Reported Issue: Remote starts fine but only runs for only approx. 10 seconds then shuts down:
Situation: New Install w/o Tachometer Connection
Specific Vehicle, System, or Bypass Interface: General troubleshooting
Possible Cause: System programmed for "Voltage Detection" Setting with Voltage detection level set to high:
Possible Fix: Program system for less than 1/2 Volt detection (<0.5)
Reason for the adjustment: The system is not detecting the vehicle's alternator kicking in after remote start/crank. The system needs to detect at least 1/2 a volt raise in the voltage levels on the interior side of the vehicle's wiring; the wires to the remote starter wires are directly connected. After start, the system waits to detect the voltage to raise and if no raise over 0.5V is detected within a short time the system will shut down assuming the vehicle did not start or stalled (many system models will automatically try to restart the vehicle again on its own).
Recommended Fix: Hard-wire the system's tachometer input wire to the vehicle's tachometer wire and program tach signal to the system. Using any system's tachometer input option is the best way to go 98% of the time.
