Re: [MBZ] How far can you drive a diesel with failed charging sys?

[Vernon Ritchey]

This is a good tip from Trampas.  If the alternator light doesn't come on 
befire you crank the engine, the light is unreliable. In other words, it may 
not light when the alternator stops charging.  Don't ask how I know.

When brushes go bad alternator/battery light will not come on. To
temporarily fix problem hit alternator with a broom stick, hammer handle,
etc. This will give you another 50-60 miles.
