Hello, all: My '72 Eldo occasionally responds to the starter button with a loud click. Can happen once or several tries in a row, then will fire up as normal. Seems to have plenty of juice to spin the motor, more like the starting relay is hit and miss(?) Also a bit more apt to do it on restart on a warm/hot engine than on a cold engine, though it did it to me cold last night, thus prompting the post. Doesn't seem to be a function of weak vs strong battery. Suggestions?
