[TR] Triumphs Digest, Vol 15, Issue 104

[dave northrup]

The problem was no blinkers at all, no noise, no trafficator light.

I looked at the wiring diagram (duh!) and that really helped.  Plus I was trying to trouble shoot the blinker module, but made no progress there in testing various connections w/battery.

I cannot see the wire colors behind the plug where the module plugs in – its up against the side and there is sufficient crap around it to hide them.

After consulting the wiring diagram (again duh!) I realized how I could test it – by bridging the wires.  After using a test light to ascertain the power source, I found out that the “blinkers” work just fine, although obviously they don’t blink.   Now its off to a flaps to see if I can find a three prong blinker module, preferably analog, although I’ll go digital if I have to.

Thank you for your response.

Sorry if this has been answered, but I'm on the digest.  The green wire (X) should show battery voltage t if the key is on.  The Green/Brown wire (L) should  also show battery voltage if you don't have the turn signal on and then open and close when you activate the turn signal switch in either direction.  The Light Green/Purple wire (P) goes to the dash lamp and should do the same as the Green/Brown wire.

If you have the flasher out there should be continuity between X and L and X and P.  It won't go open until the current flow is high enough to heat the bimetallic strip and open the circuit.  An ohmmeter won't flow enough current to open it.

If you have a newer electronic flasher it depends on what kind you have.  Generally they'll start flashing as soon as there's any path to ground.

You don't want a "really" new flasher that fast flashes when there's a bulb out.

What's your problem?   No light?  Light all the time?

The blinker module on this car is likely not original.

It has 3 tabs, labeled L, P, X

I think its bad; seemed hot when I pulled it out after testing the blinkers.

How do I test it?
