- If the solenoid clicks while trying to crank the engine with the starter, which of the following is not a probable cause? A faulty neutral safety switch Low battery voltage Low voltage available to the solenoid An open in the hold-in windingarrow_forwardWhen diagnosing a no-crank no-start condition, no voltage is present at the S terminal of the solenoid while attempting to crank the engine. Technician A says a faulty starter motor is the cause. Technician B says a shorted safety switch is the cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardAn engine cranks slowly: Technician A says that a possible cause of the problem is poor starter circuit connections. Technician B says that an engine problem could be the cause. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Cranking current is excessive but is normal when the starter is bench tested: Technician A says the problem could be with the positive battery connection to the solenoid. Technician B says there could be an engine mechanical problem. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhile discussing a no-crank condition: Technician A says to verify the condition of the batten' before testing the starter motor Technician B says a scan tool may be used to check starter control circuit operation. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says that a starter no-load test is conducted with the starter in a bench vise. Technician B says that the no-load test is used to determine starter motor circuit voltage drop. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Technician A checks a starters field coils for opens by connecting an ohmmeter between the coils' power feed wire and the field coil brush lead. Technician B checks a starters field coil for a short to ground by connecting an ohmmeter across the field coil brush lead and the starter housing. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTrue or False? To eliminate the drain of engine power during times when cooling fan operation is not needed, many of todays belt-driven fans have a fan clutch that prevents the operation of the fan when the engine and radiator are heated up.arrow_forwardIn El systems using one ignition coil for every two cylinders: Technician A says that two plugs fire at the same time with the same voltage used by each spark plug. Technician B says that one plug fires in the normal direction (center to side electrode) and the other in reversed polarity (side to center). Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forward
