Other then the power and loss ground, only heat related failures of the KAM, which is really a general failure of a larger chip because the KAM is only a 512 byte address space within 1-2 chips totaling 64k. The ram chip should be marked 81c61.

Basically, what happens is the CPU and components are only rated for 180 int. use. When the weakest link fails from heat (eprom or ram) you get a KAM failure which is really a disguised component failure of ram.

I would be happy to e-mail the above pdf to you.

Steve, I agree. I always thought redoing bad work done elsewhere was good business.

Someone else mentioned it and I thought I would agree, look for the harness being pinched somewhere.
