DIY install Voltmeter

[khguan]

guys.. wat is ur car voltage when idle? wats de highest voltage u can get?

my car seems getting lower voltage nowadays... i guess de battery going to be dead soon.. altho i still can start my car smoothly without any probs..

b4 start its a bout 12V.. after start.. at idle its fluctuating from 12.5 - 13.5.. when driving.. it its at 13.5.. if at nite.. is lesser.. bout 13V.. i think it is very low...

any comments?

wait next time I attach my multimeter to the battery terminal, go one round KL and then i tell u :P

i think that is normal... above 14 consider battery kong soon eh... coz the alternator keep charging ur battery and like never full one. if didn't start the car and on light and music... the voltage drop then it means battery not enough need to charge again. (this is wht i think only... i dunno any theory about this)

i looking at the voltage at my audio capacitor... when off audio, 13.5v. On audio 14.4v.... b4 start car never see... cannot monitor every time.. coz it is under my seat. hahahaha.... i notice one thing... when off ignition key.. the capacitor looks like discharge back to the battery... voltage dropped to 8volt and off.

and i have a hard time to start the car... at least took me 1.5-2sec.

can anyone teach "how to install Vacuum and Oil pressure meter" in another new topic? Full process.... and also the volt meter as well. i need this 3 meter only.

so that my money won't eaten by the accesory shop and workshop. then can buy more things for my car. hahaha....

installation for voltmeter.. heres qoute from speedster_jg :

voltmeter where got complicated wan..... got 3 wires top n 2 bottom wires
TOP wire : red, black, orange
DOWN: red balck

orange = dimmer light, no need to connect wan oso nvmmnd

black + black connect to ground, any point of body oso can
red + red connect to power source e.g. cigi lighter.
done.

I guess we have all above DIY except oil pressure aye B)

Orange where to connect... i need it to dim at nite.. if not how to see road?
so bright!

where is the ignition wire? i wanna connect my turbo timer.. but dunno how... no diagram.. coz bought from chop shop.

 

[khguan]

noneed connect de orange wire lar.. brightness is fine for nite driving.. not as bright until block ur view.. just nice...

ignition cable u can tap from ur HU there.. or amp also got.. its de same line..

 

[artnet]

amp is remote wire coming from HU...

ermm... i guess for the turbo timer still go for electrician...

 

[khguan]

if u r not sure.. better let de wiring guy to do it.. better spend some money rather than screwing up ur car electricals..

 

[artnet]

ain't u suppose to support DIY...
ahahahaha....
just kidding.

 

[khguan]

yah...i truly support DIY.. wat i mean is not all ppl can do wiring properly.. if u r not sure with wiring.. dun play play.. u can just short-cicuit something in ur car..

n dat may cost u much more... rather then giving acc. shop do it...

u can learn from those ppl...then next time can DIY lor...

 

[artnet]

ya... i almost learn from them...
how to dismantle my car... hahaha..

 

[jaywat]

Better learn the whole process else don't know how to put back kakakaka :lol:

anyone else installed a voltmeter??

care to share ur car voltage when
1. idle (engine n battery cold)? - 14.4v (de highest achieved)
2. idle (engine warmed-up)? - 14.0v, sometimes down to 12.5v
3. engine off? - 12.0v to 12.5v (old batt)
4. when driving? - 13.0v t0 14.0v
5. at nite(with lights on)? - 12.5v to 13.5v

i noticed de autogauge meter readings is less by 0.3V compared to my cheap digital multimeter.. n de place i tap de voltage (cigarrette lighter socket) is lower by 0.2V compared to de battery terminals.. so i have to add 0.5V for de real voltage...

ehem, me back! :lol: :lol: :lol:
by ur reading bro, about 12V, a bit low la
but wats this 1-5 thingy? izzirt ur real readings? cos i read prevuiously u mentioned 12V plus minus then its low. u might need volt stabilizer, which i incidentally have oso :lol: :P :P
ok more serious, u got wat electronics in ur car ? just to check ur voltage requirement etc.?
if 1-5, then ur fluctuation a bit high lor

 

[jaywat]

khguan is the one selling VS lar :lol: :lol:

 

[khguan]

speedster_jg,

well.. de 1-5 is de real readings... (de meter reading plus 0.5v)

dat day when u test de meter u already said de voltage is low.. dat is due to de meter u seling me is less by 0.3V...

well i think its bcos of my old battery lar... wanto change it soon.. my battery at de +ve terminal there got a small crack liao... duno y...

 

[speedster_jg]

hehe yeah i know he custom made summore ma
i play play oni
hehehehehehe

the orange wire is for the lighting kan?or no need
