I just bought a 99 763 that has some sort of electrical problem. After starting and leaving it running for a couple of minutes the thing just turns off. The hydrolics are also not operating for some unknown electrical problem. I had the hydrolic system checked out and was told that it was fine and an electrical problem is to blame for the non-operation. I'm thinking the two problems are somehow related and was hoping someone can point me in the right direction in order to solve these problems. Thanks in advance for you help.
