it kicks the drive out but the contacs do not hold and it lets go and spins

the contacs look like a washer on a shaft,then there is a u shaped flat bar the hits on both side to make contact

that shaft and washer spin as the u shaped bar rides on the edge of it making contac like a set of brushes,its made of copper and eats away from the arcing and pitts up the flats of the washer

the yota boys said you can r&r the thing and file the thing down and smooth any pitting and stuff and through it back together for a short fixbut its on the way out

some times its just got a spot or 2 on it and its the luck of the draw when it stops spinning for the contacs

mine was eat down to the nub,if you keep at it it will start the click.click every few clicks it might hit

if you take one apart you will see what I am saying

he showed me mine while it was apart and told me thats how it worked

try a jy for a good used one way cheaper than a reman or new,maybe take the one you got to a rebuilder and have them through a nippandenso silanode kit in it,(pardona on my spelling)
