Hi
Have never found short on these ic's yet ...

How to know if they are giving problems ??? ( How to test )

I have about seven dead units i could not revive with my bit off knowledge on them ....

Bench test gets to pass on some off them but if installed on car it does not even start ... Can it be faulty 170v capacitor ????


I can upload video off last bench test i did .. but car not even wanted to start .....

hi
to test ic-s you measure with ohmeter about 600 ohm on capactor 10uf near 5v stabilizer 7805
~ 600 ohm is ok if you get something below ~30-100 ohm then you got a blown ic
i get them all desoldered and measure between pins 7 and 14 + and gnd (did not find other method....)

i had boards with those ic damaged which were blowing 2 x buz91 coil driver (edu draws about 7-8 amps for 5 seconds then blows buz91 an some printed circuit )

capacitor 10uf 450v should measure ~ 8-11uf low esr 0.00 to 1 ohm (various caps measured from an working unit)

if inverter works (you have 165v at capacitor) it doesnt mean the car will start , you have to check th bridge
and the connections between bridge trasistors 2xbuz91 and 2x 2903
also check 23p06v

some boards get intrerupted circuits on the inside layers of the board, so all parts seem ok the edu doesnt work; had boards which started working when bent by corners,

nice setup! i have the same problem, dont have spiil valve tot try i use light bulb
inverter works, h-bridge works if spill valve runs thats for sure
maybe something with engine speed signal from the other ecu?

Hello
marking code=sSD , sAK, sB1, S43 ?

all sot23. 3

help please!


regards

[Bllinda]

you here ....
sAK

[kenancatli]

Hello
I see not sAK!
sSD? And sB1?
sB1 = B1 it is same= bas40?
sKS=bss138n?

help
please
regards

[PierreTheron]

HMMMMMMMMMMMMMMMMMM

Mabe better try something else on google or download SMD values

[aitistu]

hi
AK= BCX70K
SD = BSS138
M02 = BST82

just to be sure for sb1 and s43 could you point the location on board? pictures with an arrow ?

sB1 = bas40-04v 2 x Schottky diode
s43 = bas40-04v 2 x Schottky diode

regards

please, where it should connect this pin
it's urgent!
thank you!

Hi
as any see this situation " see pic "
Is this comun issue , because is the 2st , I got here width this "blow" capacitador ,
Replace the capacitor is enough , because I didin"t see any thing more damage ?!2016-08-08 15.44.36.jpg2016-08-08 15.44.51.jpg

hi,
it is not capatitor it is resistor 0.5ohm.did you check fets because something is in short circuit
