Kind of from the hip, but power to the starter is dirrect, the chassis solenoid will not handle the start load. But will handle the ignition power to run the starter solenoid. As to the second problem I suspect the same as the first, maybe coincidently, but if one solenoid was bad at this age the other could be also.
