my 2000 civic si has some electrical issues... the car has a stinger battery which has more power than a stock one but its tiny... only electrical wiring it has is a clifford which works... battery and alternator were tested and work... now the alternator is not charging my battery... my headlights and dash lights dim when i press the brakes while the car is moving... the radio also powers off and on when i press the brakes... i took it to some old man who specializes in this and told me the battery is too small for my car but its at 100% and the amps are more than the stock one... he told me to put a regular battery and then bring it back... i dont want to spend $100 on a battery if mine works but could this old man be right? i dont understand how a regular battery be better then this stinger battery which people usually upgrade to since it has more amps that factory... any help?

try a regular civic battery then look for a homie with a integra or civic and ask them to pull it out and try it on u car, either that ur alternator is going out soon

Quick question for you then. Did you have these problems before the Stinger?

F4MzEkSOL

i never had a stinger but i think u should try a different battery, but i did had a bad alternator before, most the time when ur cluster lighting dims in ur cluster means its the alternator is going bad soon it might show signs of charging but in the near future its dying, most places check it and see it good but all of sudden it can fail anytime, i had kragen check my alternator they said it was good but it was killing my battery all the time, then they gave me a replacement now i had no more issues

Also check whether 7.5A dash fuse 15 is blown.

i checked the fuse 15 and 7.5a was good... ima try a a regular battery and new battery terminals...

what else could it be? i bought the car about a month ago and its been having these issues ever since...

Does the dash charge light stay on with the engine running?

With the engine off, what voltage do you measure across the battery posts?

With the engine idling with no load, what voltage do you measure across the battery posts?

With the engine idling with high load (high beams, rear window defogger, and max blower on), what voltage do you measure across the battery posts?

ill check this in a few... can this cause my headlights flicker and radio powering off when i hit the brakes?

Former User

What do you mean by this?

hialeahzbg

the voltage of the things u told me to check with the multimeter...

Former User

I would not suggest any tests that are irrelevant to your problem.

hialeahzbg

i meant can this battery issue be the cause of the headlights/dashlights/radio flickering when i press the brakes?

hialeahzbg

what should the voltage be for all 3 diagnostics be? so i can get a battery asap if all this fails...

Former User

Post the voltages and we'll go from there.

hialeahzbg

okay tomorrow morning i will get my hands on a multimeter so i will post them up..

i wish u lived in miami....

1) engine off is 12.67
2) engine idling is 12.68 after it warms up but starts at 13.50 and goes down..
3) engine on with everything on is 12.66

hialeahzbg

Tested it again and idling started at 14.34

With the engine on....the fluctuating voltage means the alternator is going bad. It should say consistent around 14.3 or so. The temperature of the car should have nothing to do with voltage.

hialeahzbg

So alternator is def going bad then? It was tested and came out fine...

hialeahzbg

Okay replaced battery to a autocraft gold and car idling stays at 14.34 consistently...

hialeahzbg

Now engine on with everything on it's at 12.61

hialeahzbg

But it's slowly going down... Now it's at like 12.40 after like 3 mins and it's still going down...

hialeahzbg

Now with the car on, radio on and headlights on it went back to 14.23... Thats with no AC on... With the AC on it goes to 13.74... If I add the rear defroster then it goes to 12. 91
