Why can't I run two humminbirds..

on one power feed? The hlix 7 is for my sonar and has the transducer, my hlix 5 is power only, used as a gps with lakemaster. Mounted side by side. Everything is fine except- when i power up one, it causes the other to shut off. Wire gauge can't be the issue, it's easily thick enough. The pigtails are spliced red/red/red, black/black/black, that circuit is properly routed through the sonar fuse on the panel, and its not blowing. Any ideas?

What size wire are they fed by? If they’re connected through the harness at the dash you’re probably losing quite a bit of voltage through all the connections.

I’d put in a 12 gauge feed from the battery straight to the units, spade type fuse holder with hummingbirds rated fuse in it at the battery, and all connections soldered and heat shrunk. Doing so should eliminate a ton of problems going forward.

Just my $.03, YMMV
