FJ62 Dual Battery Question (1 Viewer)

[Boom62]

Quick question... I want to run a dual battery setup in my FJ62 and was wondering for others that have done it where they relocated the "Air Silencer" (Part #17301B Below). Or if I even need to move it, or if you recommend I just desmog

Thanks,
W

some people have removed the silencer entirely and replaced it with a small air filter.

I recommend the desmog. You can keep your cats if you want, but get rid of the EGR, smog pump, and silencer. If your FJ62 is like mine then:

• The EGR system is chocked full of carbon deposits and not running well
• The NLA check valve that your smog pump pushes air into will crumble to dust when you try to service it
• The smog pump itself will eventually fail which could result in damage to your engine or the other components driven by the belt

The best part is that you will still pass a tailpipe emissions test so it's not like you really need those components anyway.

Thanks guys, looking through some old threads it looks like I'll just go with removing the silencer and leave it at that.

Still think I'll do the desomg one day, just not today...

What are your plans that involve 2 batteries? Winching? Stereo? Power inverter? Do you wheel the truck in the mountains, or in swamps?

When I added a second battery mine just went into a box somewhere.

If you hook 3 silencers in "series" your truck will sound like a Prius. JS

I just de-smogged because this truck will never leave Oregon.

BTW...............I have an extra Blue Sea 5511E dual circuit plus switch here I can make you a deal on if you haven't bought one yet. PM me if interested.

I want to do the same thing, but I live in Cally... I bought the tray just need to...do something!

I'm driving to Argentina right now and I'm doing the same which means my access to tools and equipment is very limited.

I'm planning on taking off the silencer and the radiator overflow tank. I'll eventually make new brackets for them and mount them somewhere else. I am a bit worried though for the overflow tank. Will the heat from the engine damage it if it gets close?

 

[Kmonty66]

I think any of the places that you would "need" to relocate it to would not be to hot. You have options, especially if you do the de-smog. I will post a picture of mine later today or tomorrow. I'm in Cally, so I have to keep my smog crap!

@Kmonty66 That would be awesome, thanks

I did a de-smog and a dual battery installation recently, and here are some pics of how I arranged things. The desmog frees up tons of room! I mounted the overflow tank on the back of the battery tray, and cut out a spot for it in the bracket/shelf I made for the fuse box.

I removed the air silencer and installed a stock battery tray on the driver's side. I relocated the radiator overflow to the passenger side fender behind the air intake near the passenger firewall.

I used a blue sea 7622 relay and blue sea circuit breakers. The blue sea circuit breakers are made by eaton and can be purchased for around $39 on waytekwire. The blue sea ones everywhere else are marked up inappropriately.

This is the one I used for the each battery. Switchable and good quality. I see people using really cheap circuit breakers on $40,000+ vehicles and it baffles me.

Nice, well done. Here a couple of mine as promised. Full install credit goes to @orangefj45 Thank you!!

Hi guys, thanks for the pictures! So I drove around Panama City for a couple of hours yesterday and after a lot of bargaining (I hardly speak Spanish), I managed to find a battery tray and something I think I can make into a support arm.

The hostel where I'm at, allowed me to borrow a drill. So in a few moments I'll start. Will post pictures later so you know how it went. Cross your fingers

 

[Frkens]

I've got a bad sunburn, I'm dirty as hell, I had to stay another night at the hostel to keep borrowing their tools but it's done! The wooden cabinet is how it used to look.

 

[Frkens]

And the last pics... The battery tray came without any kind of support arm so I had to be creative.

 

[jackhossross]

As I begin my dual battery setup, I truly appreciate all the pics in this thread. Really helping me with a plan to tackle mine.

Cheers and beers.

 

[mobydick]

I have an extra one of those Blue Sea dial switches if anyone needs one. Brand new never installed. PM me. I'm about to go through my parts bins to sell a few things.

 

[jackhossross]

Alright ... what is this and where do I move it?
