- To check power transistor for cylinders No. 1 and 4, connect analog ohmmeter leads between power transistor terminals No. 3 and 8. Perform TEST 1. See Fig 1 . Using a 1.5-volt dry cell battery, connect negative lead to terminal No. 3.
- Touch positive battery lead to power transistor terminal No. 7. Observe ohmmeter. Continuity should exist with battery connected. No continuity should exist with battery disconnected.
- To check power transistor for cylinders No. 2 and 3, connect ohmmeter between power transistor terminals No. 1 and 3. Perform TEST 2. See Fig 1 . Using a 1.5-volt dry cell battery, connect negative lead to terminal No. 3.
- Touch positive battery lead to power transistor terminal No. 2. Observe ohmmeter. Continuity should exist with battery connected. No continuity should exist with battery disconnected. If transistor(s) does not test as specified, replace power transistor(s).
