Title: Rectifier Question
Post by Tanker2Biker on 05/15/10 at 12:26:15

I'm working on an install for some new, ballistic nylon saddlebags. They are pretty big, and attach to one another with two wide velcro straps. I am thinking about putting the straps under the pillion seat, but if I do, one of the straps runs right over the top of the rectifier. I tried it for size, and the seat will fasten down over it, but I want to make sure that I am not generating a problem. I see the fins on the top, which I would guess are there to help cool. If I put the strap over it, will it:

a) keep the rectifier from being properly cooled, and damage the rectifier
b) cause heat build-up that will ignite/melt the strap
c) both
d) neither, but something else unpleasant
3) nothing, it will be fine.

Any help appreciated :)

Can you unscrew the rectifer and run the strap under it. Then re-attach? I moved mine into the airbox which is another option.

Since it is under the saddle, that is why it is called a rectum fryer.
I moved mine forward towards the battery box with no cooling problems. I think your nylon strap would not allow it to cool enough.
I would suggest moving it forward.

Some have said that the rectifier needs to be mounted to the fender as a heat sink, others have removed it and located it in the air box. I guess that the question is not "Will it work", but "for how long"

by design... very little air flow under the seat.
leave the rectumfryer on the fender and put the saddle bag over it.
to be certain, go ride for an hour, whip the seat off and feel the b'tard.
then repeat with the bag over it. If it's notably hotter, I wouldn't cover it.
now if it is hot, check your battery often as this is usually noted on bikes that are battery killers.

I like this idea, but I have not been able to get the rectifier off, which sort of eliminates any of the solutions offered.

It has 2 crosspoint/Phillips head screws/bolts. I have tried them with a screwdriver with a square shaft, and a pair of vice grips on the shaft. Still no go.

So for now, I'll either put both straps over the seat, or one over and one under. I'll try that for now, and think about it some more later.

I'll post some pics after I get things under way.

Try an impact driver on them bolts, then replace with Allen head stainless.

The first set of bags that I put on my bike, would have laid about half over the rectifier, so I trimmed a couple inches off the sides of the straps, so they were able to ride behind the rectifier, and I don't think I lost any strength. My current set fit right behind the rectifier without any issues, luckily. I wouldn't cover it up too much. Even if it doesn't hurt the top of it, hanging down over it would also restrict air flow from the sides, which I would have to think wouldn't be good. Just my 2 cents. Do you have room to trim the straps?

I did get it loose finally, and put the straps down under it. I looked at the bottom of the seat, and noticed that the design has a cut out in the rigid seat form for it, so I just put the seat back down and let it "trap" the rectifier in that space without restricting the airflow around it. It sits on top of the strap seems to work fine.

Apparently it doesn't generate a lot of heat or they would have put it somewhere that has better circulation. :)
