TT 600 electrical question

[Finster]

Hi , I've got a 1986 TT 600 that I am trying to get road legal , so need to fit turn signals and brake lights. Existing head and tail lights do work . Is it possible to do ? or would I have to get a complete wiring loom, stator and rotar etc. from an xt and try and fit that . Any help would be very much appreciated .

Well, in theory it can be done..
It's kinda of a matter if the rest of the electrics can

But you'll need several things as well..

I suggest you go for LED turn signals and taillight as well as they LED's take much less power (Watts) from the system and I suppose that just changing the taillight to LED will give you the rest you need!

Parts you'll need:

-Some cable lengths with at least two different colors and some terminal connectors
-Terminal crimp
-Light switch with turn signal button and horn!
-1 diode with two input and one output
-LED turn signals
-LED taillight (make sure it's an E-approved)
-LED flasher relay
-Some non conductive electrical duct tape: to put al the wiring together
And if you're extra careful you can add an inline fuse!

You can either tap into the existing loom preferably or make a direct connection to the battery in this case I do suggest using a fuse just to be on the safe side!

One more thing.. here in Portugal you need a working speedo and "dashboard" for the indicator lights (Max and medium beam and minimum if you got it, and turn signal indicator light) and a horn!

Plus, front and rear brakes both have to turn the brake light on!


If ya need help sourcing out the parts let us know!

Cheers for that Vando, this model does not have a battery, runs the head and tail light from the alternator, do you think it is still possible to do with its basic existing wiring ? Cheers

Hi!

Yes, I guess it can be done...
But since there is no battery, only when the bike is running you'll be able to use them...

Does it run From and To the alternator?
There should be at least a capacitor or a small battery to prevent overloads and/or to work as a ground, anything there?

What's the Wattage on the taillight lamp?
The difference between a normal bulb and LED bulb in terms of Wattage demands if I recon well it's about 50% less..

If you make a separate wiring for the turn signals and tap into a positive somewhere in the existing loom you should be able to power everything!
Do you know the exact amount of power your alternator produces?

As far as I know this model has a 6V system and was originally equipped with the blinkers and brake lights and a little battery. There is not a lot of power available, the original headlight bulb is just a miserly 11 watt!
When I was investigating on mine, I think it was an '85, I could not really find a wiring diagram so I made one myself - I could try to find it if you need it.
Anyway, I do remember that a part of the electrical system runs on AC current and another part on DC current, the DC part is probably blinkers. I assume your bike has been stripped over the years from all unnecessary items, but do you still have the rudimentary wiring loom that it came with originally? It'll be expensive I guess to buy all the parts from yamaha that have been taken off, so some DIY engineering might be in order.
If you go the way of etrofitting with a XT600 system, be advised that the CDI unit between TT and XT is the same.

Thanks for getting back to me on this . from what I can see the complete wiring system on this is the alternator, cdi, ignition coil and voltage regulator , all looks like the genuine wiring , no obvious signs of any tampering. Just checked the globes, the rear is a 12 V 21/5 WL and the head Light is a 12V 30/30 W . What do you reckon ?

Cheers Auke , have been told before that some TT models did have blinkers etc, I have seen photos but I have never been able to find a workshop manual for that model.

Sorry for taking too long.. it's much easier to draw this on paper than on Paint lol


This is the easiest way!
the R's stand for flasher relays.

I put two flasher relays in this circuit to avoid the fact that using just one, it would be always receiving charge which you don't want!




If you think or want to try using just one flasher relay, you can fit it to the cable positive cable that goes from the headlight to the light switch...

If you want to make a circuit so you have an indicator light for the turn signals I also have one already made up...

Hey Vando, "Thank You" for all the help , I obviously know practically nothing about electrics , so this is a huge help . Cheers

You're welcome!
