2 to 3 clicks when cold starting.

    Recommended Posts

    I am noticing that everytime i try to crank the engine on my 72 240z when is cold i hear 2 to 3 clicks. I do open the choke to 3/4 but somehow i can still listen to those clicks failing to crank the engine. Battery was bought 6 months ago but i normally crank the car once a week every sunday. Starter may be failing? Once the engine cranks and i shut it when i crank again there is no more clicks as it starts up right away. Where do i check? I didnt had these problem before.

    Starter solenoid may be going bad. They can go bad even when they sit

     No need to go any farther than your local auto parts store. Measure each flexible hose you want to replace. Add the lengths and round up to the next foot. Cut the new hose to fit and replace any suspect clamps with new ones.

    Thanks Pat. How can i double check this to be sure its not another part.

    I also noticed that the tone of the horn is low when the car engine is shut

    New batteries can and do fail.  I would check the battery voltage first.  You can find battery charge/voltage charts on the web.  Low horn would/could be another indicator of a low battery .  After running and shut down the battery would have been charged some and the engine is warm.

    The most common problem that I've seen is dirty/corroded battery connections.  Clean them up and try again before buying anything.

    thanks! Just some cleaning with brass brush and battery terminal wire and everything was solved.

    3 click issue showed up again and now when the engine was fully warmed. Solenoid replacement? Any good brand?

    After cleaning the battery poles put some special grease for that on them..

    Solenoid can be a bad contact, clean it.. after you have taken it apart you'll see if you have to get a new one and what kind. succes!

    Check battery voltage for completeness.  It should be ~ 12.6V in the morning before starting the car and ~ 13.5 to 14.5V at idle.

    Battery voltage before crack and after crank at idle

    It looks like your battery is not charging.  The 13.9V is a healthy charging voltage so this means your alternator is working correctly.

     

    The 12.1 V after the battery has rested means it is weak.  It should be 12.6V to 12.8V.  Please repeat the test tomorrow morning and take a few measurements while "digging-in" the probe tips from the voltmeter to see if the voltage really is 12.1V on a rested battery.

    Could still be dirty/corroded terminals.  Or loose terminals.  Many people just push the terminals on to the battery posts by hand and leave them that way.  They have to be cleaned then clamped down tightly on the posts for the cleaning to last.  Otherwise they just get corroded again.
