Hey, just got a simple question regarding the cigarette lighter of my S2 R33 GTS-t.

At the moment, I've got 5 gauges hooked up from the IGN wire of the ciggy lighter (boost, oil temp, oil pressure etc.) and I just purchased a iPhone car charger/FM transmitter which plugs into the cigaretter lighter.

So, my question is, how much power and current can the ciggy lighter handle before I start blowing fuses or buring things out?

Cheers.

check your ciggarette lighter fuse for rating , should be 15 amps which is Nissan standard size

so keep adding gauges and check current rating when running with multimeter to check for overload .

whatever the load you require, DO NOT replace the fuse to a higher rated fuse, i have seen countless fires in 4wd's because of people placing larger fuses in the system to accomodate the load when in fact its also the wiring that needs to be looked at. Too much load in the wiring system usually ends in a melted wire onto the chassis and fire, electrical damage and potentially a fatal accident if you are in motion

This is pretty much the rule with anything electrical

a ≤ b ≤ c

a = Circuit full load current

b = Protection device rating

c = Current carrying capacity of cable

I don't imagine a gauge will draw that much so I'd that circuit should be able to take it :)

id say ur gunna be well under the amp limit for that system but FYI stressed cables dont just melt ( unless extremely stressed)

if ur unsure about a cables capacity keep an eye on it, they heat up slowly if they are running too much current so you wont notice anything until the heat builds too much for the insulation then BANG... :O

    • Hello everyone. I believe I have s1 headlights but I just wanted to make sure and getting confirmation from you all. Thanks in advance for your help!
    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy.
