Have a 1977 444 - Heres what I did since engine rebuild (had it rebored 1 over cranckshaft miced down 1 under). Did not run smooth at high throtle, ran good at idle. Found the generator field stud was loose (broken insulator inside, possibly grounding out) replace the armature, field stud and brushes. Started it up and found thel headlights didn't work, long story short had to replace the ingnition switch (loose connector on back, the one going to the lights) Since I replaced the ignition switch (still no lights) and now when I turn it over the thing dosent start it makes a grinding /clicking noise and it sounds like its comming from the solenoid?? I had the battery checked out at auto store and the guy told me it was still good. I can start it up with jumper cables from the car, so what gives?? Maybe the guy at auto store was wrong?? Get a new battery or could it be the solenoid?? Any help greatly appreciated.
