Electrical Problem?

[popinr33]

Hey guys,

My problem, When my car is warm and running at 650rpm idle and i touch the accelerator very gently there is either a bit of lag before revs build, or the rpm drops to about 500. Same thing happens when i turn on my headlights or put my windows down.

Does anyone know about this issue and how to fix it?

Thank you

if it happens when you chuck the lights on or use the windows sounds like you're alternator might be on the way out

while the car is running put a multimeter across the battery and read the voltage.

it should be around 13.5V. if it's less then alternator isn't working properly, if it's more then regulator isn't working properly (which is part of the alternator anyways).
