Clearances

TDC sensor to pulley teeth.............. 0.6 to 1.0 mm
Dizzy cam to phase sensor..............0.2 to 0.3mm

Prob just remove em, check curent flow with ohmeter or summat though I dont know how lol... clean up the faces with wd40 or summat, refit and gap???

You can see the phase sensor obviously has to be pretty accurate, and be careful as thewires probably are very brittle now.... Im sorry if they werent such delicate (when old) parts and easily buggered up..I wouldve run down to swop em over mate. But I dont fancy my chances lol
