View Full Version : Big thanks to Diesel and Sodar!

Did the dual battery install with Borg Warner relay as described by Diesel in the Official Dual Battery Thread. And went the extra mile by following Sodar's idea to mount the battery forward of the driver footwell. It was a pain to get it in there but better than taking up accessible space under the observer seat. Thanks guys for the great ideas and guidance.

I think I get OCD style points for using a billet aluminum battery holder for the Optima Blue top and Streetwires terminations in a place where NO ONE will see them (truth be told, I had the billet and Streetwires stuff laying around).

Why not post a picture of the install, so we all can have a look!

Pics now or I'm just gonna sit here and wait

Sorry about the delay. . . darn work! I'll get some pix tonight--hopefully good enough to see the important bits (with all that wiring in the way). Thanks for being patient.:)

Glad it all worked out for you. Hopefully you put in some good batteries and maintain them regularly, so you will not need to get them in or out of that spot for a few years! :)

Let's see some pictures. I never really looked into Diesel's Borg Warner unit, so I would like to see the completed project.

+1 - nice story - didn't happen... ;)

has anyone heard from diesel in a while? never see him on here anymore.

02-04-2013, 06:40 PM
He hasn't logged on in over a year.

Okay guys--I'm not an expert at this so bear with me. Also, shooting photos under the dash with all the spaghetti made for some tricky lighting.

First, modified the batter cover a la Sodar's install:

Then, ran custom terminated wiring (did my own but I have a tool just for compressing lugs onto cable--2 Gauge in this case.

Here's one part of the install that I could use some other ideas on. Currently, the wires to the House Batt/Isolator run forward from the starting battery and then through the cutout for the heater duct. I did sleeve the cable in plastic loom so that the fiberglass edge of the heater access cutouts won't damage the softer insulation on the cable. Any ideas of alternate routes?

At any rate, here's the isolator as suggested by Diesel--mounted on the bulkhead near the other electrical bus bars. Positive in/out secured with nylocks. Signal cable tied to the ignition key and ground for relay activation:


And finally, the overkill billet holder and streetwire clamp (ground side shown). A bear to get it in there and I will be adding a battery maintainer for just this unit--taking Sodar's sage advice so that I don't have to wrestle that thing much:

okay - that's a nice project...well done!

02-04-2013, 08:28 PM
Very nice job.

Nice post.

Looks good. There is a chase from the battery box, under the floor and then over to the dash if you want to get the aux battery cables hidden.

Thanks Sodar. I see the original cables from the batt to the dash bus bars going into a chase but could not figure out how to fish it through. I need to give that another go when I'm more patient--I know it will look neater!

use a fish tape or coathanger. Make take a few tries. Fish tapes are cheap for short ones and well worth the $ if you are going to work on the boat yourself.
