1974 Starcraft Holiday with Volvo 130 Starter Problem

[1974StarCraftHoliday]

Okay, so I recently just purchased a 1974 Starcraft Holiday with Volvo 130. All I have done so far is cleaned it up and cleaned out the gas tank and got new fuel lines, but when I turn the key nothing happens, so immediately I thought the starter must be bad, so I bought a new starter only to find out that the new starter doesn't "start" either. So I looked at the wiring Diagrams and traced some wires, I have power going to the starter and power to the ignition switch. When I turn the key 2 out of the 3 terminals become electrified (the one where the power comes in, and the one that lights up the oil light and the light by the tilt switch.) but the third terminal which goes to the shifter and then back to starter, and from what I have gathered I think this terminal should be " hot" and send current to the shift lever to make sure it is in neutral then to the starter to engage it. Is that correct? Any information will help. Also is there anything else I should do to the motor since it has been sitting for so long before I try to start it?
