I just had my second rotor failure in an LBC - and in 25 years of
personal vehicle ownership/maintainance it has only happened on LBCs.
Rotor was in use for two months (about 1500 miles). Rotor was listed
with a TRF Lucas P/N but was not marked as such (I was told at the time
of purchase that this is the only brand available - at least from TRF).
This was for a TR6 engine.
Why would a rotor fail? This is a simple plastic part with a flat piece
of brass rivited to it? I assume that it shorted out to the dist shaft
although I was unable to detect a short using my multimeter.
Question for the overseas listers - Are there other brands of rotors
available (i.e. Bosch, etc)?
After about 15 to 20 minutes of trouble shooting the wrong items on the
side of the road I swapped in a spare rotor from my previous GT6 engine
(Delco dist). Once I rotated the wires 180 deg )rotor tip faces the
opposite direction the car fired up and purred even though the rotor is
about 1/16 in. shorted from center of shaft to rotor tip.
