The ECU has seals around it which are supposed to prevent moisture from entering inside. Its important to keep the motor cool during its normal operation. Typically, the starter solenoid goes out causing this problem, but the starter will Be sure any engine immobilizer system (security system) is not activated, thus preventing the car from starting. It is not surprising that the windings of electric motors are essential for their mechanical functions. I use thermal imaging camera to detect motor temperature rise. Starter burnout can be caused by overloading, excessive cranking, worn brushes, dirty or corroded connections, loose connections, a faulty solenoid, and poor maintenance. This temperature rise causes winding insulation breakdown, the insulation breakdown causes a short circuit that burns the electric motor if the protection device fail to operate. because it will continue to draw on the assembly. Burnt-out Another common fault is for the armature to burn out. Next, inspect the electrical connections between the battery and the starter motor for any signs of corrosion or damage.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'carcarehacks_com-large-leaderboard-2','ezslot_9',128,'0','0'])};__ez_fad_position('div-gpt-ad-carcarehacks_com-large-leaderboard-2-0'); If the cables are loose, it could be preventing enough power from reaching the starter motor.
