Has anyone used the Bus Depot "Leisure Battery Kit"?
http://www.busdepot.com/j15328
I know they have just the relay, but the kit has the battery terminals and all that. Great. Specifically I'm mostly wondering how long that positive battery cable is. Is it long enough to go from the starter battery all the way over to the left side of the engine bay? Or from the alternator to the left side of the bay? Or does anyone just have a measurement? I couldn't find that info on Bus Depot. I would assume that they made it "long enough" but I don't assume that they intend to put the house battery in the same place I do. For all I know, it's "supposed" to go inside, under the back seat or something. But I'd like to put mine on the left side, opposite the starter battery.
Thoughts?
If that cable isn't long enough, I'll just get the relay (below) and source cables and fuses from my FLAPS.

I am sorry if reviving a dead post.. and sorry again if I missed this, but is there a complete list of what to get to install a second battery and what it needed to then set it up to run 110 volts items? I get lost in all the posts....
thanks kindly in advance =]) |
Go back and read the first three lines on the first page . That's why I took all the photos and did this thread .
then plug in an inverter to run LIMITED 110 volts |
It would be great if anyone could see the photos in the first post. While I appreciate the thoughtful tutorial, the dead photo links make it useless. I really don't get why people don't use the samba gallery. I found this incredibly frustrating while restoring my 67. _________________ '67 13 Window

Hey all,
Reviving this old thread for a min... what great info. Quick question - what would be a suitable gauge wire to run from the 2nd battery up to an aux fuse box? The one I'm thinking of using has 6 circuits, much like the Blue Sea unit. I would run USB chargers, a few LED lights, maybe driving and an extra reverse light for better visibility. I read this article https://knowhow.napaonline.com/know-how-notes-automotive-wiring-guide/ and was thinking that a 2 gauge wire would be too big and 10 gauge too small. Is that accurate? I suppose it depends on the total current draw and distance but the bus only has a 55 amp alternator and I can't see more than maybe 20-30 amps coming from all the extra junk I'd like to install.
Thanks,

Hi Mike. I have a Blu Sea set up and used 4 Guage for that run. I have the 12 slot fuse box (6 switched and 6 constant). I have not had any problems.Good luck! _________________ All the redemption I can offer, girl, is beneath this dirty hood

Yes. Both batteries are fused as well. The driver's side aux battery has a separate body ground in the engine compartment. _________________ All the redemption I can offer, girl, is beneath this dirty hood

Cool, thanks. So - aux battery - one negative cable run up to the aux fuse box along with the positive and another ground cable to the body in the engine bay.
Got it,

Yes. I always benefit from seeing electrical drawings/schematics. If you are the same, here is a visual that should help. It was sent to me directly by Blue Sea.
