Interior/exterior Light Flickers While Indicating

[Charles89]

For some reasons, when I'm driving at night (with my parkers & HIDs on), my parkers/HID/dash/gauages lights just flickers when I'm indicating. And my voltage meter in my R34 just jumps up and down.

Anyone know why?....

I did a test on my battery with a multimeter.

When car is off: 17.3v

When car is on: 20.8v

When my driving lights are on: 20.8

When I indicate with driving lights on: 20.0v

Not sure why the readings are so high, as I've been told the voltage should be around 12-14v. And the reading on the multimeter is different to the voltage gauage I have in the car.

Any help on this would be awesome!

did you have your multi meter on the right setting? the V with the dotted line. if you had 20v you woulda blown the ass out of your cd player etc by now. does it only do it when indicating in one direction or both?

Hmmm.... I think I had it on the right settings lol, I'll do another check.

But nah, it happens when I indicate left, right and hazard lights too.

if you are getting 20v then you have a serious issue. i'm suprised nothing has blown yet. my grandparents camry had the voltage regulator let go and it was charging 18v at idle and it blew a heap of bulbs (i think only the interior light and the glove box light were about the only 2 that didn't blow), fried the wiper motor even though the wipers weren't turned on, and a bit of other stuff.

Basically, the alternator can only just keep up with the demand for current. When you turn on the indicator, it's the "straw to break the camels back", and the indicators "steal" a bit of current from all the other electrical items.

You might need to upgrade the power of your alternator.

im sure a gtt would have a 70-85 amp alternator. HID,park lights,indicators and engine management would only be about 20-30. otherwise everyone would have the same problem...

Sorry guys, I just tried checking another car with the same multimeter and it seems like it's reading high as well, so just ignore the 20v readings.

But all in all, the voltage shouldn't just drop about 0.8v when I indicate anyway, should it?

I was thinking it is something with my alternator as well, because the lights flickers more when I'm in idle.
