I purchased a cherry 94 LCC last week with 98k miles. It has the standard center diff lock but no front and rear lock. Probably never been off road. When I put it in 4L nether the center diff light nor the ABS light come on. To test it, I put it on 4 jack stands, and when in 4H the front and rear wheels both pull, but when I stop the front wheel by hand only the rear wheels pull. Normal of course. When I switch to 4L and try this I cannot stop the front axle, so this tells me the center differential is working normally I believe. Am I wrong? The dealer said the light was not supposed to come on, but he was wrong of course. An opinions?
