A friend has a 1993 FZJ80 that has been is storage for the past 5 years. He went to get it out and it started up after some coaxing and he drove it around some. Ran and drove fine then went to test the 4 wheel drive system. Moved the High/Low lever and engaged the center diff lock button. The truck will not move now. Can shift into reverse and drive but the engine just revs like it is in neutral even after shifting the transfer case back into High or Low - it will not move. The truck has had some electrical gremlins that he was never able to chase down. Window fuse keeps blowing so none of the windows open etc. The truck has relatively low miles, 154,000 and was driving fine until the messing around with the 4 wheel drive. Could a fuse blow that has something to do with the transmission? Thanks in advance for any input that can be given.
