Power Supply Tests:

1.Take all measurements at ECU harness connector.

2.Place a load (e.g. an 1157 stop lamp) across battery or ignition and ground connection, measure ignition and battery voltage with the load. Ignition to Ground should measure between 9 to 17 VDC. Battery to Ground should also measure between 9 to 17 VDC.

3.Check for damaged wiring, damaged or corroded connectors and connections.

4.Check condition of vehicle battery and associated components, ground connection good and tight.

5.Check alternator output for excessive noise.
