Trailer brake battery

3 posts in this topic

Hi all, looking to wire the fish house to take a charge from the truck while driving but was curious if I run power to the house battery AND the brake battery will it backfeed from one to the other when not hooked up to the truck?  If so did you just install a diode before the brake battery to prevent any current from traveling back?

Thanks,

I believe they will keep each other at the same voltage without some sort of switch(es) involved.

Stopped in at the RV shop last night and they did say that If I wired them both from the truck they would share voltage, and if I completely drained one it would drain the other as well.  He said one way diodes on each line would keep them separate or for safety I could just throw the diode on the trailer brake battery so that my house battery wont drain it but if my trailer brake battery dies or goes low it could back feed from my house battery.  I have a couple small batteries I may wire this and test it out with.

    • I won't be able to post the scores for this week until maybe Wed. so if someone else wishes to do so feel free to do it. In fact for the entire summer season I'm going to be pretty much hit and miss. So don't count on me the lake is calling and I have no computer there. My scores will drop like a rock unless luck prevails.

    • So I'm finally getting ready to get the boat wet for the first time this year.   I noticed last night the steering wheel is very tough to turn.  I did done research on some older threads on this site containing to my problem.   One tip I read was to check the big nut next to the motor on the steering arm.  Its printed on the nut -caution**tighten.  Some one said that nut should be loose.  Mine was wrenched tight apparently.  Does the warning on the nut mean , make sure its tight or do not wrench tight???  Btw it's a 05' mercury 115 if that makes any difference.   I will also re lube and clean the components also to see if it makes a difference.   Thanks for any input!!

    • I will admit to this :   there are a couple of crystal clear, cold lakes in Yukon,  within a mile or so of my cabin, where you COULD actually eat and enjoy pike. They did not compare to some nice Grayling but  you COULD eat them. I'm not a fish eater unless it is fresh king salmon or kind crab but quite a few folks would eat the pike. And I will admit to enjoying a chunk of walleye now and then so long as it is slathered in hot sauce and I have had 13 double Makers Marks. But hey!.....you fellas enjoy them!
