seddon 401

We have tested the output and as far as we know its fine . But the over complicated electronic control system shuts the generator down after 45 seconds . We have established that it will work as a fixed speed generator with a generic AVR we just dont know how to wire it in or what to get 

Anybody  got any experience with generators . I have an Air log generator with water damage to its rather over complicated electronic control system . I need help to chose and wire in a modern AVR   to make it work . Ideally somebody in South Devon I'm happy to donate money, beer, use of my lathe,welders. repair things on your vehicle I'm just crap at 240v electrics   

Just joined . Like all new members of a forum looking for help with my little collection .
