Any One Know Of A Good Electronic Repairer?

[Cubes]

He ppls.

I'm after a good some one who's on the ball electronics repairer...

[sinistaGTR]

whats broken im an electronics technician

[Cubes]

I did something stupid... Very stupid.

It was a little dark and hooked up the new battery reversed.

It touched sparked and I instantly pulled it off.

She blew the main 75amp fuse and a 10am fuse in the car, the 10amp fuse has something to do with the dash lights as they dissapeared but now are back after replacing the fuses.

There's no pfc display and no fuel pump prime also.

Car spins over but she doesn't fire.

I've noticed there's no more relay click down near where the ecu resides, I have a bad feeling its the ecu.

Damn friggin stupid me.

[sinistaGTR]

Hey mate.

OUCH lol.

have you checked all the fuses near the steering wheel. possibly there may still be a fuse blown there thats why your fuel pump prime may not be hapening and no display on your power fc. double check all of them. if not doesnt sound good. but all your fuses are there to protect that sort of short. if not maybe your ecu. but yeh double check all your fuses and let me know how you go.

cheers dan

[Cubes]

Will double check.

I did rip them all out one by one but have plenty of time on my hands so I will do it again.

I've opened up the ecu and nothing appears burnt, I've looked real closely at everything and it all appears aok. Doesn't mean it is though.

Why don't car manufacturers slap in a big arsed diode to protect the stupid. argg.

Here's the other thread with pics.

I've got another ecu to test but can't get my hands on it until next thursday.

[sinistaGTR]

yeh i know.....

and yeh doesnt mean the ecu isnt fried, but a power surge like that should fry something enough to make it visble. but i have blown a fuse once before and power fc wouldnt turn on, no fuel pump, thats why i said that to start with. but yeh double check it and let us know,

goodluck dan

[Cubes]

Thanks you give me hope.

[Cubes]

I've taken a heap of pictures of the pcb so if your interested I can email a whole heap or how ever.

After a little looking I came across whats circled in red.. I'm quietly confident this would have saved the PFC.

As you will know if you read the previous thread the RB20DET PFC is nothing more than an RB25 PFC thats had a couple of ecu pinsouts relocated.. Which is a well known wiring mod if you drop an rb25 in to an R32.

[sinistaGTR]

do you have a multi meter do a diode check on it, and does that come in from a power input????

[Cubes]

It does come in from a power input.

How would I do a diode check? An ohm check to see if current flows?

[sinistaGTR]

yeh thats your best bet, my multi meter has a diode checker on it, just put your probes either side of it and see what it reads (try them round both ways aswell). see what ohms it reads.

[Cubes]

Its 100% a diode though as it has the little diode picture underneath it.

Damn Cubes bad luck..... hope you haven't fried your wallet on this one too.

[Cubes]

Damn Cubes bad luck..... hope you haven't fried your wallet on this one too.

hrmm yes.. Quite embarrassing really.

[Cubes]

I spotted this while going through a heap of photo's I took.

Hrmm.. by eye it looks as if a machine did the cut, using the camera it looks like its blown. ?

What does this look like to you?

Even if it is the throttle switch power supply (pin 57) I don't understand how that will simply stop the pfc powering up, but yes.. Most likely another fuse I missed.

[Busky2k]

Well if its that TPS track thats blown, chances are, the whole thing is stuffed because its not exactly directly hooked up to the battery if you get what I mean

Oh Cubes what have you done!

[Cubes]

I hope not.

This has to be THE most stupid thing I have done. Too busy flying around like a chook with its head cut off.

[Cubes]

The throttle switch power supply does see 12v. Oh well I'll get it repaired and fingers crossed it starts to work... I doubt it but.

Oh well.. I'll throw an rb25 pfc in to it.

Have you plugged the stock ECU in mate to test if it is the ECU or not?
