Grove SM3884XT:
SM42RT won't move Fw or Rev

I just bought a 1988 SM42RT lift. I have it running great. Everything is now working except for forward and reverse. When engaging fw or reverse from the lower control box, the alarm sounds but no movement. The upper control box is missing. Any help will be greatly appreciated, including where to find a replacement upper control box or any other helpful links. Thanks in advance.

Fact of the week
The Michelin Guide with its star rating system originated in France in 1900. The guide was created as a marketing tool to encourage more car travel and consequently increase the demand for tyres. It initially contained maps, tire repair instructions, and lists of restaurants, hotels, and mechanics.
