As usual i think that Dick is right ! My engine is set with more advance than factory (10 - 12 ° advance) and someone told me that it's perhaps why i has some troubles to crank the (hot) engine. i'll test the draw current (at cold and hot starter). The FSM says that current should not exceed 150 A with warm engine and battery (problem is to find the right amperemeter.. or to use a "amperemeter plier", don't know the right word !) and that the voltage between + post of battery and + of starter should not exceed 0.20 v per 100 A of current. If this voltage exceeds 0.20 v / 100 A: high resistance (loose connections; burned switch contacts) High current (> 150 A) + slow cranking speed = starter should be removed and repaired .. Low current + slow cranking speed = resistance in solenoid switch , loose brush or soldered lead starter (worn brushes or burned commutator) -- Philippe COURANT (Pau, France) Imperial 57 Crown convertible Buick 58 Roadmaster sedan - American Car Club de France (ACCF) : http://www.accf.com - Chrysler Imperial France : http://www.ifrance.com/c-i-f - Cadillac " Standard of Excellence " : http://www.ifrance.com/accf-cad - SportsCars : http://www.ifrance.com/accf-sprtcar
