Flikering lights
My car (1997 Saturn SC2)'s lights flicker constantly.
Supposedly, I recently had my alternator changed out, after it abruptly died on the highway. My car has almost always had some kind of flickering light problem, but in the past months its gotten worse, and is exsecially worse over 55Mph and when I tap the brakes (And sometimes the battery indicator light will flash on.) In reference to what lights flash - all of the interior ones, and the exteriors at as far as I can tell the "pulse" of my car (piston fire). When using my cd player hooked up to the 12volt lighter port and tape player, it makes a high pitch whine that gets higher and louder as my car revs up, if this helps. Anything is exteremly appreciated. PS - My ground wires have all recently been cleaned and the battery connectors are not corrroded either, but after cleaning my car seemed to work 'normal' for a while. |

Sounds like a bad voltage regulator.

Wow, that sounds sadly simple. Other people suggest that it could be

Saturn utilizes a built in voltage regulator located inside the alternator.
Since the OP said that the problem predates the recently changed (new? rebuilt? used? tested???) alternator, I suspect that the problem is elsewhere. The OP unfortunately did not say how long he has had the car or when the flickering light problem began or of the frequency of the flickering. He also does not say the age or condition of the battery, many electrical problems and failed starters and alternators are due to poor batteries. What killed the original alternator? Since cleaning the battery connections and ground seemed to help, this is an indication of the place to start troubleshooting . Perhaps it is a bad cable or wire other connection. I suspect that this problem will require a LOT of time to chase down.

The whine you hear in the CD player might just be alternator noise and can
be remedied with a hash filter on the power line. Could also be from the spark coils but that's unlikely. One thing that since you changed the alternator, I should mention what happened to me similarly. I had changed the alternator on my chrysler minivan after the second Nipondenso alternator (original equipment) burned up. I replaced it with a Bosch unit which had higher output. Unfortunately, while it performed its task beyond expectations, it created noise on the radio that could be heard even with the volume way down. Traced this back to the type of diodes used in the alternator (avalance rectifiers) that are lower loss but switch very fast and tend to put spikes on the electrical system. I added a filter to the alternator output which cut the noise significantly. Yes, I read that you checked the ground connections. There are a slew of them too and they can drive a tech nuts trying to find a bad one. It is often better just to add redundant cables, for test, at least. A little corrosion on a ground wire or body stud can make for an unreliable connection. Big one to check is the battery to engine and engine to frame electrical connections. Other than that, have someone watch the lights while you start tapping about with a rubber mallet and wiggling harnesses. There may also be some problem with the through the firewall electrical bundle or fuse panel. See if the affected circuits trace back to a single fuse or to a common ground lug.

Good tires and battery needed for good service.

If its more than 5 years old a new battery is likely needed... My experience (which is Canadian climate related) is that almost any car will give safe and acceptable service IF you make sure you ALWAYS have enough clean oil and coolant AND a GOOD battery and in the winter only use tires (all season radials OK) with GOOD tread. (In the summer the tread is not as important so I like to keep a spare set of rims so I can use worn tires in the summer and new tires in the winter.) Brakes are always important. Lots of electrical problems can be caused by waiting for a battery to fail before replacing. Most good batteries will last 5 years but any more is borrowed time, better to save old batteries for spares or summer use in non esential vehicles. Batteries are cheap compared to starters and alternators and are much easier to change. A cheap new battery is usually better than an expensive old one, and price is seldom an indicator of quality. just my .02 >> Since cleaning the battery >> connections and ground seemed to help, this is an indication of the place >> to >> start troubleshooting .

Sorry, I've had my car 1 year.
What killed the original alternator was driving with all of the accesories on (wipers, lights, air, radio, and then breaking to shut off cruise control) As for the battery, its about a year old as well, since when I got my car, I kept forgetting the lights on (the bell only sounds when you start the car, no other time! Another problem I'm investigating now that I have free time)) I dont have a load test tool...how much are they, etc? I dislike the type of battery I have now as it is not the "maintence free" type. I recently checked the water levels and they were fine. I'm thinking about changing it (already in my next paychecks spending) along with plugs, since I was foolish to ever try Bosh platinums...

Like the alternators, batteries do not seem to like really hot (or cold) climates.

I have the same problem I started the car then disconnected the positive
cable to the battery so car was justed using alternator turned on lights still flickered tried stop lights stilled flckered and dimmed for a moment. should a good alternater not do that when not connected to battery. or is that normal when just running on alternater peter "HyperCube33" > wrote in message ... > My car (1997 Saturn SC2)'s lights flicker constantly. > Supposedly, I recently had my alternator changed out, after it abruptly died > on the highway. > > My car has almost always had some kind of flickering light problem, but in > the past months its gotten worse, and is exsecially worse over 55Mph and > when I tap the brakes (And sometimes the battery indicator light will flash > on.) > > In reference to what lights flash - all of the interior ones, and the > exteriors at as far as I can tell the "pulse" of my car (piston fire). > > When using my cd player hooked up to the 12volt lighter port and tape > player, it makes a high pitch whine that gets higher and louder as my car > revs up, if this helps. > > Anything is exteremly appreciated. > > PS - > My ground wires have all recently been cleaned and the battery connectors > are not corrroded either, but after cleaning my car seemed to work 'normal' > for a while. > > |
