Re: Battery Wiring Confusion
Note that the above document is dated 1990 and refers to use of YELLOW as a primary power distribution for DC negative. (See page 33). That contradicts the earlier assertion that this standard was implemented in 2007.
Hi jhebert, thanks for finding the ABYC standards.
To help clear up some of the confusion of what I meant by saying the main change was done in I believe 2007.
Though there has been an option of colors to use for ground cables over the years, most but not all of the boat manufactures seemed to choose black over yellow for many years. I can vaguely recall seeing just couple of boats using yellow as a ground cable throughout the years but mostly it was black that was used on basic recreational type boats that I was use to seeing.
When I went to a boat manufacturing plant in 2005 or 6 (been awhile now) I recall them mentioning that they plan on going to yellow soon and I believe the idea was to try and make yellow a new industry standard to start using vs using the black. Most likely this idea was set forth by ABYC due to the dangers of mixing up colors mentioned by UncleWillie.
In 07, The new boats our dealer sold started coming with yellow.
I did not notice where it mentions yellow is the primary color but it does mention Black, or Yellow used for DC negative conductors leaving an option to use either color.
Page 34 was interesting to read for the bilge blowers though. The note mentions if yellow is used for DC negative, the blower must use brown with a yellow stripe.
My apologies for any confusion I may have caused above.
Thanks for the update! Good to hear your getting things squared away.
