CAR DIES

1996 SAAB 9000

Electrical problem
1996 Saab 9000 4 cyl Front Wheel Drive Automatic 176000 miles

My 9000 Sc 2.3L has daylight running lights on but will die when Head light switch turned on. Will not restart even when you have it jump started with another runing car untill randomely after some times or days will restart but will repeat the same if you turn the switch on. Alternater puts out 14.19V. Grounds checked and H/light relay changed. Connections secured all other relays checked seem to be ok. During no start time instraument lights are out too. What can be done to remidy this problem.

Other than shorting out the ignition switch, Im not sure where the headlights could shut down the car like that. Have you tried pulling the light relays (h-light, fog light, DRL) to see if it still does it?If noit, install them one at a time until it kills the car again, this will at least tell which system it is
