I spent some time today doing a nice sleeve covered routing up to the front, put an on-off switch in the top (inside) of the left pod. Connected directly to the battery with a 2 amp fuse.

After finishing up...I stood there and thought...looks good BUT...what if someone "accidentally" flipped the little rocker switch...probable dead battery...!

So...after thinking for about two minutes...I removed the rear body/tail and looked at the tail light.
Perfect...the tail light "tab" is outside of the housing. I widened a female spade connector wide enough to fit.
I ran the positive wire from the fan to the tail light +tab (proper name?) and plugged it in.

Great, the fan goes on and off with the ignition switch. A very simple connection.
The fans are rated for MANY hours, so with the fan on with the switch it's no big deal. And at .75amp draw, the system doesn't even know it's there.

I do think I'm gonna spring for a 30+cfm (currently 20cfm) fan shortly.

Despite the all knowing detractors...don't care, it appears to be working well.

Mike

It sounds cool man, but I must be missing something. Why did you put a fan on your regulator? Do they over heat?

Yes a couple of BWB'ers have converted to MOSFET style regulators because they are believed to have greater heat potential. The FJ1300 and R6 use MOSFET regulators.

The factory setup uses thermal grease between the regulator and frame. 1_mike has put a fan over his regulator to cool it down.

The regulator works by dumping excess voltage and current to ground (frame). Lots of heat is generated in the process but if it has no where to go the components overheat and breakdown. Things that make heat should be in an air stream so they can stay cool enough to work. This is where the a fan comes in as it keeps the air moving.
Buell is not alone with a problem like this.

But how do I overclock it?

Great question!

I think we must first figure out how to install Linux on the ECM...

How about some pics of the install?

No thanks, I would rather ride than sit on the side of the road trying to figure out why it randomly won't mount a NTFS volume. : )

Hahahaaha Nice one Froggy.

Imagine if that was the case and among other things we actually needed drivers for, say, those new Rizoma blinkers : p

Has anybody measured the case temp of the rectifer-regulator while riding?

Har har, those issues were properly dealt with years ago.

Linux includes drivers for everything you need. If a driver for your hardware isn't included, you don't need it.

At least when NTFS isn't mounting, its a problem and you fix it.

When a windows share isn't responding, it's because, well, nobody knows but it will get better if you reboot everything. Most times. For a while.

In my experience, Samba on Linux is more reliable then Windows on Windows.... Especially if you don't have a true domain controller set up for your windows network.

I think the ECM is a PIC microcontroller, so it has no OS, just a small boot loader and a big assembler program (that was probably originally a C program). Awesome little chips for the money.
