Hi,

So I picked up my puretron a couple of weeks ago and have had a look and there doesn’t  appear to be any indication of positive and negative on the power cables for it  just a black and a grey cable.

My better judgement would say black is positive but I’d like to be sure as I don’t want to pop the electronics inside it when I wire it in. 

I’ve had it apart but can’t make out which is positive and negative as they are on a small connector that connects to the blind side of he pcb.

If somebody knows this one it would be much appreciated.

Thanks

Paul

Thanks guys, the thing that threw me was looking at the lambda sensor apparently the black is the signal and cream is the ground.

As tridentt150v says black is used as the nuetral in all other things.

I'll give it a try when i get home, Richmond98 thanks for the shout on that hopefully mine will do the same.

Cheers

    • I had never actually looked into it, but aren't onboard compressors a thing in trucks?
    • Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.
    • Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor
    • Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.
    • If that was the case I suppose you could call it "Mein's" brand....  ... I'll see myself out... 😅
