GS1100GL 1982 - Turn signal, (Indicator) Problems

Hi all,

I had a major problem on the way to work that meant by the time I got to my works the battery was nearly flat. Whilst at work I charged the battery. On the way home I noticed that the indicators were lit permenantly when operated by the control switch. By the time I got home all the indicator bulb filliaments were blown. I then replaced the stator and the regulator to sort the charging problem out and that side of it is now fine. the problem is the indicators have been completely dead ever since. I swapped the flasher relay out but still nothing. the self-cancelling has never worked so that module with all the wires coming out of it, how does it work? can it be bypassed? Can someone describe to me how to do it? What else can I check?

Toby
 
Thanks for diagram. So how does it work? Am I reading it correctly that the flasher relay is grounded via the TSCU thingy? So if I ground that side of the flasher relay it takes the TSCU out of the circuit?
 
Hi again,

I have disconnected the TSCU from the harness. How do I wire up what is left? There was a lot of wires coming from/ to that control unit?

Toby
 
The self cancelling have never worked since I have had the bike. The OEM Flasher relay has been replaced, by others, at some point, with a Halfords 3 pin HFU209 unit. This set-up worked until my electrical overload problem. I just wondered if I could bypass the whole TSCU thing completely without too much fuss. It is a second generation one with a single plug and an odd sepeate wire. I have tested the handlebar switch and that is fine. Any ideas?

Toby
 
I have a stock relay and TSCU available.
If you have power into the relay then it is fried as Jim mentioned.
 
Jump the plug contacts where the two prong relay fits and see if the lights light up. Do this with the turn signal on left or right.
 
Hi all, an update to my turn signal problem.

I put back the TSCU back with a replaced connector block as it all fell apart when I disconnected it!

I jumped the 3 prong connector block as suggested, and got the lights to light left and right correctly. I bought a standard 3 prong flasher relay from an auto store and plugged it in. It still doesn't flash or light up at all. I can feel the relay energising when I plug it in, but no flash.
 
Glutton for punishment are we?


Most any issue you are going to run into (including the current one) has already been answered.

The stock TSCU pulls a stock flasher relay High. Depending upon the flasher you buy (see this link), the flasher replay has to be grounded. That is what the TSCU mod is about; getting the correct polarity of the flasher control wire. There are also two wire flashers if you never plan to have the TSCU working again.

Sorry guys, I seem to be annoying you all :-( . Excuse my ignorance. I was just trying to solve my problem using the existing set-up. Unfortunately a previous owner had modified the wiring by installing a 3 pin relay base and he had run an earth to the chassis from that, therefore bypassing the TSCU earth. The +VE (orange) is common between both the relay and TSCU as per OEM. I just thought as it had worked before my electrical melt down, it should work again the same when I replace the flasher relay. I was just trying to understand what the TSCU actually did as there are a lot of wires coming from it and the switch block.

Well it is obvious you keep trying. If you read the link posted from above most is explained in either it or the other links that it links.

The OEM flashers and the Variety of newer flashers are all different as explained in the link. If you have the correct flasher the PO mods would probably work.

I went back to review this thread (started 9/4) to see if I have been "too harsh" on the OP. Well I'm more stupefied than ever :( . The OP has repeatedly done things counter to what is written in the links provided and "guess what???" he still can't get it to work. Surprise Surprise. Maybe another 100 posts will help.
