92 civic si -- blinking battery light
ok this is getting really annoying the car drives and runs starts perfect the battery is new the alternator is new there is nothing wrong no problems but the dam battery light keeps blinking and i can hear somthing under the hood every time it blinks.. it blinks about every second for a peroid of time.. if i press the gas or brake it goes away and then comes back when i let go.. its just annoying theres nothing wrong with the car but i cant stand it anymore

Re: blinking battery light
Lol could your alt be loose? Doubt it but hell with a check while you are in there. It could also be your sense circuit lines check that your plug is secure. Good luck

Re: blinking battery light
yeah it has happened to me as well with a starter I got from Autozone and an alternator from napa. its hit or miss sometimes with auto part stores. im just saying to rule out the other **** first before you waste your time taking it all apart. good luck man

Re: blinking battery light
What car? A bad battery won't turn on the charging system light because this indicator light signals a charging system problem, not a weak battery.
1) Check whether the alternator belt and all alternator mount/bracket bolts are tight.
2) Get a multimeter and measure voltage across the two battery posts with the warm engine idling under no load (all electrical accessories off) versus under high load (A/C max, high beams, rear window defogger). Post those two voltage readings.

Re: blinking battery light
Yea check out voltages with a volt meter, might be easiest to get a cigarette lighter volt meter.
Keep in mind that some or all of these cars have an ELD (Electronic Load Detector (current meter)) in the fuse box and the computer will stop the alternator from outputting the normal charge voltage during certain conditions, to save fuel, such as when the car is travelling at certain MPH, engine temp, load on electrical system, whether the fuel is cut off to the engine... So the alternator won't necessarily be at the charge voltage of 14V or whatever all the time.
I'd check the resistances from the alternator to the electrical system.

Re: blinking battery light
ok well my battery voltage is jumping from 13 14 and 15 bouncing around pretty fast and something by my alt is making a high purring humming noise every half second

Re: blinking battery light
Sounds like a bad voltage regulator inside the alternator (<--- replace).
By or inside the alternator?
