I have a brand new battery in it a brand new alternator i checked the volts from the L wire off the alternator and its supposed to read 1 Volt its reading 10 volts what could this be?
Could you please explain in further detail what is the L wire you're referring to?

its the alternator pulley thats defective and in order to pull the alternator you a have to take off the piece with the hoses on it above the alternator and you can wiggle it out

This is a very good online manual for the Capri.

Could be the belt or tensioner(if so equipped) was too tight and then it may have warped the pulley or ruined the alternator. The belt smoking could definately be overtensioned or the bearings are shot in the alternator and creating the friction in your belt. Check the tension specs for most vehicles is usually between 1-1/2 to 2 inches of play. Thats how far your belt can be moved up and down by hand after tensioned. Too tight and you risk burning up bearings in other places or too loose and you hear squeeking and the vehicle may not charge properly or even overheat from water pump not turning well enough.
SOURCE: I just install another alternator on 79 mercury
was the alt new? how meany volts do you have?
SOURCE: low alternator voltage
it should be able to deliver 13.5 volts to 14 volts when engine is running. this can be caused by also regulator.it is there to regulate voltage generated by alternator.
