the regulator.
