The requirements are in NCOP 14 section 2.9. It says that there must be less than 20mA leakage between the HAZV and the chassis. Since the chassis is normally 0V on the auxiliary ELV, that means that you need to have less than 20mA leakage between HAZV and auxiliary ELV.goingbush wrote: ↑Tue, 17 Oct 2017, 14:26OK thanks, where would I find the Australian requirements, other than NCOP14 ?
I cant find anything in there about isolation where it mentions auxilliary ELV , obviosly when I turn the car off the DC-DC converter will be isolated by a seperate relay , or am I missing something. ?
Can't test it with a DMM as it won't generate a high enough voltage. I think you'd need a megger? Electricians have them. I'd ask advice from someone more knowledgeable than me though, I wouldn't want you to blow it up!
