Measuring Voltage At Fish Finder Head

[BG RTR]

How do I do this? It's an eagle cuda with 5 pin slots on the power cable. Unit was fine and mid day would not power up. The fuse at the battery is good so I want to be sure I have power at the head.

Do a Google search for an Eagle Cuda power plug and you will find a drawing on which pin is which.

If you have a volt meter  select DC voltage.  Connect the black lead to a solid ground.  Only one of the pins will be carrying voltage, just touch them one at a time with the red lead until you find one with around 12 volts on it.  If none of them appear to have voltage you may have a wiring issue.

Thx! I'll see what I can find in regards to which pin carries power

Hold the plug with the flat spot down and eliminate the center one.

The positive conductor is the second one on the left side clockwise about 10:00

The negative conductor is the second one on the right side counter clockwise about 2:00

They are across from each other

Thanks!  I found a diagram on-line that some had drawn.  I hope to find time this evening to test..

Well I have 12 volts at the power head. Looks like the old cuda is a goner! I'm starting the journey to find a replacement. Nothing fancy just need band for the buck !
