Apologies for resurecting an old problem..... I'm in the process of sorting out my intermitant starting problem - all the necessary bits purchased. The instructions, gathered from a blatchat link, state that I should "Detatch the smaller wire (i.e. NOT the big red one) from the rear of the solenoid...". This is to go to terminal 86 on the new relay. The problem is that my solenoid has three terminals on it, with: i) big red wire and smaller wire, ii) thickish black wire - but smaller than thick red wire, iii) short thin wire going into the starter body; which means I have three candidate wires. Can anyone advise which wire I should move to pin 86 on the new relay? Thanks
