Connected Battery Wrong Way Around

[barnoon]

Well guys.... I opened the PFC up when I got home from work just then and was greeted by the extremly stong smell of burnt out electrics, so my worst fears have come to be, while I cant actually see anything on it burnt it has the very distinct smell of when electronics are fried.

Is it possible to have these things fixed does anyone know of anybody in the Sydney area that can fix them?

If not what are my other options I cant go back to stock ecu as I have aftermarket turbo, injectors, z32 afm etc etc.

Thanks

hmm that sucks. You can go back to standard ecu if you want they can be remapped. since its an rb20 you have buckelys of getting a pfc for a decent price.

btw putting the battery terminals on backwards is only dumb, not stupid. leaving a washer in the intake when you bolt it back up destroying your motor AND turbos is stupid.

lol..

No fuel pump buzz, no pfc h/c display, car cranks for eternity; sounds very familiar.

Don't ask how I know this but take it to an elec. shop with the ecu pinout and they will fix it. Should cost around $100 to fix.

From memory the resistor on the main line is the one that dies.

Also check the main 75amp fuse within the engine bay relay box; that 'should' also be blown. The 75amp fuse isn't cheap either.

RIP powerfc

i know the shipping cost will probably double the price, but there is someone on Ebay.co.uk selling the fuses for £2.50 each...

i bought 2 30A from them and they are selling all for the same price.

Haha Cubes you did the same thing did you?? Yeah after closer inspection I discovered the the 75amp fuse was blown managed to pick one up from Repco for $11.

Now I will look into getting it repaired I hope it isnt too far fried beyond repair, does anyone know where I can get this ECU pinout so I can take it to an electronics shop with me?

[Cubes]

I've attached the ecu pinout.

Thanks Cubes

BUMP: Can anyone reccomend a place for me to take the PFC to to get fixed around Sydney?

Was talking to my old man about this one, he is a micro lecy from way back. he was saying that all cars have whats called "crowbar" protection, bascially there should be so many fail safes and stuff between the bat and your ECU that it shouldn't be damaged.

if your low on cash is prolly worth really getting you hands dirty, err dirtier... then you already have to find whats let go between the source and ECU.

i wish i knew more about your problem and PFC's to offer better help, hope its not the worst case situ

Hey mate thanks for the suggestion but I have tried the PFC on a mates R32 and it doesnt power up on his at all either so its definately the PFC.

And cheers for that link Cubes ill contact them soon.

[Cubes]

Thats correct but unfortunately with the skylines the ecu most definitely does get damaged.

In the process it also blows the 75amp fuse as well as one of the fuses under the dash. I forget which one.

Luckly the ecu blows the main resistor and protects the bits within.

Also note that the thread op could smell an elec burning smell so it has obviously been toasted. :S

yeah, thats a awesome way to check it , sucks dude was hoping it would be something more dispoable for ya.

so its abit of design floor then, thats pretty off Jap design.

[Habler]

Any updates on the PFC? Im in suspense!

[barnoon]

Haha nah not yet im taking it to get looked at tomorrow arvo so keep your fingers crossed for me.

I know this isnt any of my business, but i wish you best of luck in the hope that this can be fixed for you

Cheers.

Hey thanks alot mate... I dropped the PFC off yesterday to Automotive Service Solutions who specialise in fixing ECU's, they said they would give me a call over the next few days to say weather it can be fixed or not so ill keep everyone updated once I find out.

[BNR32t]

Yeah that sucks dude,

As was said eairlier, its not an engine... Just an ECU. Thats something to be happy about.

Hope for the best but expected the worst.

Good luck mate

[barnoon]

Alright guys I have an update,

I got the PFC back from the repair shop today, put it in the car it turns on the fuel pump primes the hand controller comes on etc, but the car still just cranks for eternity and will not start, ive checked all the fuses 1000 times and their all fine. Anyone got any more suggestions before I burn this fu**ing thing.
