controller fried? no B+/M- voltage

[damon561]

1994 ezgo, not sure of model ( custom body) , series motor. Cart will drive fine for a few minutes in the morning , then clicks but won't move - if you let it sit for an hour or so it will repeat. nothing is getting hot and I have done the ITS test which shows correct voltages. Battery voltage is 38.1, individual all over 6.2, solenoid showing good according to troubleshooting charts.The only thing I can find troubleshooting is very low ( .5-1V ) voltage at B+ to M- terminals - according to troubleshooting chart that indicates a bad controller. I pulled the case off the controller and see nothing obviously fried and no corrosion- I am assuming one or more failing Mosfets but can't find anywhere to buy those (PMC-NE8d) . It is a 4 post controller .... Am I correct about the controller? Any suggestions for Mosfets or am I stuck buying a controller?
