Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Do you have access to a test light or a volt meter. Have you tried swapping the relay with another?
Relays number 11 and 12 are crank and ignition main relays. Try switching them with 9 and 10 (cooling fans) and see if there is any change in symptoms.
Alright. Let me know what you come up with!
Jumping the crank relay will engage the starter if the trigger wire to it (the small one) is good and the starter is good. If you jump the relay and the starter does not engage then we need to see if power is getting to the starter on the small wire. It should have 12 volts at all times on the bigger cable. Let me know how it goes!
