Can anybody help with this.
I have a genuine C12 new wiring harness. The colour codes for the wiring to the alternator as per c12 wiring diagram are DARK GREEN/ LIGHT GREEN AND PURPLE.
However my alternator output wiring colours match the alternator for a C15 and are GREEN/black stripe. GREEN/yellow stripe and WHITE/with a green strip.
Can anyone assist with connecting the alternator wires fitted to the correct wiring harness colours.
Thanks in advance
On the "C15" wiring ... White / Green is "common" ... Green/Black is "Charging" and Green/Yellow is "Boost" (when lights on)
For the C12 wiring ... Light Green is "Common" .... Dark Green is "charging" and "purple" (or should that be Mid green or green/yellow ... depending when RM13 was made) is "boost" .... On service sheet 808D, for C12, "purple" is the -ve output of the rectifier. Picture from 1966 Lucas manual attached.
The "Common" and "charging" go to the rectifier and "boost" to the switch (so it connects when the lights are on).
