Basic wire color guidelines
Basic wire color guidelines
(OP)
Is there such a thing as a "basic automotive wiring color standard"?
I have designed and built an electrical system for a large piece of turf-maintenance equipment that is now in production. Now I need to go back and make changes, and I would like to make it as easy as possible for a service tech to work on later.

Most of the stuff I work on seems to use Black, red, Black with a red stripe and red with a black stripe.

Or maybe I'll write my own standard....(oh yeah...the electronic world needs MY help)

I have worked on countless brands of machines and reviewed manuals from many others. CaseIH and Hyster/Yale use a type of ladder layout that works good for understanding the particular circuit and keeps all the circuit components on one page, but doesn't show where the component is in the vehicle. (grounds run along the bottom of the page, supplies on the top) Most use a compressed line drawing that spills over multiple pages that is hard to follow - till I get out my markers
One story - I spend one whole day trying figure out why a track loader would not move. It was obviously something wrong with the safety interlock and I suspected a relay. There were 3 different versions of the wiring circuit depending on VIN#, and none of them matched so I had to trace the wires with my DMM. And to make matters worse they hid the damn relay under a bolt on kick panel but didn't show it in the manual! Not happy. Should have been a 20 minute job that my technician could have figured out.
