When connecting the fuse and Hum DC Power Cable off the adapter does it matter which side of the adapter cord the fuse and DC Power Cable (red wire) you hook up to? Also, I assume the fuse is wired between the adapter and the DC cord?
-
You aren’t going to connect that Ethernet cord to your Humminbird unit are you?
-
Sorry, I meant the DC Power Cable.
-
I put my 3A in-line fuse on the positive (red) side of the power cord at the battery.

+1
Positive side closest to the power source is always the best option whether on the boat or in the house.
-
OK, I've cut the adapter cord, so I have 2 ends, does it make a difference which of the 2 ends of the adapter cord I hook up as the positive.
-
Yes it does. meter the cable when you have it plugged into an ac source and mark the + piece of the two cables. Then you can unplug from the ac and make the connection into the unit...

I have a hand held meter. How do I go about doing it??

Please STOP. Don't do anything until we get this sorted out.
I think Chuck missed the post about not being a AC hookup. Or maybe I'm not understanding correctly.
Your 898 is powered by 12V DC.
Option 1-- the original power cord supplied with the unit.(for use in normal install on your boat)
Option 2-- Power Cable PC 11 (optional purchase for use in your home with a 12V battery or 12V DC power supply to learn about the unit)
Which are you talking about?

Your meter should have a black (common) lead and a red lead.
You need to have the meter set to read DC volts.
Apply power and connect one meter lead to each wire.....make sure you don't short the wires together.
If the voltage on your meter reads -voltage, reverse the leads and the meter reading should now show just a voltage reading. The wire the red meter lead is connected to will now be the + side.
When the meter is reading - voltage, the black meter lead would be connected to the + side.
-
I am a bit confused now. Maybe a picture of what you are trying to (adapt) and hook up to the unit..

Thanx, Bob B. I didn't notice the - sign when I tried it before.

I'm glad BobB was able to help. He is very knowledgeable.
When I saw "OK, I've cut the adapter cord, so I have 2 ends, does it make a difference which of the 2 ends of the adapter cord I hook up as the
positive", I got nervous. I didn't think you would need to make any cuts. The two cables I described above each have red(+) and black(-) leads.
The output leads from a AC to DC converter should be red(+) and black(-). Sorry to cause the alarm.
