Cruse Control

[Jon]

I have the original 1978 mechanical cruse control on my bird. It
was
working but it just quite for some reason. I have traced part of
the problem to the vacuum pump and fixed that (The internal vain
pump rotor seals were frozen. I fixed that and now I get plenty of
vacuum but I was wondering how can you test one of these units
without driving down the road. Is there any schematics for this old
system? And is there a fuse on this unit somewhere? Thanks jon
