I have the same problem with the Intellitec EMS board with resistors falling off and a burnt board (see pic below, before I wiped it)only one left after wiping it.
And as far as receiving a supply of miss-labeled resistors this is not true at all quote from Intellitec.
As far as Intellitec company goes I would not recomend them to anybody as they will not warrant their product, come up with every excuss they can dream up. (ie:-power surge)
Had it checked by (USAF)electronics expert
he said it was more likely caused by a cold solder joint.
I have a couple of their emails as proof.
I am going to take the issue up with Winnebago.
For the time being, I made temp repaires to the board.
We have a brand new Itasca 2006 Ellipse delivered in 2007 but since that time it has been at the factory or dealer trying to get things fixed.
We have not used the coach yet??? Another couple of months to get it fixed, then hope to use it.
