Its a part under the hood that you can bypass. its like a fuse. its on the passengers side by the shock tower in a box with stickers on the top remove the one that the cover says it "BAT"(should be black and grey) buy a new one or bypass it(Y)

I think you may have destroyed your battery or the electronics?

First check your fuses are all good

If that don't fix it.

Check the voltage of battery Red to + Black to -
Meter should give a positive reading say 12-14Volts DC

If this is what you get then you may need a Auto-electrician to check electronics and wiring.

I have a 1985 nissan 300zx i installed the battery backwards, now the wipers,dash instruments,power light motors,and turn signals do not work


Check your fuses. You probably just blew a fuse. Worst case scenario would be your ECU is burned out, which is highly likely if the fuse didn't blow quick enough.

You blew a fuse. Im guessing most likely culprit is a fusible link. try both sides of fusible links found by your battery. both sides should show your approximate battery voltage. check all fuses especially ones that show power regardless of the ignition switch being on or off.

I need to find the ecu relay for an 86 Nissan 300zx.


The ecu is probably under the passenger seat. The battery also has a fusible link which may be blown. Also follow the battery wiring to the regulator box. This may also be faulty

Sounds like you had a weak battery,and now it's a dead battery. Go get you're charging system checked. Auto Zone does if for free. Could be an alternator too but it most likely your battery. And they'll put in your new battery for ya too. FREE!

Good luck

What did you wire the neon's to? Obviously whatever you wired it to overloaded the circuit and popped the fuses. Check you fuse box on the inside of the car. You should wire the neon's power directly to the battery. Don't forget the fuse shortly after the battery!

300ZX wont start, or crank for nothing


The car seems to have functioning parts but it is probably a wiring issue - have you done a heater core replacement or anything under the dash/hood in a while (other than "tapping on the starter" <-- which you shouldnt do by the way)

what year is it??

if it is a 1990 the car has a plug undone under the driver side steering column on the "security" and "ignition" wiring circuit - read your FSM (factory service manual) and diagnose the problem. it is definately a short somewhere!

No dashboard lights or windshield wipers.


I had the same problemon my 87 model z. If you are looking at the front of the car THe battery Should be one the left. Just below the battery there is a little black box with some diferent colored wires in it. The one closest the the front of the car(SHOULD BE GREEN) is called a fusible link. You cant tell if its melted by the naked eye most likely, but if you pull on that wire i guarantee that its burnt. Touch the two burnt ends back together and vialah, everything cuts back on. Make sure your battery wasnt installed backwards. That was the reason mine blew.
