Circuit/System Testing

1. Disconnect S2.
2. Probe the 12 volt reference circuit with a test lamp connected to ground. The test lamp should illuminate.

⇒	If the test lamp does not illuminate, test for an open or short to ground.

⇒	If circuit OK, replace FTC module.

3. Probe the signal circuit with a test lamp connected to B+. The test lamp should illuminate.

⇒	If the test lamp does not illuminate, test for an open or short to voltage.

⇒	If circuit tests OK, replace FTC Module.

4. Test the signal circuit for a short to voltage. Repair as necessary.

⇒	If no short to voltage is found, replace S2.
