.4 volt is a bit on the high side. Closer to zero is better and .2 is acceptable.
Sounds like a dirty ground. I just went through the grounds on my truck and wound up taking them all off, taking a brush to them and a dab of contact grease and reassemble. Amazing how much errant voltage went away.
Your description is lacking a bit of info for me. Others might be able to decipher what you mean, but I am a bit lost.
Is the starter making any noise at all?
12V conversion with a starter relay/solenoid?
Is that a 4 post with the resistor bypass?
Do the cables get warm when trying to crank?
