RB25det FIRE?????

[twincamgts]

I just finished my swap into an s14-go to perform koeo-fuel pump comes on I disconnect relay retest pump still comes on unplug from pump retest-my 2 rear brake lines melted ??? I have been trying to figure out- I installed my battery in the trunk-but I used my jump pack to try and start and put the neg cable on the trunk latch. can anyone help w/; any ideas of what it could be. I am a big AE86 guy trying something new.

my head hurt when reading that, wtf.... I think you're just brain-dumping, but stop the run-on sentences. it's not helping people understanding what you are trying to convey.

anyways, you got fire in the engine bay from your brake lines? that's all i got from what you said.

[Joe]

OUCH my brain hurts

what the f*** did you say?

[USMCgetsome]

joe you have to edit your own post! lol!

When I turned the key on a couple of seconds later my rear brake lines got so hot that they started to melt, the only thing that is hooked up right now is the power wire from the engine bay that supplies power to the starter and the fuse box in the engine bay. I checked all over the rear for a wiring issue-did not see anything, at this point my fuel pump comes on w/o the relay in place, so the fule pump is getting a power source else where, the swap went in w/o a hitch, now I am having a problem starting it. Did that help u in any way????

Can you take a picture or describe how/where you attached the ground wire in the rear.

To the brake caliper? lol

Time to start at square one and figure out what mistake you have made. Trace the wire and figure out if its chafed through and rubbing metal or something like that.

Ground wire comes to mind for me as well, but the brake lines catching fire makes no sense at all. I mean, they are rubber!

Question????The Rear Brake lines in the BACK of the car?Or the Rear Brake lines that connects to the Brake Master Cylinder up in the FRONT of the car??

I'm kinda baffled that Rear brake lines just MELT.... They have no power.They only carry heat from the Brake Caliper/pads.

What I'm thinking happened is that you started the car without the Turbo Elbow on.And the hot Exhaust is melting the Brake lines up front. By the Brake Master Cylinder.

Maybe you have some wires wrapped around the Brake lines that shorted out...

I'm not exactly clear.

Do you have any pictures?

THEY ARE BRAND AGENCY 300ZX CONVERSION LINES, ITS THE REAR LINES THAT CONNECT TO THE CALIPERS AND I INSTALLED A BRAND NEW BATTERY CABLE FROM FRONT OF CAR TO REAR AND INSTALLED GROUND CABLE TO CAR. IAM BAFFLED AT IT MYSELF-DID NOT TRY TO START CAR ALL I AM DOING IS CONNECTING THE POSITIVE AND NEGATIVE CABLE TO THE JUMP PACK AFTER 3 SECONDS YOU CAN HEAR THE LINES MELTING-I THINK I AM GOING TO BY A GROUNDINK KIT BUT AT A LOSS RIGHT NOW-ANY IDEAS?????

[Sil240]

OK well you Obviously have a SHORT.Disconnect The battery and pull out that Positive cable you just installed.Maybe somewhere along the line it chaffed and is grounding out.

[twincamgts]

JUST PULLED OUT CABLE AND IT IS ALL IN ONE PIECE-COULD IT BE THAT I DO NOT HAVE ENOUGH GROUNDS-THE ONLY THING THAT IT IS CONNECTED IS THE ENGINE BAY FUSE BOX,STARTER,AND BATTERY-WHAT ELSE COULD IT BE????

[Kansei240sx]

Start disconnecting everything along the path of the positive battery cable until your large amp draw goes away which is causing your **** to melt. As you go along the line disconnecting different circuits try it one at a time, and hook the cable back up. If you've hooked it up and the cables no longer get hot, you've isolated your problem.

Where is the negative battery ground located?

When you have the power wire go to the front for the positive lead on the battery, how do you have everything else powered up?

Does the power wire connect directly to the starter power wire, fuse box and alternator power wire? If it is, the power wire from the alternator needs to be ran through the fuse block.

You need an alternator ground, battery neg - ground, fuse block ground and ecu grounds.

P.S. I know he doesnt have perfect grammar, but even i could understand what his first post was about, you dont have be such douchebags about it, maybe if you got past bitching about something retarded and tried to actually read it you might be able to contribute something to someone who needs help.

[USMCgetsome]

also, are you sure your putting the terminals on the correct post? red + black -. This too will also cause some issues.

[mott6904]

Im still baffled how the rear brake line could just melt.

[twincamgts]

I figured it out-i got the car as a rolling chasis so I went into car blind-on the s14 engine bay fuse box there is a post in the housing that looks like where you would run a ground cable to it-so I had a ground cable to it b/c I didn't knowbetter b/c there was no motor and this my first Nissan I am a die hard AE86 guy-just wanted more power-so in short that post was a live and me thinkink it was ground when I grounded the chasis I charged the chasis and b/c my battery is in the trunk the reaer brake lines were the closest things to melt-

-triedt to start-nothing what are the wires that need to be repinned-also my wipers are working w/o them being activated

-ANY HELP WOULD BE GREATLY APPRECIATED-THANKS TO ALL THAT TRIED TO HELP

[240z4u]

Whoa, thats not good.

Check ALL your wiring man, you don't wanna find issues after your finished. Same with fuses.

The wiper harness is in the KA engine harness btw, so that needs to be connected.

snap a few pictures. it's obvious that your wires are crossed. you have a truck battery relocation, so how is wired to the engine bay ? follow he brake line. stop connecting the battery or the power pack, you can damage ore other electronics. re evaluate at the point that connects to the batter and to the engine bay area, fuse box, etc.

[tek747]

That sucks! Hope everything works out good....... but i might have to add, its definately one of those "DaZed aNd cOnFused" situations!LOL

[S14-NEO]

sounds to me like your setup is searching for a good ground cause there obviously isnt one on your current setup.. you should have at least one very good battery to chassis grounds (CLEAN), as well as a good engine to chassis ground (CLEAN)..meaning NO paint in between contacts..youd be amazed as to how many people have grounding issues when the contact isnt bare metal...ive seen it countless times..

[SullivanRacing06]

hey guys mabey this as smart as the guy that posted " dude a 12.8afr is rich, a 14.7 is the perfect afr!"

who let this guy work on cars, hahahaha
