About this course

Learn to service and repair the small petrol generators that keep Nigerian homes and shops running — oil changes, filters, spark plugs, carburettor cleaning, and diagnosing the faults that bring a gen to your bench. You'll also learn to run a maintenance-service business that turns one breakdown into a regular client who calls you for every service, every fault, and every neighbour's gen too.

When NEPA takes light and the whole street coughs to life, you are hearing demand. Every one of those gens will eventually break — and the person who knows how to fix it never lacks work.
