OK everything is 99% set up, 30 and 85 have +ve supply and relay is working exactly as required. only issue is 86 has a +ve supply too, until it is earthed. im guessing this is where the "diode fuse" should be used, to prevent the power making its way back to the aux pin and damaging the unit. sound about right?
steve must be right - there seems to be no such thing as a diode fuse
is it just a standard diode i need for this? dse or repco can't tell me what any of their diodes do, only that they have lots in stock. it will help a huge amount if I know exactly what I'm asking for
and one other thing - can a standard relay be used to switch to an earth, rather than switch to power? seems to work, but any reason why it shouldn't be done?
30 - connected to chassis
85 - connected to chassis
86 - switch - +ve
87 - earth output
so 87 will only be earthed when 86 has power?
