This happens usually when the car has been driven for 1-2 hours, and then if for some reason I try to restart it - it will not crank. Sometimes when I wait for 10 minutes - it cranks and starts. Sometimes it cranks with slight delay - approx. 1 sec after turning key in crank position. What could it be - except bad starter? One more thing I noticed - the voltage drops slightly - from 12.6v to 11.6 volts but no audible sound nor sth else noticable happens.
Otherwise the car runs ok and no weird electric things happen.
Best regards and thanks in advance.
PS: The car is 1993 ford escort 1.6 16v 90ps.
