Goodmorning friends!
I have a request for some education. First let me explain an embarassing event yesterday...I had hooked the battery leads up inreverse!! There I said it! Why? Not paying attention. I have the battery on a cart next to firewall battery tray and I have the ground wire off firewall hanging free for ground hook up and the pos lead attached to master relay. I simply use two leads with aligator clips to quicky connect the battery and then work on Dynon set up etc. After many times of hooking in, I reversed by mistake and the wire from master switch to master relay burned up! Very scary and I dont ever want to smell or see that again!! I have since removed that wire completely as well as the ground wire from switch. I untied all wires in the bundle and inspected each for any breaks in tefzel coating or signs of melting. and reinstall new wiresing as required.
I plan to buy a new master relay and master switch and diode just for good measure.
Question-how does the master relay function? Im confused as to why the small wire from center stud on master relay is the one that burned up. I guess it fused and shorted the ground wire from the master switch as well.
Im replacing the relay because I have no idea if its damaged or not. Is there a way to check?
Ive pretty much decided to replace just for peace of mind but I am looking for instruction and commects and advice. Thanks in advance!
BTW, this almost made me quit as I dont know much about wiring but Im trying to fix and push on. After puitting new wires, I tested the function of radios and such by hooking into main buss (carefully) and bypassing the relay. This verified that radios and panel items ok. No smoke either.
Thanks!
