Electrical problem
1977 Questions for all other cars V8

Whilst trying to jump start my Triumph Stag, I stupidly connected the wrong leads to the terminals of the donor battery. Now the ignition light stays on of the Stag even when the key is removed and the indicators don't work. Hazard lights, headlights, windscreen wipers, electric windows etc still work. It has an electronic ignition fitted.
Please can you identify what I've damaged apart from my pride !
Thank You, Helen
