hi
I/m not sure I posted in the right part of the forum but let's try. I have sun gas analiser and some time ago it started developing intermitent fault HC indication - was flicking from value to ---- . Snap on engineer looked at it and suggested new mother board which is similar money to new unit .Because we are not doing mots I don't bother to get this replaced or fixed for big money. Maybe someone of you guys would have specialist who could look into it at give proper diagnose. many thanks
