Greetings. Has anyone out there replaced the motherboard on a lt40 with a new H bridge?
Thanks in advance. Richard

I did this last summer.   Probably spent total of 3 hrs on phone with woodmizer but we got it done.    Their electrical service people are very good at speaking on novice level even though they are far above it.

I did it when I upgraded to accuset 2.
It wasn't bad. Just need to take your time and follow the steps. I used masking tape and labeled everything before I started.

If you look closely all the wires should be labeled in white writing.

Thanks for the reply PAmizerman and Logbyr..some great suggestions! One more question. Did you both do the pre-installation inspection? There are 14 connections to check before proceeding to the H-bridge replacement.
Many thanks,
Richard

I had an issue pop up during my annual tune up with the factory service guys.  They diagnosed the h bridge issue.   They said I had 2 options
1) take it to dealer for install 
2) call indy and have them walk me through it.

I chose option 2.     There were a few things we found during install that were not quite what book said it should be so having them coach me through it was a big help.   I don't have a ton of electrical competance.

Yes I followed the pre installation inspections

Yep had to do the inspection and cleaned up several grounds and had to remove the paint on other ground connections when I installed the new Auccset 2
