N40469 Chapter 3 Circuit breakers Cautions: • Always fit the correct breaker. Damage to the wiring loom may occur if a higher rated breaker is fitted. • Always find the cause of a breaker failure and correct the fault. If in doubt, consult an electrician at your nearest Perkins distributor. A wiring loom, which includes a breaker panel to protect the wiring from damage by a short circuit, has been fitted to your engine. The breaker panel is below the exhaust manifold and above the oil filter and has the following breakers: • 10Amp - start Figure 8 • 105Amp - glow plugs Should a breaker trip, it will stand proud of the panel and it can be reset by pushing it in. Warning!
Ensure the electrical system is isolated before performing any electrical work on the engine. If a breaker needs to be replaced, realease the two retaining screws and remove the wires. Insert the new breaker by attaching the wires and re- attaching with the retaining screws. Page 17
