I've been noticing for a while now, and it'* getting worse that my turn signals barely blink. It only happens when I have my headlights on and when I'm at a stop. If if start to go, they will flash a little faster. If it was the flasher relay, they wouldn't flash at all right, or it wouldn't be only when I'm at a stop. Ideas?

Ah. You have an SSEi. This means you don't have a voltmeter. This means that your alternator is probably on its last legs, and you haven't noticed it.

Seriously, you might just have a really tired turn-signal flasher (assuming you have the correct bulbs in your turn signals and none are burned out -- doublecheck that), but the slowing down of turn signals at idle usually indicates that your system voltage is getting a little too low, so you might want to see what voltage you've actually got at idle. Bonnevilles like to eat their alternators so you might want to see how yours is doing -- get it bench-tested, for example.

Couldn't it also be a bad ground in the circuit?

Doubtful. If so, its flashing rate wouldn't vary with engine speed. It sounds like what'* happening is that the alternator can't keep up with the load at idle, and the (by now undercharged) battery isn't keeping up either.

To rule out a ground problem, just turn on the parking lights and the four-way flashers, then get out, walk around and verify that all bulbs are getting brighter when they're supposed to. Any that are going _out_ when they're supposed to get brighter (i.e. the front parking/turn signals and the rear tail/brake lamps) do indeed have a bad ground.

I had the alternator replaced less than a month ago, I hope it'* not that! I'll check all the bulbs and the flasher itself. Thanks!

What were the circumstances? And do you have a new or rebuilt one now?

All that aside, you could have a bad one anyhow. They're relatively easy to replace, and a proper output test will tell you if this new one is really working or not. (Mine is on alternator #4 at 11 years of age and 112K)

Low on Blinker fluid maybe?

Seriously..sounds like voltage drop to me, my old silverado does that and they speed up if I rev the motor just a little

Well, trust me, i've gone through 3 since september..... the altrenators can sometimes be defective.....

LOL!


That happens with my Bonne Also. I asked a dealer by me about it and they said it was normal. At idle the voltage drops down because the alternator isnt spinning as fast. plus your foot is on the brake, which also drains more voltage from the circuit.

Did you check your blinker fluid? Also your transmission may need to be rebuilt if this persists..kinda sucks

SORRY lol i had to, for bordem sakes...right?
