    ?

    One of my older cars sometimes acts like the car battery is dead. Occasionally I turn the key and I hear 1 click. If I turn the key rapidly 6 or 7 times it starts. Lights and dummy lights look strong... old battery was doing the same ( I just replaced w/ new batt)

    Mechanic's are useless so far.. I understand. They say. if it starts when we do it we can't be certain of the cause.. Thoughts???

    Make sure your battery wires are snugged tight, check both ends. Alternator possibly going bad. Could be your starter has a bad spot. Im no mechanic so dont listen to me....

    yeah, pretty much the chain to inspect:

    battery/cables
    starter
    solenoid
    voltage regulator
    alternator

    How old a car? The one thing that voids out everything is the computer. A computer can cause that as well.

    what is year and model ?? i can give an ignition /key knowledge on that being an Auto Locksmith, you have the correct signal path up above posted to start diagnosing..just curious if you have a model with a known ignition switch issue

    What car is it?

    Battery cables: the connectors on the battery terminals, the terminals that connect to the starter can corrode.
    The starter relay can wear out.

    And you are correct:
    most mechanics don't know shit about troubleshooting electrical. Most of them are total idiots when it comes to electricity.
    They guess, they replace parts randomly, and charge you up the ass.
    Most of them could not use a volt meter, ohm meter or current meter, they haven't got even a clue how to use test equipment.
    Most of these guys could not pass electrical 101.

    Its a 2006 Saturn Vue. I have a new alternator and battery. Brand new. I just know from life experience.. probably Starter.. but mechanics were unsure of anything and I am not a young musician.. lol. I can pay! I have a 2019 I bought a couple of months back but I don't want to drive it to work because I am in a Sanitation garage. All kinds of bumps and bruises happen every other day to my other cars

    The lights are all bright as hell so that makes my non mechanically inclined mind think the alternator is charging the batt.

    More than likely the starter. What vehicle and year ?
    If it were the battery a new one should have fixed it . Old starters get worn out and the bendix will no longer function
    ingaging the pinion gear. The old trick was to bang on the side of starter to get it to go. Not a fix just a temporary thing.

    If in fact the alternator is bad it will not charge the battery. Easy check with a ohm meter. Check voltage before you start. Should be a bit above 12 V running around 14.8 V with the lights on.

    If the battery was always low or the starter is bad the worst thing is it could wear out a spot on the ring gear. (Not a easy fix)

    New alternator and battery pretty much eliminate the alternator and battery. The strong light reinforce that, although, lights don't take as much juice as pushing that motor over. I have seen weak batteries that light up the lights just fine but don't spin the starter.

    I am thinking starter or switch, but I would still clean up the battery terminals before doing anything else. That is easy and costs nothing. If you still have the problem then I would look at the switch next. Go from easiest to hardest and hope it's something easy. A little contact cleaner sprayed into the switch might be all it needs. I guess around here I better recommend Deoxit. :)

    Probably the starter relay, or the connections to the starter are corroded.

    Given what you said if it aint the battery it is most likely the starter. If your clicken the battery and relay aint sticken. Ah, I do not know anything.

    Although, I have not had a starter go bad since my 1978 Ford. But :shrug:.

    The starter (could) contain a solenoid and when the solenoid contacts fry out, the power does not reach the motor.

    Key switch> starter relay> Solenoid> motor

    as bft said up above, it could also be an ignition thing...

    yea, start from the switch, relay, and work back to the solenoid/motor assembly. luckily none of these things are expensive.

    If it clicked it tells me that ignition is ok. Cant say for the ECU but I'd say it's fine.

    Like everyone has said check connections including at starter.

    My guess is the solenoid isn't moving the armature far enough to engage the contacts. If it happens and there is another person around try tapping the starter with a hammer. That's if you can. As the starter is being tapped hold ignition in star position. If car starts then replace starter and you should be fine.
    Good luck

    Solenoid/Bendix …… smack it with a wrench …… see if it spins out
