Komatsu/Nikko starter relay switch

Most komatsu construction equipments uses a safety relay switch or IMS. Its function is to keep the operator from engaging the starter if the engine is running. It gets its signal from the alternator. If the engine is running and the alternator is charging, the starter motor is not allowed to engage.
The starting issue appears to be a result of a safety circuit that prevents the starter from being engaged when the motor is running. This is to prevent starter motor and flywheel damage in the event driver tries to start the motor while it is already running. There is a diode in the alternator that prevents the starter relay from energizing when the alternator is making charge, i.e. motor is running. When the diode goes bad, the starter relay is deactivated and the battery relay is kept from energized.
However Komatsu changed the circuit in the newer machines and instead has a diode under the seat that provides start circuit protection in many of the smaller machines.
Look at you alternator to see how many wires there are. The older machines will have three wires, the big battery terminal, a small black wire for ground and another wire for that works the safety relay on the starter. If you have only the battery and ground wires you will have to look for the diode. Last machine I worked on was a couple of years ago so I don’t remember exactly where it was but I do recall having to pull the seat to find it.
The issue with the battery relay not dropping out is probably something different. Have you installed another electrical component? Radios and heaters can be a big problem. Have you recently had a component failure like a wiring harness or maybe a fire? The reason I ask is that your relay works on the ground side of the circuit. When you turn the key on it only provides a ground that lets current flow through the coil. A short circuit in any component or the wiring harness will keep the battery relay engaged. You might try pulling fuses and keeping track of what they supply. When the relay drops you might have found your problem.
