does the voltage cut out on the 28 erskine have to be grounded to the generator or must it be insulated and not grounded? This is a positive ground system which I am not familiar with. My cut out is now groundede and I see a small spark when I hook up the wire to the amp meter. This is a new restoration.

First of all where are you? Second, can you take pics and post them here? got a name and phone#?
