Had to fix my sisters and her husbands 66 coupe this morning.
They just recently had to have their car towed from their place to their local mechanic to have the starter motor recoed due to it playing up and not starting at all, cost $240 + plus tow
Well it packed it in again this morning out the front of my place as they were about to leave for the 2 hour long trip home
I removed the starter motor cable to find that it was probably original and in very bad shape with the insulation cracked and missing in and around the standoff brackets below the exhaust manifold right the way through to the cable lug.
Disconnected the lug to find that the starter motor post was buggered ie. stripped!
Pulled the starter motor out to test it with jumper leads to find the throw out pinion gear to also be in bad shape
Apparently their mechanic outsourced the reconditioning of the starter motor but should have picked up on all the other issues
Anyway ,pieced it all back together along with a newly made up cable to hear a horrible meshing sound on startup
Mechanic has been notified and is organising to personally pick the car up tomorrow from theirs to sort it
hopefully!
