The car fails to start when the engine is hot (TVR's)
The M36 immobiliser:
The M36T2 immobiliser is a two circuit Thatcham approved immobiliser, it is manufactured with very high quality components to a very high standard & as such this is one of the most reliable immobilisers manufactured today, many of these systems are still working perfectly on vehicles which are well over 15 years age.
Problems arise because TVR have wired the immobiliser circuits the wrong way around. The M36 has two immobiliser circuits, circuit 1 can handle currents of up to 10 Amps & should be wired to the fuel pump or ignition circuit, circuit 2 is rated at 25 Amps & is designed to be connected to the starter motor circuit. TVR have wired these circuits the wrong way round, the starter goes through the 10 amp while the fuel/ignition goes through the 25 amp circuit. All being well there are no problems even though the two relays are wired the wrong way around. Problems arise when the starter solenoid begins to wear, in so doing it demands more & more power to function, when the current flow to the starter gets passed the 10 Amp limit of circuit 1 problems start. This situation gets worse when when the engine is hot which in turn makes the starter solenoid hot causing it to demand more power. This is known as the hot start problem, eventually the starter circuit will burn out causing total failure of the starter. Adding an extra 'hot start' relay to this circuit is not a permanent fix as the starter will still demand more power which could eventually burn out the ignition switch or associated wiring leading to the failure of the starter itself. Before this happens we recommend to have the starter inspected & have it repaired or replaced if found faulty.
All replacement TVR adapted M36T2 immobilisers will now be sent out with the immobiliser circuits switched to match the TVR wiring, this will now match the higher rated relay to the starter circuit of the TVR, this should cut down on the hot start issue
