HELP!!

Its so easy a caveman could do it





Make sure to use shrink tubing. And solder it if you know how.

Please explain why you did not use one? Pros vs cons, thanks.

Pros: if for some reason your fishfinder were to draw extra current, you could destroy it. A 3A fuse will prevent this as only the fuse will blow.

Cons:Extra connections that could fail or become loose. Also, if you are out on the water without a spare and the fuse blows you can't use the GPS unit at all.

use a heat shrink butt connector for the best sealed connection.

Recommended by Raymarine for my fishfinder is a thermal circuit breaker instead of a fuse. They are cheap even at West Marine and I like that if it ever trips I can reset it instead of being stuck on the water without a replacement fuse.

Don't feel bad. No one is born with knowledge. It is gained.


Click the link to a sample picture of a in-line fuse.

One line to battery positive, and other to the device. The fuse must be rated by the manufacturer to provide proper protection.
Unless you make a mistake of using different batteries with higher voltage rating, you really don't need fuse protection. Or if you charge the battery with device connected, thus the charger puts out higher voltage.

In saltwater environment, the less "exposed" connection points the better.
All of the connections should be sealed with shrink tube or plastic paste.

A dab of electrical grease at the monitor connection is recommended too.

I hope above helps.
