Back again looking for advice from you guys. Right now I'm having two problems with starting '75 Imperial and maybe they are related to each other. First, sometimes my starter has a real hard time cranking the engine, like it barely turns over. Battery is charged and when it catches engine runs beautifully and battery is charging. Seems to only happen when engine is hot but not always. Second, yesterday after about an hour long drive I was coming up the parking lot and it died, without warning, and wouldn't restart, but cranking speed was normal. Then on my final try it started as soon as I let go off the key so I could park up. Thought it was the ballast resistor but when I checked this morning it still looked good and resistances were good I think, ~1.2 and ~5 ohms. If not the ballast resistor, would that mean starter relay? How would I check that? Could a bad relay cause both issues? Thanks in advance!
