Quoted from MaxAsh:Possibly silly question: When I removed all 4 GI fuses, I still tested for continuity across the empty fuse holders, and found continuity. Is that normal because it's an AC GI circuit? Seemed strange to me. That made me think there was a short somewhere in the chain, but maybe my tired brain is just off.
I think it's because they are all tied together at the transformer. See page #23 of the manual for the wiring.
