Battery drain.

[Vodka]

Yes, because we needed to measure lux intensity and room temperature all at the same time. The lux intensity x1 and x10 are inconsistent. Other than that, everything works fine.

EDIT: That multimeter is user friendly, the slots will lit up for you to know what socket you should use and will emit an audible sound should you put it on the other slot. Of course, this is not idiot proof.

yeah it's got everything btw this is the lux meter i use coz as is said i prefer separate devices. i like using the UNI-T in the middle coz it's so small. but the yellow one works just as well at just P150. even the calibration out of the box is pretty good

Im also a Unit-T user.

Hey! It has been a while since I saw you here. I didn't​ buy a dedicated light meter since I won't have any use once we finish our project so I looked for a multimeter.

I was hoping that it will be useful in a car but it turns out that it isn't. Well, a multimeter is still useful should there be a need for it.

I bought my car Toyota Altis 2002 A/T last Mar 23, 2018 with the issue of automatic lock on the driver seat. So the day I bought this we go straight to the shop and ask to install security alarm (I forgot the brand) then after 2 days the battery got discharge. The battery got replaced immediately and after 5 days the issue came again. It's stupidity of me not to observe the car on the first week before we install the alarm. Going back, we go the other shop to look the problem he told me that my alternator is worn out and we decided to replace it as well but it didn't resolved there. Our car is drained after 2 days
I did back to the mechanic he finds out it was grounded and remove the fuse connecting to the radio, clock, alarm and lights. So by that I am thinking maybe I got this to the shop where we install the alarm. We went to the shop and told the issue they turn off the alarm and back the fuse to observe. Then after a day or two the battery drain again. Its getting worst sheeez.
What i did is to remove the fuse and it works for me because I was using it for the next 2-3 months sacrificing without alarm, radio, lights and clock inside.

Then, I decided to go to another shop. He told me that there is no problem with my electrical maybe just the battery size which is Motolite 1SMF. He will back the fuse and advise to warm the car everyday for at least 10 minutes which I did unfortunately the battery died.

Mga ka tsikot hope you could give some advise or determine what specifically that problem is?

Thanks,

(Please refer to the hi-lighted sentence) i'd like to ask why did the mechanic just took out all the fuse where in fact he already determined that there was a grounded line? why didn't he fixed the grounded line instead?

[rod2924]

How do we know if the battery we buy is genuine brand new and not reconditioned. TIA

It should come to you, factory-sealed, with no wear marks. Everything should be fresh (terminals, case, labels/stickers). Most importantly, it comes with valid warranty documents that matches the serial numbers on the battery itself.

It would also help tremendously if you buy it from a legit shop.

[StockEngine]

yep authorized dealers only

He's expertise is not electrical but he know it's grounded. Only 1 fuse just took out connecting to the alarm, and etc.
Sorry for being a newbie here.

What you may suggest po Sir?

[dr. d]

bring the car to a proper auto electrician, where it can be properly trouble-shot.
personally, i find it difficult to drive around without in-car entertainment and lights.
your cigarette lighter is probably also out.

[Nikhoy24]

yes ang hirap! mobile phone and bluetooth speaker ang pansamantagal

[techglimpse]

I use in-car voltmeter for monitoring voltages and have an automatic car battery charger desulfator for maintaining battery health at home.

ano po ba dapat ang reading ng voltage nito? before and after magstart?

[red_one]

Before start = 12V and up.
After start = 14V and up.

When cranking, pag umabot ng 7V, palit ka na.

Actually, 9v lang palit kanna dapat. At 7v, swerte mo na magstart pa yan

Sa cranking lang naman, bumabalik sa 12V agad pag nag start na. Ü

Normal start sa akin 9V.
May scangauge kasi ako.

Ah. You use them obd testers. Afaik there are some delay in the reading there.

I use fluke true rms multi tester that records the highest and lowest voltages down to in millivolts and time recording.

actually maski 9v ang binaba pag starting, alanganin nag condition ng battery mo bro.
try mo muna i charge batt to full, then remove float charge; test crank ulit

[dr. d]

before starting, that's your battery voltage.
after starting, and with the engine running, you are now measuring your alternator's output voltage.

Sira ang charging system/ alternator mo.

After starting, Vo should be at charging voltage = 13.8V.

Kung 12V yan at cranking at 7Vdrop, battery lang ang tumatrabaho.

Have your alternator checked asap if you don't want to ruin the battery.
