Been having Issues with a Prentice 2670 . If the machine sits for more than 1 day it will not start without a boost. I have noticed while attempting to diagnose the problem that I have 10.75 volts at the negative terminal, 1.68 volts at the positive terminal and about 12.48 across both terminals. Why does my negative terminal have voltage? What is the best way to diagnose and fix this issue?
