Are you getting 12v after the fuse?

I would say send it back to hummingbird, but it doesn't look like they service that model anymore. Even if they did, at $120+ I'd just buy a new fishfinder.

Yep, but I don't have 12 at the connector to the head unit. I have .9. That's not normal right?

Ohm out your fuses sometimes they look good but are bad. redo your leads at the battery and use some contact cleaner on the connections at the head unit. spray the connector at the head unit and plug. Then put some dielectric on the head and cable. Also check the wire for any signs of or broken wire or worn spots along the length of wire. Also check the ohms between both ends of wire this should help find the bad wire. Hope this helps.
