ORIENTATION OF ISOLATOR ON BENCHMARK STAGE 3 DUAL BATTERY KIT

This is my first post. This forum has been a treasure trove of information.

I purchased a 2010 4 door JK Wrangler.

I need some advice as to the orientation of the isolator in relationship to the BenchMark Dual Battery set-up.

I am installing the BenchMark Design Stage 3 Dual Battery Kit using Sears Platinum PM-2 deep cycle marine batteries. The batteries are in and fit with little room to spare. The engine is now running but only wired for a single battery.

I AM CONFUSED AS THE THE ORIENTATION OF THE ISOLATOR IN ITS RELATIONSHIP TO THE "MAIN" AND "DUAL" BATTERIES.

It easiest to make the engine side battery my "main battery" for attaching the OEM battery wiring. This then makes the passenger side battery my "auxilliary" battery. John from Benchmark also suggested this same arrangement for the batteries.

Please look at the instructions that John sent me.
https://docs.google.com/viewer?a=v&p...c9Q7iphQ&pli=1
The isolator with the 3 wire pigtail is pointed towards the firewall of the vehicle. This orientation has the labels on the isolator showing the "main" as being passenger side and the "auxilliary" as being engine side of the vehicle. This would seem to be wrong for this battery orientation.

Please look at this photo of the isolator on the dual battery.
http://www.flickr.com/photos/donpatt...n/photostream/
With the 3 wire pigtail pointed towards the front of the vehicle, please notice that the labels on the isolator now show the "main" as being engine side and the "auxilliary" as being passenger side of the vehicle. This would appear to be correct for this battery installation. However, this is the exact opposite orientation of the attachment that John sent me.

I tried calling John but keep getting his answering machine. He did respond via email suggesting pigtail towards the firewall but with no explanation as to why this does not match the labeling on the isolator that he sent with the kit.

Any recommendations would be greatly appreciated. I just want to confirm what has worked for others before doing the final hook up.


Thanks you.

Ron Liljedahl

Mine is wired/mounted the same, and my pigtail is facing the firewall... I just had to put a small bit of tension on the wire running from the battery to the isolator.

You will have to rotate the positive terminal of the aux battery 180* so that it is going toward the engine and not the body. (Top left of your pic)

JOHN

WHAT DOES "CORRECT" MEAN?

I AM SORRY TO BE SUCH A PAIN IN THE XXX BUT YOU NEED TO EXPLAIN THIS SO IT MAKES SENSE.

One response here "has his pigtail towards the firewall" and the other response has his "pigtail towards the front of the vehicle".

I CAN NOT BELIEVE THAT IT DOES NOT MATTER HOW THE ISOLATOR IS ORIENTED IN ITS RELATIONSHIP TO THE MAIN BATTERY?

MY MAIN BATTERY IS TOWARDS THE ENGINE. WHAT WOULD BE THE CORRECT ISOLATOR ORIENTATION?

Thanks for your response with the picture. I still do not know how to post a pics.

Please confirm that your main battery is positioned towards the engine.

If so, your orientation of the isolator is the exact opposite of the directions and pictures that were provided to me by John of Benchmark Design. I DO BELIEVE THAT YOUR ORIENTATION IS CORRECT AS IT MATCHES THE LABELS ON THE ISOLATOR.

Thanks again.

Thanks for your response.

Please confirm if your main battery is positioned towards the engine.

If so, it matches the directions and pictures that were provided to me by John of Benchmark Design. This orientation would be the opposite of what the labels on the back of the isolator suggest.

Thanks again.

No problem, in my picture - my main battery is on engine side not fender side, on the smarty isolator it is also labeled which connection need to go which way, the pigtail in the picture is the correct way to the orientation of my batteries are set up

If your batteries were switched , then the orientation of the pigtail would be in reverse

John suggested that I make the engine side battery my main but then sent me a picture with the pigtail pointed towards the firewall. That orientation did not make sense when I read the labels on the back of the isolator.

I would be interested in seeing which battery ZJR is using as his main as his pigtails point towards the firewall.

I have emailed John several times but my email is screwed up and I am not getting all of it these days. I do not know if he is ignoring me or I am not getting his reponse.

I am "electrically challenged" and need all the help that I can get!

Thanks.

I do have one more question.

Go to page 2 of this pdf file that John sent me.

https://docs.google.com/viewer?a=v&p...c9Q7iphQ&pli=1

I am doing a "Stage 3 install" and do not know if I need to do the"Stage 2" install that is at the top of the page.

If I must do the "Stage 2 Install" I do not understand steps 1, 2, 3 where he describes the "chassis end of the harness and the isolator end of the harness with the red and black wires".

Thanks.

Ron this is the exact orientation. Aux battery is on the left, main is on the right (near the engine).
