(I know I can be very stupid at times!!!! ) | Dear Abhishek / Karthik / Ilangop - if I have to reply to you in totality, it will take me around 3 hours to type everything. There is a huge amount of information to be shared. If I find time tonight, I will type and send. In the meantime, as you have clearly mentioned that the engine switches off just at the point when you leave the key, you mean to say that engine fires and runs when the starter motor is operating but as soon as you release the key from its spring loaded "starter actuate" position, then the engine dies. IS THIS CORRECT? If yes, the solution is extremely simple. The ignition switch has two wires going to the ignition coil. One wire goes to the input of the ballast resistor (bottom connector). The ballast resistor is the part which is attached to the body of the ignition coil. It allows you to use a 6 volts coil in a 12 volts system. The intention is to facilitate starting even if the battery voltage falls below 12 volts. However (now read carefully), during the "starter actuation" phase, means when the key is in the "spring loaded / holding" position, there is another wire which connects directly to the ignition coil's input terminal. This is the "+" terminal on the coil. If I remember correctly, the bottom wire was specified as black or dark blue and the top wire was specified bright yellow. The bottom wire has a slip-on Lucar connector whereas the top wire has a round connector. The intention of the top wire is to feed 12 volts directly to the 6 volts coil during cranking in order to shunt the ballast resistor out of the circuit during the cranking phase. This helps in starting. Correction is simple. Connect a wire from battery positive to the ignition coil "+" and then crank the engine. If it continues to run after the starter motor is outb of the circuit, the "bottom" wire which feeds the coil all the time is not getting current. Solution - CHANGE THE IGNITION SWITCH. Aword of caution - PLEASE ANALYSE LIKE A PRODUCT ENGINEER BEFORE YOU SPEND YOUR HARD EARNED MONEY ON CHANGING PARTS. The ignition switch is of JAY make, costs around 700 rupees and is extremely unreliable. If I were you, I would just have a wire with a simple 4 rupees ON / OFF switch on the dashboard, feeding the coil. To start, just pull the switch out, to stop, just disconnect. It is better than spending 700 bucks on something which I am telling you is unreliable, so be careful. Also, when you write on the forum, give clear inputs on symptoms / observations so that I can guide you properly. Most of your comments areextremely vague.
I am posting the picture of Jay Mehta's Himalayan Rally prepared 118NE GBO409. This car was prepared in England and had WEber carburettors / brake bias system fitted. You will observe that the rear bumper is fitted incorrectly. We pointed it out to the competitors but as the supplementary regulations did not specify anything on it, we allowed the car. I had taken this picture in 1989 at pre-event scrutiny. I was one of the scrutineers for that event. That's me on the extreme right in the second picture. I do not know the names of others. The car was extremely fast, one day before the event, Asif Hyderi who had gone to England with the car and I did 140 kmph on the Delhi Ghaziabad highway. In those days there were no double roads. It did not complete due to rear axle issue. Dear Ram - the grey car looks good. Have you picked it up?
