Maintenance: Battery

[BlackSamurai]

That is why those new Hyundai Car all proudly stated that their car comes with a Motorola microchip that able to shutdown and conserved battery when long period not using. Take one brochure from Hyundai showroom and you will see what I mean.

sharon, is it possible for you to share this with us?

Yu, why so many fuse covers missing?

 

[BlackSamurai]

Yu, is that a Mitsu fuse box or Hyundai's ?
hahha

 

[Daniel Lee]

God, I pray to you that Yu's is a Mitsu fuse box so I don't have to worry mine.
hahahahahaha..............jk...jk...

 

[Yu911]

hahahaha....... this is Hyundai fuse box.........! Looks like some 1 is worry, better open up ur fuse box & check ohh.... I have change 2 fuse before, the 2 also missing out the cover.:mouth_closed: Any 1 missing the fuse cover too?

Yu911,
don't tell me that you are using mitsu engine on a hyundai fuse box? If that the case then it could be the alternative and voltage regulator is pumping diff rating to your hyundai fuse box. But Daniel you got to keep an eye on the starter relay and MFI relay these 2 are the culprit when the car can't start.

 

[BlackSamurai]

Yu, I'm surprise to know that you are using Hyundai Fuse box for 4G63T
I only open it once, which is 2 years ago, when my hon is not functioning. (Too long never use hon )

 

[Daniel Lee]

Wah, I haven't check my fuses in the fuse box for years.
Only wipe the surface of the fuse box everytime I clean my engine bay.
Must check it when I'm free.
Any tips on how to check those fuses?
I'm not so good when it comes to this.

 

[Yu911]

Yes, I'm using mitsu engine on a hyundai fuse box, looks ori mah.
Ace, I have this problem before I change my engine.
I have change my air-con blower too, maybe I use longer time than u all?.....
Don't u all have this problem?
my air hon is not working few day ago, Ah Min check for me & it's hon relay, change 1 new, no charge, I think Ah Min is sot sot de, I said to him I must pay, just tell me how much, he say no charge, I still want to pay, so he say RM1, than I say don play play lah, so he say RM2, till the end I pay RM2, I think the relay must be dammmmmm cheap or he is sot sot de

Yu,
Thats why you have this relay problem. I actually sort an advise from one of my local sifu that are expert in electronic relay, alternators and has over more than 20 years of exprience.

What he advise is don't buy those super cheap relay as it is very hard for one person to test whether the relay is healthy or not. A lot of those relay has very low tolerences. he even show me a full box of faulty cheap relay which looks very very new. He said those reliable relay usually cost RM14 and above with proper box and manufacturer print and brand.

There are actually 12V and 14V option. Conti Car are all 14V so I actually bought these 14V relay for my aircon, horn, blower (even it is still ok) but original Hyundai OMRON for the starter (because faulty and blady RM50). He say those 14v can be use as it has higher tolerences. You know lah we usually have zero knowledge in this kind of stuff. So just follow his advise.

[Yu911]

u r right, last time I only use boss relay, but my friend say the ori relay from car is better than the after market relay, every time he change engine he will keep all the ori relay, may be is the ori used relay he give me, must check with him.
The red colour 90amp relay is not cheap, if I'm not wrong 1 cost more than RM60

 

[Ace]

yeap..agreed with yu. reliable relay usually cost a lot more. But the looks of your red relay is the type like our MFI relay which have even higher tolerences where it need to supply huge amount of juice to the starter and elec ignition coil. You can try touch the wire after driving a while and you will feel very hot on the wire.

 

[Yu911]

never touch the wire before, but I know is very hot, the ori wire at the fuse box is harden liau.
The red relay input & output conector point is very very big, normal clip can't clip to it, must use a big clip to do so.

 

[Ace]

yu,
looks like all your stuff is big. engine big, rim big, tyre big, horse power big even relay also big. heheheh what else ah?

 

[BlackSamurai]

big spoiler, bigger PCD. Hehe

 

[Daniel Lee]

Yu, your disc brakes got big big one ah? kekeke....
