First get a test light & make shure the large red wire at the back of the alt. is hot all the time. The connector should have 2 terms. parallel to each other. II. Remove the connector from the regulator. On term should be hot all the time. Another term should come on when you turn on the ign. switch but may not be as bright. Connect a jumper from the hot term to the blue term. You should get a little blue spark when you make & break the connection. Start the engine. The alt. should charge infinitly. If it doesn,t it is defective. If it does & the other tests are good the regulator is defective.
