Re: voltage regulato

At a guess, probably inside the alternator.

Re: voltage regulato

If it is in the alternator, then I have a different problem. The battery isn't being charged. Tried a different battery, same problem. Volt meter shows battery voltage, the red triangle is flashing and the battery light is on. I took the alternate from my K1200s and installed it, didn't fix the problem. Any ideas?

Re: voltage regulato

Certainly not a known problem with these bikes.

Hopefully, someone with more electrical knowledge (or had same problem) will be along shortly.

Re: voltage regulato

I can't say I have more electrical knowledge but I'll add my 2 cents. I see your in HI but if your storing this bike and maybe start it up once in a while to idle, the battery will not charge and you will slowly drain the battery. Don't quote me but I think you have to be around 1700 rpms for the alternator to kick in. Don't know if this is your issue but I do like Odyssey batteries, their military grade and work well for me here. I wish I was there though!

Re: voltage regulato

Store a bike in Hawaii? I may not be able to ride too far, but I can ride all year around. No, it isn't charging. By putting the alternator/voltage regulator (if it is built in, and I think it is) from the S bike and finding the same problem, I think I have eliminated those two. What else is there?

Re: voltage regulato

When hooking up the bike to the computer and running the diagnostic software INPA, the engine BMSK has something called "alternator exciter field".

If the alternator is not "excited" by a 12v charge after startup it wont have polarity.

A reset of the BMSK may fix the problem.

Re: voltage regulato

Could also be the rectifier which is part of the alternator. The regulator is a square finned heat sink but not sure where it is

Re: voltage regulato

Did you check your alt. ground? You say the gen. warning light is flashing?, it should be "steady" on for a battery charge issue. any other warning indicators? 12v to the alt. maybe you issue, some are electronically controlled through the CANbus. Do you have voltage to the alt? some are switched to not allow the alternator to charge and drag while cranking, you may have to get the engine up to a certain RPM in order for the CANbus to switch and send power to the alternator in order to get it into charging mode, dont know if that is the case with this set up.

Re: voltage regulato

They are self contained alternators, there is a device called "over voltage protection" added to it. This shorts field voltage to ground if over voltage is detected, to protect things. This device could have failed (just a thought). It is about 90$. But I would give Motoradelectric a call and talk with them, call in the Pro's. If you need any parts they are the folks. I don't deal with anyone else myself. Okay, beemer bone yard too.

Re: voltage regulato

Got it figured out. The 12v wire between the alternator and the key / display has a short somewhere. We ran a wire to the 12v power port and cut the wire going to the key. Problem solved, idiot light shut off.
