yo

I just have recently swapped a sr20 into my s13 I wired everything up and test started it.. worked perfect up until I Relocated my battery in my trunk installed my turbo timer and boost controller. now when I hooked the battery up and went to start it I blew the ignition fuse ... WTF is wrong?

 

You obviously shorted or hooked up incorrectly a "switched" + wire. Meaning...when you turn the key to "on" it has +12volts. Retrace the wires and all the connections to make sure NONE of the positive wiring is touching ground. Once you do that, repair it. I'd start with the turbo timer, then boost controller, and lastly the battery. Check all your ground connections while you're at it too. Best of luck in your quest!

 

Start from the beginning and work your way back to the battery , you have a connection wrong some where .GL

 

thanks for the replys, im workin on it....

 

I now have figured out that the main ignition wires are grounded through out the whole entire car like i have tested both sides of the connecters on the engine bay(grey ones) and they both are grounded ( I figured this out usin a multi meter) but I still cant figure out where the hell i grounded them too.......

 

success I have fixed the problem I had to run a new Ignition wire from the grey conecter in the engine bay to the connection right under the steering colum. BaMM!! engine cranked , fuel injected and then turned over. Beautiful! Only thing now is I have no Rpm signal , tach, or fan? anyone kno

 

Perhaps you blew another fuse elsewhere or the wire you replaced also tapped off to those components. I wouldn't know with out having a wiring manual in front of me. If you do, look at what wire gives them their inputs and trace them back. Use you multimeter to check the power coming out of them.

 

It makes sense if the Main Ignition wire has to be wired into the acc relay.. Now I just need to figure out which wire it is that has to be spliced into. Its the same Idea as the fuel pump being wired into the Ignition ..

Thanks for the Tip!

 

No problem...let us know what you find out.

 

I figured out that the Acc relay is blowin I removed it and gave it a shake and could hear the pieces inside flyin around So I went into Nissan yesterday and Ordered up a new Acc relay which was 40 bucks (****) and I figured out that The Ignition is wired into the acc relay 100 percent and that wire was also shorted so I cut that wire and ran a new one. Everything should be good to go when It comes time to put that Acc relay back in..... I hope

 

The relays have moving parts.... Maybe you just heard the contacts moving around?

 

I Have figured out why I have no acc power the reason is because the Main ignition wire (black/red) needs to be wired into the ignition wire running into the cabin of the car(black/red) it connects to the ignition relay behind the fuse box under the dash right beside the clutch pedal, I have learned alot about wiring doin this swap .. good education for the more to come
