First a bit of back story: After casually drilling holes under the dashboard in my 1973 (type 4 motor) I let out quite a lot of smoke and caused alternator light to shine. I turned off battery, let the smoke die down and fixed the loom near the hazard warning switch - there was a fairly fat red wire (permanent 12v) and a thin blue wire (alternator light). Now the alternator light doesn’t shine In addition the right indicator stalk doesn’t work - I do not know if this is connected or a red herring. So far I’ve established bulb is fine - it has 12v with ignition on and if I ground the bulb it lights up. The alternator works just fine with 14v at battery when engine is running (I thought it needed to alternator light to ‘activate’ the alternator). I’ve tried a new voltage regulator with no change. As I say, the right indicator light doesn’t work, but left indicator work and light up both lights on dash. The hazards work just fine, as do the headlights. All fuses look fine. I can’t find the blue wire in the engine bay. What have I broken and how do I fix it? Do I even need the alternator light if it seems to be working fine (although I do really want to sort it). Thanks in advance!
