I am facing serious problem with my conversion switch. In my mehran (Model: 1998) i had installed touch type switch a month or two ago. Mostly i run my car on CNG (the yellow light on the switch is on), While driving 10 to 15 km on CNG, both lights (orange for petrol & yellow for CNG) of conversion switch gets ON, causes fuel mix and car stops. I have visited two electricians and they both said that wiring and switch is ok but problem still remains.
Kindly share your suggestions about the problems as you can imagine that how critical it is when you are driving in fast lane and your can went stop suddenly.
