My old rectifier burned out on me a week ago and i bought a after market one with the heat sink and i installed it and it's working fine it's putting out the right voilts and amps but it's getting really hot 160deg on the rectifier so does any one know how hot it's should be at?

 

What brand of aftermarket, electrosport? Because those are junk and will only last a few weeks.

 

The RR works by turning excess power into heat. It's normal for them to get hot and that's why they (the good ones at least) are finned.

 

I got it from http://www.regulatorrectifier.com/ca...ier-p-800.html

 

I do not know exactly how hot they are supposed to get. I thought about going with the electrosport model, but the advice from the forum on the R1/R6 model and the cost difference is what got me. The one I got from ebay cost me $50 plus another $2 for connectors. It is a really big unit (thats what she said) that is practically new so I hope it last for a long time. The main thing is that all of the weird electrical things have stopped.

 

Yes, regulating excess voltage via heat dissipation is how they work; however, I don't think I've ever heard (read) any temperature figure before in any of the ka-jillions of r/r threads from the various forums and email lists I've been a part of.

So, yours could be very hot or pretty cool, who knows, as we have no base line for comparison. All of mine get too hot to touch for any length of time.

 

Some people like to put a small cpu style fan on there to cool them a bit.

And the aftermarket ones are better than the stock honda ones, so don't worry too much about that.

 

I know there going to get hot but i just wanted to know if any one ever put a heat gun to it and saw what the temp was. I have a shop manual for my superhawk but it doesn't tell you how hot thay get.

 

So, how much VDC does it put out at what RPM?
