HELP NEEDED Regulator Wires Brown & Pink

Post by manx57 »

Hi, Could someone help me please am pulling my hair out!!

I have a replacement regulator which only has 2 x red wires, 2 x yellow and 2 x Green wires.

My bike has 2 x red, 2 x yellow, 1 x Brown and 1 x pink, I have looked through pages and pages of info on the regulator and cannot see any info on the brown or the pink wire. I know the yellows go together as do the reds and I believe the greens are both earth? It is the brown wire and pink wire which originally were in a rubber connector and plugged into the old regulator I have not a clue where they go. Any help would be greatly appreciated

You have 2 red and 2 yellow, a brown and a pink wire? That's interesting as those are the colours that can be found on the 907IE.
According to the wiring diagram the 906 would have 2 pink, a red, an orange and a red/black, a light blue and a brown wire.
Is there anything stamped on the regulator/rectifier, a model or number which could help identifying it? If not, please post a picture.

I think that any modern reg will require a bit of wiring modification . Paso has a couple of extra wires , one for a voltage sensor ( which can cause excessive charge voltage when the wiring gets a bit tired ) My paso has a honda reg fitted .... not by me but its worked well so far .
I cant remember exactly how a modern reg is wired in but there has been plenty of discussion and tips on the subject , maybe do a search and look in the faq's but dont give up it aint that hard when you know how . :)

I use a shindengen fh012aa regulator, I have only connected the 2 pink from the generator and the red/black and the black wire to the battery. It has been running great for a year now. Down side is you will loose the charge dash light.

small led voltage meters are a cheap and easy fix.

There's no problem so bad that a little fixing can't make it worse! : )
If it ain't broke keep fixin it till it is

I used a charge warning light on mine wrhen I changed the regulator./ Rectifier

No problems and working well so far, fitted the unit in place of original bulb and retained with a spot of silicon

I gave up with the regulator I had and returned it and bought one which has the same black connector as mine.

Now I have no spark at all, which is strange as before the reg failed it was running well.

I sent the ECU away to Carmo for test which came back with no faults found! I have 12v at the ECU and at the coils, also the sensor test is 720 ohms but no spark.

Where do I go from here lol

Sorry for late reply. I think the coils are normally live when ignition is on ie they have 12volts supplied from the ignition switch , the signal side is tthe earth through the ignition module so if the ecu earth connection is not good or non existent then that could be the cause of your problems

Also if voltage to the ecu drops below about 9v the unit wont work ......properly.
It only takes one dodgy connection in the circuit from battery to coil , and it does a couple of laps round the bike gettin there.
The coils are 0.3ohm , I thought it was a misprint but they are def 0.3ohm....not 3.0, and the coils are powered direct from ignition 12v and the earths are switched , as mentioned above . Hth
