I am ashamed to admit that I have relied too much on my previous build partner and to this point have not used a tech counselor. I am at the point now where I need to install my panel. I feel lost. I know that I need to run wires and make harnesses but I don't really know how to do that. Is there a tech counselor or perhaps a builder near me that would be willing to help?
To some extent the show must go on. So a few questions:
Do I connect the master switch directly to the battery contactor? And does the other side of the wire connect to a piece of metal, which we can call a buss?
Do the circuit breakers each connect directly to the buss created above and the other wire to the component for the circuit breaker?
I have an IO-390A motor and I will have an electronic engine instrument setup in the EFIS. I will need to run wire to the motor for the instruments. How many wires should I plan to run from the MFD to the motor? Suggested length (longer is better and I will trim later)? Are red and green wires OK to use? I am thinking red for positive and green for negative.
I have decided to go with the Cummins Battery - 31, 950 CCA STUD Battery. I need to build a tray for it, but I am not sure how to determine whether the tray is sturdy enough? Is there some basic formula that I can use to determine how strong to make the tray? The battery weights 82.5 pounds and I am just not sure how to reenforce that weight onto a tray and have the tray be able to withstand the weight. Due to weight and balance I am planning to put the battery under the baggage floor, which is causing me some wiring planning troubles because I need to have a place to run the wire bundles from back to front. What have others done? Should I elevate the battery and run the wire bundle underneath the battery?
I think that this is all I've got for now. I am at a point in my build where I am feeling frustrated and a bit paniced because I feel like I am in over my head. But I have come this far, so I realize I am probably not as in over my head as I feel like I am. However, I do think a tech counselor is needed at this point.
