2003 Four Winds Hurricane - test plug is showing all outlets with an "open ground" while on shoreline power. But, when switched to the generator power all outlets are "correct". Then, when back to shoreline, "open ground" again. So I went to the breaker panel with my meter. While on shoreline power, testing from hot to neutral is 120v, but from hot to ground is 60v. However, when on generator power, hot to neutral is 120v and hot to ground is also 120v. Is this normal (ie; ok?). I'm wondering if this has to do with the transfer switch set-up? It's obvious a ground exists for either power source, since I'm getting a reading from hot to ground on my meter... but why only 60v when on shoreline power, and 120v while on generator? Help!
