Redarc isolator

Yep, close to the battery, sitting upright, on top of the wheel arch. I utilised an existing bolt negating the need to drill into any bodywork. I have found that one good bolt is more than enough to mount the isolator effectively. I have done this on two vehicles now.

Fit it close to which battery? The main point is to mount it in a position so that the lead between the two batteries is as short as conveniently possible.

My Redarc isolator is in its second vehicle now.First one it was mounted exactally half way between batteries and this time its mounted close to the aux battery.Wored the same on each.

The reason you want it close to the battery - starting not the aux - is the longer the cable the more chance of voltage drop ,ergo the Redarc may not cut/out in at the specified voltage , that said ,really does not make much difference as long as the cables are of sufficient thickness and lugs are crimped properly.

This is where my Redarc is in 2007 D4D
