Ferrari Mailing List: Re: Oil temperature gauge not working (1981 308 GTSi)

[Doug & Terri (dnt]

Ferrari electrics chose BLACK as a GROUND.  Why? Dunno

True enough, the oil temp sender wire is BROWN. 

Thanks for the clarification Paul.

Solid RED is unswitched and may be unfused HOT while red with some sort of tattle tale coloring is a hot wire hooked to a switch someplace.

 

Bosch chose green for oil temp sender and brown as ground.

 

There is a fellow who made colored wire PDF (?) which is sensational.  No Ferrari computer should be without it.  Address - - - ?

Wait a minute -  - that fellow IS pbennett [at] Paul-Bennett.com

 

Onward

Doug

 

PS – Paul: my version of the clock wiring shows no hot wires to it . . . all lines are black.  Great addition to my library.  Thanks again

I thought everyone had the colored wiring diagrams ... the oil temp sender wire is BROWN
