Lucas 15 AC alternator r

Recommended Posts

I have a Lucas 15ac alternator with a external regulator, and intend replacing with a 18ARC with an internal regulator.

Car has been rewired with a RHD TR5 wire loom.

Is there a wiring drawing showing the modification required to the wiring

Hi John,

I have a 18ACR Alternator on my 5 and I only have two wires connected to it, The thick Brown and White and the Thin Brown and Yellow,

The Thin Brown and Green is not used, I'm sure someone with more knowledge of electrics will be along soon. Hope this help's,
