My mosfet board came in tonite at 5:06pm 8) and I got it put on by the headlights of my truck, and.....no dice :'(.
Have any of you had the headrig not move until the speed pot is at half throttle or more and what was the cause?

Also my hyd. tensioner is not holding pressure, like losing 300lbs in 3 minutes, bad seals or low on fluid?

Sorry but I had to vent a minute, I only thought I was done with all these nit-picky problems, but have since learned better. :-\

That is a simple fix with a rebuild kit.  It uses "square O" rings, so do not try to use standard O rings for a fix.

 
Here is a picture of my blown O ring.  The kit will have a new piston and everything needed for a complete rebuild.

Does your head move easily by hand after you remove a wire from your power feed motor?  (removing the wire removes the shunt (electronic brake) that the motor provides.)  If not you might have a splinter wedged somewhere or possibly a frozen cam follower.  I am just saying that there is always a possibility that it could be mechanical rather than electrical.

Does the head rig move smoothly and have the full range of speed once it starts to move or not? Just thinking that it could be that the dial on the speed pot is no longer aligned with the markings on the board, I know mine isn't, I'm thinking the speed pot on my 70 also has some travel before the head starts moving.

I know how frustrating little issues like this can be esp on a machine your not familiar with, and not just used equipment I've had my share of frustration trying to get the bugs worked out of brand new equipment.

Don't loose hope you'll get this thing running like it should before you know it. 8)

Don't really have full range of speed, it will speed up but not really slow down.
Magic, I figgered its just a bad seal in the tensioner.

Right, but use all of the kit and rebuild the entire unit while you are in there.

Did you have a looksee at the forward reverse switch? it could be the issue as well as or the pot. I just got my new one from fedex today. My pot has a dead spot in it my right speed ain't there when sawing frozen hemlock to slow then stopped then to fast. Keep a sharp blade and go for it :D. That was my fix for the last few days. and its been awhile since I greased my swtichs so I would bet they are worn ::).

Magic, I figgered its just a bad seal in the tentioner.

It could also be a worn or improperly adjusted belt on the forward-reverse motor.  It does not quite sound like it but it's worth checking. When I bought my mill, that belt was shot and produced intermittent operation of forward movement. Reverse was OK.
It's the going that counts not the distance!

I might have this figured out, I was on the phone with Mike at WM for 45min tracing this down and found a wire in the wrong spot causing the ground not to be constant, got all put back together and it worked but was jerky and then .... it quit altogether, I had run the battery dead while working on it and my battery charger is dead as well.

Gonna charge my battery at my buddy's shop and try it again. :-\

Check the diode should only have continuity in one direction. Mine went bad and took out the board. Also have a look at the lights on the board to see what they are doing they help with problems My pot is going again or I have a bad connection as the input light goes out at certain spots on the pot. New one came Friday.

Never dealt with wm Mt vernon, but I can tell you about the guys in Indy. Have a test light or voltmeter ready and call them. They are very good at troubleshooting over the phone.

I agree with pineywoods, my friends lt40super hd he got used had some electrical issues when he got it, he called up the indiana boys and they told him just what to do to get it running right.  Good luck and stay strong, it'll come together.

Yup, 45min on the phone w/ WM Indy got me 10sec of run time.
Something is wrong I just don't know what.

I hate electrical stuff!

I bought a 1988 gooseneck trailer this weekend, tried to get some of the lights working for the drive back.  Man what a pita that was I might just better rewire the whole thing.  The wiring is all sorts of cattywampus.  Did I mention that the previous owner liked scotch-locks alot?  :)

Don't think about the entire "nest".  You are only concerned with one wire at the time. 

You sound understandably discouraged, but Indy can and will walk you through it.  Those guys are good and know their stuff.
