Thread: Humminbird 757 problems

I never know when it is going to happen, It is mostly likely to happen after it has been on 3 or 4 hours. Its kind of tough to change all that wiring out on the boat, but It can be done I know.

Don’t change the wiring out; just take the connectors out of the connector collector of the 898 unit and plug them into the back of the 787 unit by hand and test it that way.
