yeh hopefully Tony can shed some light on this. having a look at the wiring diagram now to see if the yellow wires coming out of the reg/rec goes to this connector that is now fried then into the alternator as the colours on fried connector are yellow as well as the reg/rec wires.ASTAR said:It looks as if that connector has drawn a lot of current and melted, this can cause the connectors to touch each other as the shell has warped.
Tony is the expert on Regs on these bike and I'm not sure if all of those three wires come from the Stator to control the voltage are all related as one.
Getting a higher voltage with 14v is normal as the RPM increases. The CBR alternator is an amazing unit considering it has a charging range from 2000 to 20000 rpm. I'm sure under a certain amount of load at idle it won't be charging at all though.
Yes true! But it's hardly efficient at low RPM. It's the same reason why Tony programmed his headlight kits to stay dim at Idle. Or try putting high watt lights in a CBR and see how far the idle drops at low RPM. The alternator just isn't setup in terms of output ratio at low RPM. But I guess the majority of my examples are based on load at idle - I’m sure it just manages to keep the battery charged without excessive load.sir.b said:Wayne: Semantics, but I believe the alternator provides power at all RPM's and loads, whether it's 'charging' or not is determined by whether the power from the alternator is greater than the current power consumption of the bike (which varies based on what electrical systems are running on the bike at the time).
I know I'm not telling you anything you don't know, just clarifying the point for the new kids :blush:

you learn something new everyday. i was under the impression that it didnt produce any power at idle. just to confirm, it does produce current but its lower than what the bike needs so the rest of the power comes from the battery?sir.b said:Wayne: Semantics, but I believe the alternator provides power at all RPM's and loads, whether it's 'charging' or not is determined by whether the power from the alternator is greater than the current power consumption of the bike (which varies based on what electrical systems are running on the bike at the time).

Yeah that's exactly right mate.robbie said:you learn something new everyday. i was under the impression that it didnt produce any power at idle. just to confirm, it does produce current but its lower than what the bike needs so the rest of the power comes from the battery?
but on my bike im getting 14.2V on the battery at 3000rpm but instead of it picking up, its dropping as the revs go up. i thought it was meant to get higher the more you rev, but it shouldnt climb over 15V or it would mean you have a big problem as well.sir.b said:Yeah that's exactly right mate.robbie said:you learn something new everyday. i was under the impression that it didnt produce any power at idle. just to confirm, it does produce current but its lower than what the bike needs so the rest of the power comes from the battery?
Here's the power output of a couple of alternators:
![]()
You can see that they start making power as soon as they start spinning, and that the power increases as the RPM's go up.

What you see in the graph isn't voltage output, it's amps. The reg/rec then regulates the voltage, so the variance you're seeing is probably (Tony will confirm and diagnose when he sees this thread) within the normal range of a reg/rec output. I don't think [email protected] is anything to be concerned about, it's not spiking/dropping all over the place, but I'm interested in seeing Tony's response.robbie said:but on my bike im getting 14.2V on the battery at 3000rpm but instead of it picking up, its dropping as the revs go up.
Ohh ok no thank you. I've learnt more on this forum in a week than I ever thought I could. Hopefully Tony can help.sir.b said:What you see in the graph isn't voltage output, it's amps.

Awesome to hear :headbang: It's good to get positive feedback from someone new rather than the normal "you guys are fucked, this place has the worst reputation on the whole internet" that we're used to :blush:robbie said:Ohh ok no thank you.

This is the best forum I've ever been on. It's very social and productive and very busy so you don't have to wait long for an answer. It's very active and everyone helps each other out. That's awsome!!

Hahaa... it's rather good, as some times I'II find a thread where a few people have already chimed in with answers. Sometimes it's even surprising the details rememberedsir.b said:There are a few guys on here that know these bikes like the back of their hand, once they've diagnosed problems a handful of times the rest of us plebs tend to catch on and jump at the chance to use what we've picked upThen a tricky electrical one comes along and everyone sits back and waits for Tony :blush:

Just read your reply, don't plan on getting out of here before you're 65.Eclipze said:So I guess I'II get replaced and retire sometime soonopcorn:
