i had originally diagnosed the jack as having bad batterys and the customer chose to put them in themselves. then i was called backout cause it wasnt working, i got there and it worked fine, and i got called back the next day (keep in mind that this is the first job ive done for this company) turned out the customer only replaced two batterys ,and the other two were caked in corrosion. i hate raymonds and thanks for your help. woul any one know where you could get r a y m o nd di agn o s is software
