	Can you tell us what kind of "diesel electric equipment" you have. Brand name, model, model number, etc. Did you contact the seller, or maker?

	More info is needed about the generator, 800 amps could be over its rating but we need to know the nameplate data and the nature of the load(s) that it's supplying. Some types of DC generators are self-limiting so it's important to make sure that you're not asking it to supply too much more than its rating. __________________ “Tell me and I forget.

	Simple. Phone the equipment manufacturer and discuss the issue with their technical helpline. If it involves a technician calling in to assess and repair the fault, then so be it. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
