An electrical question for the group. I have set up the system in my RV6 pretty much per the basic AeroElectric Connection Z-11. I have put in a switch and diode between the main buss and the endurance/avionics (E) buss. I also have an alternate feed with switch through a battery buss to the E buss.
I thought
it would be a good idea to use a rocker switch with a light in it to indicate when I had the alternate switch in the 'on' position. This means there is an extra wire from the switch to ground which as I understand it completes the circuit for the light.
When the main buss is isolated by turning off the master switch all works as expected when I activate the alternative battery feed switch (without the ground wire connected). I now have power to the E buss.
My trouble starts when I hook up the ground wire to the switch for the light. Somehow there is a dead short happening that is burning out this single wire. Nothing else is getting hot, just this one wire. For testing purposes I have put in a temporary wire here with an inline fuse, but I still cannot work out what is going wrong.
I used to think I was reasonably good at figuring out basic wiring, and all the other electrical systems working fine, but I can't help feeling there is something basic that I am missing here. Any ideas anyone?
