    Starting problem

    My 74 cj5 has an intermitent problem. Once in a while it will not start, acts like there is no battery in it, no lights, no horn, no electrical at all. Yesterday i had to push start it then it started right up, ran great, got me home, shut it off, waited a few seconds & cranked right over. I recently installed a new ignition switch, had the battery checked out, its good, checked & replaced all fuses, it only does this once in a while. Any thoughts, this is a 304 with t18 trans. Thanks.

    Have you load tested the battery?
    Cleaned battery connections and opposite end connection? Like the engine and chassis ground connections.

    Does your alternator have serviceable brushes? I had a 95 f150 that wouldn’t start randomly. I noticed the battery voltage fluctuating on last drive before no start. Changed brushes and no more issue.

    I keep my battery connections clean religiously so I dont think thats an issue, could there be a ground connection loose somewhere I dont know about ?
    I dont think my alternator brushes are serviceable, it does put out 14.5 volts constantly. Could my starter solenoid be going, it is the fender mounted "ford" type.

    Starting problem

    You mention no lights, no horn that means no power. Has nothing to do with the starter solenoid.

    Did you clean the other ends? Ground to engine. Ground to chassis.

    Cables could be corroded. You could ohm one side to the other. Or you could ohm the ground cable to some body or engine part. It should be less than 5 ohms. More like 1ohm
    What if you take a jumper cable to create a new ground to engine and power to the starter.

    Ground cable from battery to alternator bracket/engine reads .3 ohms

    That is good.
    I measured 25 ohms once when i noted the headlights pulsing.
    Replaced and cleaned contact points.
