mh depending on motor ive had similar probs,wouldnt start etc,changed out for my spare,still wouldnt work,hooked up a manual switch direct from bat to get me going,then played with later,endid up that the relay wasnt working i think so u only got power from relay feed but not full power,played with it for a while,wiggled all the relays then suiddenly it just started working ok again

maybe something like that,i found that by putting a light tester on the solinoid wire and trying to start,all u saw was the slightest light that was very very dim,hope u understand what im trying to say and it helps
