Engine Pre-Heat
When the key is turned to the PRE-HEAT position, the KS-105 energizes the pre-heat
signal (connector pin W5) for a 4 second period. If engine connector pin W1 (pre-heat
interval select) is grounded, the pre-heat period is 10 seconds. During pre-heat
operation, the yellow GLOW PLUG lamp illuminates.
Engine Start
When the key is turned to the CRANK position, the KS-105 energizes the crank signal
(connector pin W3), the fuel pull signal (connector pin W6) and the fuel hold signal
(connector pin W7) to initiate the engine crank and start process.
Engine Start Protections
1) Over Crank Protection – Over crank protection is provided by the KS-105.
Cranking is discontinued after holding the key in the CRANK position for 30
seconds.
2) Starter Re-Engage Protection – While the engine is running, the KS-105
disables the crank signal to prevent the starter engagement during
running.
