[Vwdiesel] clock

[Pam & Doug Boes]

What's up with my clock? It used to keep great time. Then I had an 
alternator brush problem where everything was dying as I limped the 
Caddy home. After replacing the brushes, I noticed that the clock wasn't 
running anymore. Now, if I twist the hands to the correct time, it runs 
fine for about three hours after I stop. Then it stops. What is the 
clock telling me? Is its condition related to the brushes wearing out? 
What do I need to do to make the clock nornal again?
