1980 Questions for all other cars 200000 miles

This is not a car question and I am really searchng for someone who might steer me toward help/ I am the caretaker for a remote fishing lodge on BC's west coast. There is an Allison 70kw diesel generator that I use as a back-up but it blows a fuse in the control panel every time I hit the pre-start button then the ignition. I realize this is a car repair forum but can anyone please steer me in a direction I can get assistance possibly. Thanks greatly. Getting a certified mechanic in here is virtually impossible and would be brutally costly, so if there is any help and I can fix this piece. Great!
Thanks
