starting issue

[Dadsredwagon]

replpaced solinoid two times , here is my issue 65 230 motor. turn the key click like starter wants to engage, nothing , if you try again you get dim ligts on oil and gen light but no click or anything.... open the hood disconnect positive battery cable, reattached sometimes this works, but mostly I have to jump the solinoid using a screw driver between the battery cable post on the solinoid and the right termimal on the solinoid, again this only works sometimes. so any idea's ??

thx..
