Re: Wiring schematic app?

L124C Can you send your wiring spread sheet. I am learning a lot from this thread and your number system will put it all together. Thanks.

Don't know how to transfer the spread sheet file, so I copied the text below. Nothing special. Just the wire number and description of the it's function. Missing numbers (i.e., 1-9) haven't been assigned yet. Wires are numbered with the adhesive wiring stickers you can get at Lowes.

Not even sure the spreadsheet is the best way to do it. You could use a numbered text document just as well, or make a little data base if you really wanted to get fancy! The advantage to having the diagram and list in digital form is that you can edit them as you make changes, and print new copies to have on the boat. I'll look at the diagram and go to the list if I need clarification. Should eliminate those, "how (where) the hell did I run that wire??" moments!

The diagram also points out weaknesses. For example I'm thinking I should run the ground in 34 from the Starboard mid ship box directly to the batteries instead of having it run all the way back to the ground at the switch panel, where it goes forward again to the batteries. Probably eliminates about 30 feet out of the circuit. This wasn't really an option until I installed the Starboard midship junction box. In any case, it wasn't apparent to me until I looked at the diagram.

10 +/- Nav lights from panel to aft nav light bus.
11 +/- Stern running lights
12 + Bow running lights
13 +/- Port bow running light
14 +/- Starboard bow running light
15 + Tri color masthead light
16 + Steaming light
17 + Spreader lights
18 + Anchor light
19 - Steaming light Returns to panel via 23 & 30
20 - Spreader lights Returns to panel via 23 & 30
21 - Tri color & Anchor masthead light Returns to panel via 23 & 30

23 - Returns 19,20,21 to Port midship box, then to switch panel via 30

25 Wind instrument (Instrument to masthead)
26 Depth instrument
27 Speed instrument
28 Battery Monitor Shunt connects positives from both batteries to monitor and motor ground to batteries.

30 +/- Port cabin lights to mid ship (connected to 34) . Connected to 34 at switch in panel.
31 +/- Light above stove

34 +/- Starboard cabin lights. Panel to mid ship bus box. (connected to 30)
35 +/- Halogen light on port bulkhead in saloon

37 +/- Light above stereo

39 +/- Florescent light on starboard bulkhead
40 +/- Light above sink
41 - Bow lights. Returns to panel via 34
45 +/- 12V charge terminal above AM/FM (fuse at terminal?). Pos. also supplies back up AM/FM power (Fuse in radio). Source - forward bus at batteries.
