Flaky odometer - '88 Spider

[PaulS39832@domain.elided]

Thanks everyone for suggestions on troubleshooting my odometer and trip meter 
which stoped functioning short of 100,000 miles.  The meter resets OK, but 
will not advance any longer.  I have removed the instrument cluster, and 
examined the odometer motor electrical connections.  They look good.  The 
gears that the motor engages on the odometer and trip meter turn freely.  Any 
ideas on how to determine if the motor or sender unit are defective.  Can I 
apply current to the odometer motor connections to see if it will turn?  How 
much current/amps, and to which wires.  There are three wires, two red and 
one green.  I may take up a fellow digester's offer to send me a spare 
cluster, but enjoy figuring out how these things work.
