P1000 2nd battery dead, need help!

[ohiohunter]

Hi, all. I need a little help. I have a 2nd battery installed to run my accessories, stereo, lights, ect. I have the fuse block keyed and a battery isolator so my main battery doesn't go dead. But my 2nd battery keeps going dead and I can't figure out why. Nothing can stay on due to the fuse box being keyed. I'm throwing my arms up and coming to the professionals here on the forum. Any ideas from anyone out there? Thanks in advance for any help.

Does your battery (2nd) show charging?

well my blue light comes on when I start up on my True Dual Battery Connect but I'll have to check tomorrow if it is charging. I'm guess that the light is coming on but not doing it's job.

Isolate one battery from the other and charge the dead one, see if it'll take a charge.

Already did that, it did for a couple times and now it's dead and will only take a little charge and die quick. I have an Odyssey battery. I've never had a problem with them ever before.

That sounds lkke a bad battery. Autozone or similar can load test batteries. Just fully charge it before you take it in.

Repeatedly running a battery dead is what kills them unless it's a deep cycle. It may have just finally pooped out. If they were both of equal age, charge and type when you wired it, then it's the isolator. Whether manual or automatic type, somehow it's not charging your second battery.

Do all the accessories work fine when running then nothing with key off?

Right, that would eliminate the isolator switch question if they work when running.

It would say battery or ISO.itd take guess work out

I think you might be right. Or the "True" dual battery connector is not allowing it to charge. Thanks for the help.

Nope, nothing at all, dead as a door nail when running. And correct, no power when key off.

Iso then. Probably killed the batt as well. If it stays under 10.5 or so too long it doesn't come back

 

[ohiohunter]

Iso then

As in my True dual battery connector?

I have a two battery set up and don't use an isolator. If you do a lot of short 10 or 15 min runs then your isolator never charges the second battery. You would have to use a tender to properly balance those batteries.
Good thing you have the isolator in this situation though, one bad battery can kill the other one.

 

[ohiohunter]

Yes. Think of it kind of like an alternator on the car if you have a dead battery usually you'll still have accessories with it while it's running(or in this case while on) if nothing while running its isolator. Takebatt out and see if you can get it to hold a charge if not needs that too

oh, man. Spending some more money. Thanks for the help. Much appreciated.

I use it mostly on the farm and 10-15 minute runs is a constant thing for me. I guess I'll have to trickle charge it when I get it fixed. Thanks.

What kind of keyed relay are you using?

Since nothing wasn't mentioned about actual voltage on that batt that's a very good call

Fuse block?
