Lately the first time I turn the key, the engine will not turn over (no noise, clock goes off during start attempt, but interior lights do NOT dim if on). Usually it cranks on 2nd attempt, but last night I had to turn the key quite a few times before the engine cranked.
Original starter (loping crank with dead spot) was replaced a few years ago. 2nd battery from 1999 (5v cranking) was just replaced last Thursday (cleaned battery connectors with wire terminal brush). Neutral switch was replaced earlier this year when backup lights did not work (they work now).
Any idea if intermittant no crank could be due to ignition switch, clutch switch, starter solenoid, or corroded wiring somewhere other than at the battery?
