Electrical - to heat or not to heat

zaga · Mar 23, 2009

I'm rewiring (rebuilding
the wiring harness) of mine 98 FE600E and I have a question, and I wonder if
you can help me.

In 98, I have the 2 yellows in short connected to a regulator and then a
rectifier;
In 99-00, there is a 3 phase regulator/rectifier with the 2 yellows and the
blue in;
In 01-02, there is 1 yellow to the regulator/rectifier to battery and
starter, and the other yellow with a regulator to the lights.

Is this change to avoid the heat related problems of the SEM? Because it
looks like if you donÃ‚Â´t have the lights on you are only using one yellow and
you get less heat ??

I was going to buy an Electrex RR13 three phase regulator/rectifier, but if
it will cause more heat I probably should buy a single phase Electrex RR02,
connect it with one phase, and buy a regulator RG12 to the other phase to
lights, like the 01-02.

It is confusing because in 03, last year of SEM, they have again the 3
phase reg./rect. like in 99-00.

What do you think is the best way to go ??
.

Please help me on this one.

Hi Zaga,

The heat build up thing from the alternator in my eyes is a bit of a myth, the main killer is heat from the engine along with the cheap enamelled wire the ignition coils were wound with.
I use high quality enamelled wire with a heat threshold of 200c so heat isn't an issue with reliability.
Which ever way you go with the reg/rec wont make any difference. It would be interesting to know why the factory swapped and changed them though, could of been a cost thing at the time.
Not sure if one system is more efficient than the other.

Regards

Sparks.

Mine is the older single Tympanium brand single phase regulator going through a separate rectifier that you mention.

Blew up a battery once and have had trouble with battery going flat while riding with lights on. I recently fited a voltage warning indicator light and it showed that the bloody voltage keeps teetering between too low & too high. Reg is gotta be dodgy.

I am about to chuck the standard reg and rect to the sheisenhausen and replace it with a three phase unit off a jap bike. They all look to do pretty much exactly the same thing - just different sizes, shapes & connection style. So far have TL1000 and RGV250 units - not sure which I'll use.

Anyone have any experience with how big a three phase unit has to be when run on the pair of single-phase windings in the SEM?

There are lots of 'em on eBay - the TL1000 one was AU$35. The cheapest aftermarket unit was about $75.

I'm going to try the RR13 2 phase regulator from electrex, costs about Ã‚Â£ 47,25.
I thik they are made by HPI - Horse Power Ignition in Belgium.
They say it works for the SEM.
I will let you know

Sorry its not 2 but 3 phase regulator rectifier

Hi Zaga,

Will be interested on the out come on this one, a 3 phase reg/rec needs a 3 phase balanced input which means each phase is 120 degrees apart..
Three phase motorcycle alternators usually have 18 poles, 6 poles to a phase and the coil pitch is every fourth coil, all the coil are wound in the same direction and are connected either in a star or delta connection.
The SEM stator is single phase but uses two circuits, the single phase coils are wound directly next to each other going clock then anticlockwise. This is true for the SEM but 6 of the SEM windings are wound in one direction and the and the remaining six the other.
The blue lead is the centre tapping, because they both wound in different directions you only get a voltage from each yellow to blue, the voltage potential between the two yellows is zero.
Does it actually state that the original Husaberg Reg/Rec is 3 phase, not seen that mentioned any where.

Regards

Sparks.

Just a tid bit here for what it's worth,

In 03 all of the accessory electrical power is taken off of the battery, and both yellow leads go to the reg/rect and the output goes to the battery.

Not that this matters to your problem, but, when I get the chance, I am going to set my electrics on my 01 to the same way the 03 is so that the battery gets recharged as quickly as possible.

As sparks stated, there is no potential between the yellows, so all one has to do is buy a universal regulator from Trail Tech and tie the two yellows together from the reg/rect, and connect them to the two tied together yellows from the stator. And then you have the output from both "lighting" coils going to the battery.

Dear Sparks
Could you please comment this, that I read in the 2000 Owner Manual : "NOTE ! The alternator delivers 70W in each of the yellow wires. Only one of these is connected from factory. Both wires only to be connected whenever in a need of more than 70W though this creates more heat which causes a higher risk of failure to the alternator."
IÃ‚Â´m sending this page attached.
Thank you
Zaga
