Hellroaring Battery Isolator / Combiners

I checked out Sam's and they have SC34DM Blue Tops for $99 bucks! It seems TOO Cheap. Is that the same as the D34m-950s? I assume so, right?

The system works! Not sure where you got that from...

I considered using a VSR setup, but after doing much research, decided that the isolator/combiner was a better choice. From what I gathered, relays can be a bad choice due to the high internal resistance and voltage drop problems and they have moving parts that can become corroded or welded. Isolator/ combiner does not have these problems. I know it cost a bit more, but I have always been one to do it once and do it right the first time.

I have tested this system thoroughly. IT WORKS GREAT! and not too complex either...

Yes, I mounted it in the cradle below the RWP as shown in the picture. I used the original alternator. I think I used 6 AWG wire from the distributor. You need to make sure you have enough resistance in the wire from the alternator. you may need to use a smaller gauge wire than I did from the alternator depending on how far the alternator is from the battery. I would suggest giving Mike a call at Hellroaring and tell him what you are doing and how far your run is from the alternator. He was very helpful when I set mine up.You should be able to get a hold of him today or just leave him a message and he'll call you back. I would run everything by him first, just to make sure you have it right before you start.

Don't cheap out on your cables or connectors! Remember, the system is only as reliable as the connections. I used the highest quality cables I could find and soldered all the terminals to the wires and used shrink tube.

I put the second battery under the helm behind the kick panel. I have the battery, 5 channel amp, XM receiver, Ipod controller, and a couple breaker switches under there. If you want, I will post some pics, I have it apart right now installing the XM receiver I mentioned. I had an old XM Roady, one of the original XM radio's, that I canceled five years ago but continued to work for free up until this spring.

here's some pics from when I did it.



I built a sub box to fit under the passengers seat. I wish I could have found a better place to put it, but I knew I needed the room under the helm for the battery and amp I figured they would be better off up there since there is no activity back there and it stays nice and dry. The sub doesn't get in the way too bad here, I can still access under the bow seating.




While were at it, here is one of the 6.5 polk db's


and the Hellroaring unit...



And, a close up of my knob. Just because I know everyone here likes to look at my knob!

akabulla,

Thanks, Just finished adding the XM and iPod adapter for the head unit today. Now I can control everything from the head unit.

I can't remember all the details of the install but everything works perfect. I used it a lot last year, no trouble. Checked all the cables for excessive heat, all is good. The amp is wired directly to the aux. battery. I don't see how it could draw off of the alternator.

Like I said before, I gave Mike from Hellroring a call before I started and ran through all my plans, I did a drawing of everything and scanned it then emailed it to him and he gave me feedback and I adjusted the plans as he recommended. I have a pretty good understanding of electrical circuits, but Mike deals with this everyday, so he knows what he's talking about. I would really recommend giving him a call before you start.

I have a pdf of the instructions that came with it, if you want, send me an email and I'll send them to you. you definitely want to have a solid plan before you start.

Take you time and do it right. Good luck

Matt, check your email...

Thanks again Randy. Greatly appreciated. I'll keep you guys posted if/when I decide to take this on.
