What is the correct name for this breaker?

[crazy charlie]

I may have to replace this...whats it called? Everything fine when winterized.Now my Yamaha OX66 on my Grady starts and tilts fine but nothing else is working.Is this a main breaker?? Resettable or replace?? Puzzled . Charlie

I would use a meter to see if power is not passing before replacing

It's most likely just a standard push button breaker under the cover

That is the circuit breaker for the main power of the boat. Trim power comes off the motor side.

Pretty robust. Have not had an issue with mine. Pull the two screws on the transom and put a meter across the terminals on the back.

Thanks guys ,will do.Pressing the red button is basically a reset??

 

[alldodge]

Yes

It's on there for an unexpected current surge. If that happens the internal circuit breaker opens. As alldodge said, the button is to reset it. Before you go to a lot of trouble push it and see if it resets. If so, fine. If not one of 2 reasons: Broken internal switch, or continuous current overload.

Thanks, kinda weird that all was fine when winterized and it's just been sitting. Puzzling but will check .Thanks Charlie

Not much room without removing a battery but the connections inside the breaker that I can see are pretty crusty looking. What setting does multimeter go.on for a test? I have a Greenlee DM55 ,I'm thinking V--20? Never used a meter before. Lol. Will try to post a pic of crusty breaker

 

[crazy charlie]

I did get readings at that setting on the meter.

 

[alldodge]

yes, 0-20 you should see full Bat voltage 12.6 to 12.7
Black probe on Bat ground

 

[crazy charlie]

Thanks so I don't touch both connections within the housing? Both are red

 

[alldodge]

no, red probe on one of the terminals and black probe on ground of Bat of the block

Put red probe one at a time on each terminal of the breaker, they should both read the same

 

[crazy charlie]

Ok ,it's seems like the connections are the issue. Too crusty. Neg on battery and probe on 1 connection reading was less than 1,when I moved probe half inch from the connection 12 came up

 

[alldodge]

Remove the breaker from wires and clean everything up and reinstall

When you have breaker off and clean, put meter on ohms scale and touch one probe on each terminal. You should read 0,0 ohms

Note, don't do this test with any wires connected to it

 

[crazy charlie]

Ok got it. Just testing the breaker alone at that point. Thanks. I just sprayed it down with deep creep Seafoam and will tackle removal tomorrow. I don't think connections are coming off easily. Thanks again

Would jumping the breaker confirm this is the issue as well or is that a bad idea?

Yes, but keep in mind jumping it with bad connections may not change anything if jumper does not make a good connection

 

[Scott Danforth]

Just clean the battery cable connections

 

[crazy charlie]

Got it ,Thanks again

Hoping I don't sound like a complete tool here but should I be able to temporarily connect the 2 leads together after I remove the breaker and until I get a new breaker if needed?? Just to keep my bilge pump connected for a day or 2 ??
