using silicone on the manifold before the O2 senser is a no no

Anil_Sooknanan · Posted: Sat Apr 14, 2007 12:19 pm Post subject:

this is because the O2 sensor is the nose of the ECU and the chemical in the silicon damages the sensor so when buying silicon ask for the non RTV type silicon or O2 sensor safe silicon also raw oil and gas damages the sensor

never take off your battery terminal while the car is running

yea but what they don't know is the risk they just took ...
damage to the alternator , ecu, and othe electronic circuit in the car
what happens is that the alternator senses how much voltage is present in the battery and the moment yuh take off the pole the alternater senses a voltage drop sending the voltage pass 14 v

causing a high voltage surge which can blow the alternator regulator, fry the diodes, and f**k up your ECU and other electronics that work with 12 +/- 2v this happens so quick you don't even know if your ah costom doing this you might realize your changing or repairing your alternator more than normal the trick is to use use a jumper and 3 batterys hook the jumper to a load battery and to the terminals ( the battery is in the car ) then take it out and replace it with the other so the alternator always senses a load ............... any way doing the way everyone does it does work but my info is just the correct way to do it Wink

^^
wasnt' disagreeing with you, just discussing common 280c practice.
next question, in a carbuerratted car........................apart from alternator. what other electronics are at risk?

well bro i forgot to say that this is mailly for internal regulator alternators but in cab modles the deck is the only thing i can think of right now you see those cars hardly use electronics compare to the EFI cars today most of the things here can be proven by doing research online

an alternator thats over charging also under charging could cause a lot of trouble

overcharging - mainly happens if the regulator malfunction or one of the feild coil shorts .. with a high voltage your Ecu is at risk also all electronic parts in the car and engine also transmission

thats cool i wanted to do something like that myself but parts is the problem so what did you use

^^lol the title does say your ideas and facts

good info here though

well guess i put d most stupid title well need a good name and for some one to change it for me lol cause i'm going to put more info soon

sensors and their uses

Anil_Sooknanan · Posted: Tue May 08, 2007 10:25 pm Post subject:

O2 sensor one of the most inportant sensor in controls the gas system .. when you start on morning the car uses the collant temperture sensor to predic the pulse lenght on the injector after the O2 sensor is used when the engine reaches opperating temperture the O2 takes over .. what it does is generate a voltage according to the gases O2 level . a good sensor should be between 0.4 to 0.7 it should keep changing to and fro .. a low voltage means to much gas high means to much air

Anil_Sooknanan · Posted: Wed May 09, 2007 11:35 pm Post subject:

my mistake should be this first

ECU - Electronic Control Unit , because of rising polution levels and gas prices around the world fuel injection is now used by every auto manufacture for better performance

what it does is sense everything happening and what the engine is using (amounts) eg gas , air , trottle position , cam position, exhause gases, coolant temperture, engine speed (rpm)
the ecu places all these signals to opperate hence if a sensor goes bad the ecu gets the wrong signal of whats happening so its not sure what to do

Coolant temperture sensor - most people (including mango tree mechanic) think it's just to put on and takeoff the fan No well it does that too but it's for cold start, it controls the fuel system depending on the engine temperture this is why new model cars don't have to warm up it just makes the injectors dump more gas untill it warms up .. the car uses this signal untill the car reaches opperatind temperture then switches to the O2 sensor for the rest of the opperation
