startproblem 500SL
 

Hey there,
I got a startproblem with my car 500 SL from 1991.
When I start my car, then the controllights on the dashboard doesn't light up en the car don't start. The startmotor turns normally and powerfull. After sevreral attempts the controllights functions normal en the motor start also normal.This happens most of the time when the motor is hot or warm.
Also I have seen, while I drive the car, all the controllights flahshes for a moment, the cruisecontrol is then disconnected, but the car drives normally.
This last malfunction happens very rare.
I hope that anyone can help me to resolve this problem.
Thanks in advance,
Bullet.
