Re: Car Stalls When Put in Gear

Unusual problem, there is no direct link between engaging the transmission and either the fuel delivery or ignition system. Perhaps too low an idle speed or a large vacuum leak? You didn't say but I'm assuming the car has power brakes - check the vacuum lines to the brake booster and vacuum reserve tank for good leak-free connections. There are other possible sources for a vacuum leak and they should be sought out and checked but I doubt any of them have the potential to stall the car when the transmission is engaged.

There are several ways to analyze your charging system. A relatively easy one only requires a voltmeter attached to the battery. Read the voltage at rest (engine off), should be about 6.4 volts. Start the car, leave it idle and put on the headlights, read the voltage; then increase the engine speed and the voltage should increase to perhaps 7.3 - 7.4 volts. If it does not increase then the charging system is not functioning. Now just briefly connect a wire from the field terminal (F) on the generator or regulator to ground and repeat the test - if the voltage now does increase the generator is functioning and the problem is with the generator regulator (replacements readily available). If the voltage does not increase, the problem is with the generator itself. Do NOT leave the jumper wire between F and ground connected for any longer than needed to conduct the test!
