Puretron polarity

[paulzy123]

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

Interesting because in all else...black is the negative or neutral wire [except when blue is used, but that's usually 240 volt stuff.

Hooked mine up yesterday with the black as the earth. It blew the air out the sides and sucked through the top.

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

Do you have the full wiring harness? I’m ordering one at the moment. Looks like it runs right down to the drivers seat and plus in down near there.

Haven’t got the harness no, I’ve taken the supply and fused it direct from the battery and put it on a switch.

All works well though, really pleased!

Gotta add at least 3rwkw! ;0)

Thank for your help on this.

Cheers

Paul
