Replace Turn Signal Flasher

[RJUnsinn]

Hi Everyone...

I saw a similar post to this one two years ago (2004), but no one ever posted a definitive answer.

The issue is a faulty right-turn signal... As in the older post, the right turn signal went out on my 929. When I try to use it, the under-dash flasher clicks like crazy but neither the outside signals nor the in-dash turn indicator lights up.

The left turn signal works fine.

When testing the 4-way flashers, the flasher unit also clicks at that high rate of speed, the left lights blink as normal, but (as expected) the right ones do nothing.

After testing the front/rear right sockets with an electrical tester, I have decided the most likely candidate is the under-dash flasher unit... I'd be happy to spend the few $'s for a replacement, but for the life of me, I can not figure out exactly where the flasher is located. I can feel the physical pulse of the flasher under the dash, but the space is so cramped, I can't get my had all the way in. (Crappy design.)

Does anyone know if there is a "trick" to getting the old flasher unit out and the new one back in again?

Thanks!

RJ

if ya left hand side flashes like normal then it isnt ya flasher can..as the flasher can works both left and right turn circuits as told by the combination switch.

the right turn signal circuit sounds to be the issue.

the flasher can flashes to a rate of the amount of earth path it has been switched to. thats why if you blow a globe it flashes faster. this also lets you know there is a problem.

couple of things to look for (in no apparnet order) -

1) remove all globes on the right hand side that are part of the right hand side flasher circuit and test them for resistance. if they are open circuit = no resistance at all then replace the ones that are stuffed.

2) check the plug for the combination switch on the steering column to see if the pin in the plug hasnt been pushed out which will break the electrical connection. also check all plug in relation to the circuit to see if that has happened as well..

3) get a test light and connect the earth of it to a good earth source. put the pointer into the globe sockets.
if it flashes then nothing is wrong with the actual circuit (this test will also mean you dont need to do point 2 if point 3 tests ok)

4) disconnect and clean all earth points that are relivent to the circuit. reconnet after cleaning connection point and apply an electrical contact grease to the earth point before rebolting it to the body. this aids in stopping corrosion and give a better earth connection..

hope this helps

any certain fixes for this issue..cuz this just happened to me the other day..

no there isnt unfortunatly.

its a process of elimination and finding ther problem and fixing it.

bump!

This is quite a helpful post. Well, my uncle is having problems like this on his turn signal and he is really having a hard time to pinpoint the main cause of the problem. Anyway, this instructions looks interesting and I'm gonna share this to my uncle so he could try it out and hopefully somehow it would solve the problem. Thanks for sharing this. I'll appreciate if anyone could suggest another solution or a DIY on this.
