50amp mini breaker lifespan

So I had my rig out to shake it down after dealer repaired the warranty stuff and make sure everything was operating as expected......

Lo and behold the "main slide stopping while retracting" issue I brought up to my tech seems to have gone dismissed....so now not only is my slide stopping, now my 6 point is stopping while retracting...

given that it all works and is not leaking I'm gonna assume its either the breaker or a bad ground....ill address both next week when I am doing the bearings....

any way,what is the average lifespan for one of these things...I mean my rig is only a year old?


also for those who have replaced them did you just buy one from the auto store? I'd probably be inclined to order one (or a couple) from amazon if anyone has a part number or link for the correct one...

Thanks
