Miss Jazzy Posted September 3, 2019 Report Share Posted September 3, 2019 Just replaced my tm and also traded out the plug to a battery tender plug. Also added a 30a breaker from a fuse holder. So all connections are new. Problem I'm having is after just a few minutes the breaker trips and it takes a little while before I can reset it. Battery's are blue top within a year old. TM is Ulterra. Had e batteries tested and all was good. Only thing I can think of is replacing the wires from breaker to plug, maybe they're corroded under the deck and not getting enough voltage?

Did it work on your previous TM, e.g. no problems? Now, it is happening? Are you using a 1/2 ALL with the engine motor? Are all the connections secure...remember, it only takes a slight bit of looseness (if that's a word) on a ground or a pos to create a hot wire and the breaker will go. Is the breaker ok? From there...you just have to go step by step.... 1.) Check your bridge connection on the batteries and be sure everything is tight with the wiring. 2.) Same with the connection to the battery tender plug 3.) Same with the breaker Do the above and run the TM on the boat (you can just deploy it and check while running on the trailer) at high speed to check. If none of the above work....I'd pull new wires, but, first I'd run them above deck to be sure the wiring is working well. Enjoy the hunt.....electrical stuff makes me crazy.... dc Link to comment Share on other sites More sharing options...
imsnookyrd Posted September 3, 2019 Report Share Posted September 3, 2019 I think the breaker is too small mine is a 60amp. Link to comment Share on other sites More sharing options...

hurricane Posted September 3, 2019 Report Share Posted September 3, 2019 Agree, pretty sure 30amp is too small. Check your model and see what they recommend. Link to comment Share on other sites More sharing options...
Miss Jazzy Posted September 3, 2019 Author Report Share Posted September 3, 2019 Thanks, I’ll check and make sure it’s a 30. I know it had a 30a fuse. Link to comment Share on other sites More sharing options...

fin-addict Posted September 3, 2019 Report Share Posted September 3, 2019 Breaker too small, need 60, know you have heard this before. Bypass breaker and see what happens as a test. Jmo Link to comment Share on other sites More sharing options...

Bypass breaker and see what happens as a test. Jmo This sounds like the correct thing to do. During your test or after replacing with a 60 amp breaker, feel the wires after a few minutes. If they are warm, that is an indication of too much resistance, which usually indicates a bad connection or corroded wiring. Hope it's just the breaker.

Yes, 60 is probably the right number based upon above..... Here is the link to amazon.... amazon link dc Link to comment Share on other sites More sharing options...
Miss Jazzy Posted September 3, 2019 Author Report Share Posted September 3, 2019 Thanks again, checked and turns out I have a 50 amp breaker so a new 60 is on the way. I also checked and cleaned all connections so we'll see next time on the water. Can't run it on the trailer, it'll hit the trailer when deployed.

finbully Posted September 7, 2019 Report Share Posted September 7, 2019 Once you get that straightened out make sure you open the breaker or disconnect the battery tender plug (the best) when you finish using the boat for the day because the tms draw a small current even when "off". I learned this the hard way... Link to comment Share on other sites More sharing options...

hawg Posted September 7, 2019 Report Share Posted September 7, 2019 Check the existing wire gauge that you have installed against the chart provided by triplec. If your wire is undersized, it will heat up and trip the breaker, whether it's 60 amps or not. I WOULD NOT bypass the breaker while trouble-shooting. It may be the only thing protecting your boat from a catastrophic fire in the bilge. Link to comment Share on other sites More sharing options...
