100 series battery isolator-best location?

Hi Nootsa,

I installed a Redark dual battery system into my 2003 100 series. Iguess the Projecta would be similar.

I made my own battery tray as it was way cheaper than those comercial ones and it is a made of better material as well.

I had to relocate the overflow bottle and place it closer to the front of the vehicle on the radiator support panel. This left enpough space for the N 70 battery.

I made up a new tray out of 3mm gal and created the standoffs (2 of) and welded them to the underside of the battery tray. Keep the tray as low as you can. At the bolt nearest the air cleaner the tray is sitting on the inner guard.

There is a small electrical device, not sure what it does but it looks like a voltage regulator, and I had to relocate this to a point closer to the firewall but on the same RH side wall. It was at point A in the pic and was relocated to point B onto a bracket I made for that purpose.

The dual battery cutout solenoid was fitted into the sapce between the new battery and the aircleaner but on the side wall, see pic.



Mount the battery tray first then fit the battery and see where you can best locate the solenoid in the area I mentioned. If I recall correctly I used one existing hole and used a self drilling TEK screw for the second mounting bolt.

If you need more info just ask.

Hope this helps.

Cheers, Bruce.

I have mine mounted on the passenger side guard just behind the fuse box and in front of fuel filter on the horizontal area
My cruiser is 2005 live front axle with a N/A deisel

Plenty of room on inner guard behind second battery on passenger side. No need to relocate anything.
