You must bolt the ammeter terminals together (the large red and large black with eye terminals) and BE CAREFUL, those two ARE NOT FUSED except for the "fuse link" which is darn poor "protection."
Okay so all 7 of my fuses seem to have power. But I have no tail lights and no horn. I suspect that broken orange wire is to blame. I am studying the manual and having a hard time understanding the wiring diagrams I also have no idea which fuse is THE fuse. Since everything I see online indicates there are supposed to be 8-10 fuses and I only have 7 slots in my fuse block.
