This is a no brainer to help get you more electrical power without having to
rewire the entire car.  Not that there's anything wrong with that!

This is a bolt on installation that replaces the original Lucas 43 amp alternator
with a Bosch style 55 amp unit from a 1980 Ford Fiesta.  These are available
at most major parts outlets if you request the Bosch 55 amp version for that year.

Please note:  Update July 22, 2008

I have just discovered that some earlier TR6's may require some sort
of wiring modifications, so unless your plug and harness looks exactly 
like mine in the pictures below, there may be additional wiring work required.

**** Viewers are warned that if they attempt any mechanical repairs or modifications,

This is the original alternator.  Rebuilt well, but it has it's limits.

 

This is the replacement Fiesta Bosch unit.  It bolts right in with no changes needed.

The plug fits in exactly like the original Lucas unit.

The mounting position and adjustment are the same.

This couldn't be any easier and it's about time that happens for a change.

A nice neat and simple installation.  This definitely made a difference with the
new Dan Master's Headlamp Relay Package and TRF Halogen PL700 headlamps.
