Jessica Posted January 19, 2014 Report Share Posted January 19, 2014 So, batteries rest at 12.8v, turn key to "on" position and it slowly drops to about 12.2v Volume at zero, heater fan off, But radio, a relay, and the 4 amps are on and of course the ignition coil too cause my car has no "acc" position. Anyone else have that happen? They come right back up to 12.8 afterwards. Maybe i just need to top them off on the charger? Cant imagine its a bad cell, the batteries are pretty new but i guess i could have them load tested but the car starts easy even on those -15° days we had so i doubt that. Just didn't think amps really drew any current at idle. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside. My super random youtube channel and terrible camera work.

alaskanzx5 Posted January 20, 2014 Report Share Posted January 20, 2014 maybe the fuel pump is turning on to. I know my key in the on position turns the pump on. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Jessica Posted January 20, 2014 Author Report Share Posted January 20, 2014 maybe the fuel pump is turning on to. I know my key in the on position turns the pump on. wel, yeah, the fuel pump does come on, but for only couple seconds until the pressure is built, then it shuts off. At least i'm pretty sure it does. The car is fuel injected so thats how its suppose to work, and i don't hear it running. I may check that though.

alaskanzx5 Posted January 20, 2014 Report Share Posted January 20, 2014 might be running at a low preasure to keep the preasure built up. like all things electrical even if they aren't being used as long as they are on they pull small amounts of power. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Jessica Posted January 20, 2014 Author Report Share Posted January 20, 2014 true, some cars recirc the fuel so the pump stays on and doesnt overheat. i'll def. check that in the am.

SnowDrifter Posted January 20, 2014 Report Share Posted January 20, 2014 Normal. You are turning in all the cars electronics/ motors/ lights/ gauges with the key on vs. just the radio and your amps ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...
Jessica Posted January 20, 2014 Author Report Share Posted January 20, 2014 good to know, Snowdrifter I never noticed it with flooded batteries, you know, regular maintance type. Since i have AGM could that be the difference? Or was i just not paying attention before? Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.

alaskanzx5 Posted January 20, 2014 Report Share Posted January 20, 2014 ^ using the same meter for both cases? if not could have been a difference in meter. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Jessica Posted January 20, 2014 Author Report Share Posted January 20, 2014 using smd-vm1 and double checking with my DMM, so yes. edit: re-read your question, I did have a different meter back then, Soooo, maybe? The old meter was accurate just not as fast, but this wouldnt require a fast meter to see. Rest in peace, walled 87 accord build log 03' Corolla build with AA Mayhem inside.
