Default Humingbird polarity ?

Anybody knows what happen if you connect your power lead to a HB sonar unit backwards?

Trying to move waypoints to another unit and the power plug I have goes in both ways.
Trying not to have to sit in boat to do this, easier on the bench.
TIA

Al

A guy on another site did that earlier this spring. No damage done as he realized his issue before powering it on, or attempting to power it on. He did blow the fuse in his marine radio though.

It won't power up. Don't know why there would be any other issue, if there were I imagine they would make them one way connectors like a transducer. Helix power connecters have a ridge on the side that goes up.

My 597 got hooked up with reversed popularity and went poof. I replaced it with a Helix 7.

Could check polarity on the boat at the plug

I reversed battery termiinal wires, didn't turn my helix 5 on, corrected connections, replaced a few blown fuses including on vhf and f150 and t9. 9. All was well after my fupah.

lol Reversed polarity wasn't very popular with me. I was surprised since I thought a diode should have been in the circuit to prevent zapping my 597. I'm going to open the case sometime and check for a blown fuse. If I find one and replace it I will have a GPS mapping system for my Yamaha sxs.
