Wiring up indicators on my Jota. Nice easy question

I'm with Brett. Hooking up a set of indicators should be a half-hour job at most. Given that you're struggling with this very simple bit of circuitry, it might be a good idea to phone a friend - someone with some electrical skill who can actually come around with a multimeter and look at what you've got. 

With the best of intentions from contributors here, It's damn near impossible to sort out electrical issues via internet. The best we can offer is educated guesses on what might be going on. It's a hands-on type of job to make any real sense of it. Do you have any mates with some basic auto-electrical skills? Indicators are pretty much the same on any vehicle so they don't need to be a Laverda expert. I used to live not far away in Chiswick, but I moved back to Tasmania a while back. Actually I was only 8 years old at the time, but I reckon I could have fixed it  :D
 
My humble guess is your trying to find and fix something that got completely removed sometime in the past. No tell tail ends of wire appearing from the dark depths of the loom.
 
It looks that way Vince. I have plenty of information here now from all of the kind contributors to help me sort it out. Electrics have always been a mysterious area for me but I will get there in the end and I will learn something about bike electrics in the process. I like to sort things out myself and learn. I will stock up on fuses first because I am sure a few will be blown in my voyage of discovery.
 
I remember trying to hook up my indicators again after a little strip down and tidy up and i couldn't for the life of me get them to all work properly when they were all connected up........the rears worked perfectly if i disconnected one at the front but connected up again they would just stay on,..as Dellortoman says it should be a half hour job but i spent ages rechecking the wiring,earths and everything till i was blue in the face  :-X and convinced that my wiring was correct................and guess what it was?......the newly purchased indicator i had fitted at the left hand rear had come with a 6 Volt bulb fitted!!!  ::)

Stick with it Mr Wrongtrousers  you will get there in the end.
 
Just to add and to start.....the single wire from the R/h indicator links up with the Light green wire coming out of the 5 pin plug from the speedo (ie indicator warning)...so you can follow that wire back till you come to a connector.

and the L/h indicator wire links up with the Black and white wire from the same 5 pin plug......so follow that back too.
 
Dear Wrong Trousers,
these might help...

What kind of indicators are you fitting?

If they're LED type, they are polarity sensitive and even if wired up correctly they are unlikely to work with the original flasher unit (unless the indicators come with built-in parallel resistors).

As Schurminater suggested, the original flasher relay is sensitive to the current draw, so will only work properly with two 12V x 21W incandescent globes each side. 
 
Hello. I am using standard indicators. I will be pleasantly surprised if the flasher unit works after 30 years of inactivity. I gather that its possible to fit a unit from an old 1970's car like a mini or some such if it has died. I think it is covered in some past topics, unless one of you fellows has the latest up to date information to hand.
 
If a 2 pin flasher relay is standard I would recommend fitting a 3 pin relay where the third goes to earth.
Gives a steadier flash rate, not rising as revs rise. (I have seen this)
The RGS and maybe later 180s used a 3 pin flasher relay.
 
This must be some sort of record for information/feedback just to wire up a couple of little flashing lights, God help you come Christmas :LOL: :LOL: :)
 
Those old flasher relays are reasonably simple and robust but they do fail occasionally. If yours hasn't been used for 30 years it's probably still as good as new!  But if you find the flash rate is too fast, too slow or doesn't flash at all, they're cheap to replace. There's a gazillion choices on ebay. Less than $5 will get you an electronic, load independent relay with adjustable flash rate!
 
Indicators all working fine now. That old flasher unit that has had a 30 year holiday must have wondered what hit it when it starting getting some power to it.

Yes, with hindsight it was very easy, but I learned a lot by gazing at the wiring diagram and a bit of trial and error.

Thanks to all who contributed.
