Lowrance HDS wiring question...

[cupper]

So, I've been trying to install my new HDS-5 unit for the past week. I've been very busy and the wife's been sick so I have had to start and stop the project several times. Last night I was finally able to finish it up (or so I thought). I connected the power cable to the battery, hit the power button... and nothing. I read and re-read the instructions and I am at loss for what I've done wrong. I have a simple set-up and I do not need the "NMEA" stuff hooked up... I just need it running posative and negative to the battery so that is what I have done. I taped down the multi-colored wires as well as the yellow wire next to the red and black. Do I need to connect the yellow wire somwhere as well? The instructions said it was for something else, or so I thought. I have checked the fuses, the connections, and the battery. Can anyone see something that I have done incorrectly? If anyone has any advice for me I would really appreciate the help. It is killing me that I have not gotten out yet... every time I take on a project like this I always get thrown curveballs.

Thanks!

I think the yellow wire is only used if you are networking multiple units. You shouldn't need it. If the fuses are good, then I'm at a loss also. You don't happen to have a console with a master power switch do you? If your wiring to your fuse block under the console, this needs to be switched on for the red wire to get any power. In any case, use a volt meter to see if you get 12-14 volts across your red and black wires.

I agree, use a voltmeter to make sure you're getting power through your wires and the plug. If you can, try your unit in someone elses boat, or try someone elses unit in your boat. The power plug for the HDS is the same as for the last couple generations of LCX, LMS, and x-series units so there's lots of options if you know someone with those units. Good luck getting it sorted out.
