Whirring noise coming from?? What is battery voltage, Has to be above 12.5 volts. If you jump the two cable terminals on the solenoid, will engine spin??
Jumping the solenoid is quick check of the battery, cables and starter. What did the test you performed show?
What is battery voltage when you get whirring?
You don't have the exact reading? Use higher scale than 10V
If jumping the solenoid does make engine spin, you have bad battery, cables or starter.
What is battery voltage when you hit start?
Battery has to have over 8 volts when the starter is engaged, or it will not spin like t should. ?? I assume this is not a digital voltmeter.
It takes a lot more amperage for start, than for lights!
OK> Let me know!
