Not necessarily so, a spark means nothing. It takes 150 or more amps for the starter to work.bookman51 wrote:Tried it, got a nice spark when I connected the negative wire to the nub, but nothing moved. I gotta think something internal to the starter.
Go back to John Puckett's post and start from there. Make sure the battery is in excellent condition and that all cable connections are clean and polished. You will also need battery cables in excellent condition, without internal corrosion.
Battery condition check. Voltage drop test. Voltage reading across battery terminals. Take 2nd voltage reading while engaging the starter. 6 volt battery should hold in the 4 1/2 volt range while cranking over the engine.
