RE: [alfa] No Brake Lights On '91 164S

["Gwynne W. Spencer" <gwynnes1@xxxxxxxxxxx>]

Measuring the voltage without a load will not lead to a solution if there 
is resistance in the circuit somewhere!  Connect a bralke light bulb across 
your voltage tester leads while making the measurement and do not be 
surprised if the voltage is way down under that condition.
