    Hi,
    Is my starter motor on it's way out?
    After a day stood the motor won't spin, the solenoid clicks,the battery is good
    the terminals and wiring look ok.
    I have tried rocking in gear but no joy, after persevering it starts
    Once it spins and fires it works fine for the rest day
    Any info would be appreciated.
    Thanks Joe

    Might be a dodgy connector in the wiring loom, could be the solenoid too. For a test to find out which it is. Take a piece of wire connect to Batt + and touch it to the small spade connector on the starter solenoid. This bypasses the loom and will spin starter w/o key on. If your key is on it will start & go.

    Sounds like the standard Startus Interruptus problem. Yes it did apply to models in the 80s too.
    Had to do the mod on my V50.

    Easiest way to check the starter is to take a large screwdriver and bridge or short between the top big terminal on the solenoid to the spade terminal. It will spark a bit, but should immediately pull the solenoid in and spin the motor. If it doesn't, short between the two big terminals on the solenoid. This should just spin the starter motor, but not the engine. If the starter doesn't spin then either you have a dud battery or the starter is dud.
    But make sure the battery terminals are clean and tight before doing anything.

    Thanks for tests to try, will give it a go, still can't figure why it's fine once you get it going.
    Cheers

    You could do a more direct wiring for starter circuit, maybe clean out the starter. 30+ year old starter and wiring is pretty good service.

    I didn't know you could clean them out. I will definitely do that.
    I bypassed the whole wiring, ignition etc and put a short wire through another push starter switch
    from the + to the solenoid and it seems really strong. I will leave it a day or two and see if that was
    the problem
    Thanks
