Why SMPE Rotating Electrics?
SMPE offer a range of surcharge free starter motors and alternators which are factory tested and come with a 12 month warranty. There is currently over 85% vehicle coverage on the range.
What They Do
Starter Motors - A high torque electric motor used to spin the engine at a speed fast enough to start it. The solenoid that is mounted on the side of the unit acts as a high current switch that engages and activates the motor upon driver demand.
Alternators - An engine driven unit that maintains the batteries state of charge. Modern units incorporate a regulating pack that limits that output of the unit to prevent overcharging at high RPMâ€™s.
Alternators fitted to diesel engines often drive the brake servo, which may or may not be part of the assembly.
Starter Motors - Engine not starting.
Clicking noise from under bonnet when attempting to start.
Burning smell when starting.
Rattle/noise when starting.
Alternators- Sluggish starting when cold.
Headlights dimming at night.
Burning smell from the alternator.
Egg/sulphur smell from the battery.
Battery fluid level drops
Starter Motors -Although no maintenance is generally required it is good practice to check the electrical connection and security of the fixings. Starter motors use a ring gear affixed to the flywheel to turn the engine, it is good practice to inspect this at any time access is available, ie renewing the clutch.
Alternators - Careful and regular attention should be made to the drive belt condition and tension; many charging faults can be attributed to belt slip. It is recommended that a new drive belt be fitted when the alternator is renewed.
Due to the high output of modern alternators the electrical connections are highly stressed, repair/renew any that become a problem.
When servicing units that incorporate a brake servo unit, ensure that any relevant seals are renewed.
SMPE's starter motors and alternators are available in the Fuel Parts brands.
