[TR] TR4 wiring ignition

[Gary O'Hagan]

OK , I thought I could figure this out but I should have known better.  
How hard can it be ?  I have the wiring diagram. Just plug in the wires 
, right?
The problem with connecting" the" Brown/blue wire to the no. 1 terminal 
is that there are three brown/blue wires to choose from. Which two 
attach to the ignition and where does the third brown/blue wire go?
The  wiring diagram I have shows one brown/blue wire coming from the 
lighting switch and one coming from the generator control box. Where 
does the third brown/blue wire come from and what does it connect to? 
I'm going to have to trace all these wires aren't I? And I'm just 
getting started here.  Yikes!  Also how do you know when a good voltage 
stabilizer goes bad? TIA again.
