Hi,
A bit of a dumb question sorry.
I was just wandering if it would be safe to jump start the car using the dual battery.
Should I remove the dual battery first or what ?
I believe some isolators have these capabilities built in but not sure if
mine has.
Richard

Richard, Jump-starting through your Redarc isolator can be dodgy unless it has been installed with sufficiently heavy cables and you know what you are doing. I know the technique is offered in the Redarc instructions and that others do it, but......?
I DO know what I am doing and my cables ARE starter sized, but I still would rather not put starter current through my Redarc solenoid.
Seems to me that jump-starting should be a rare event anyway and it is hardly much trouble to simply use jump-cables from battery to battery as you would normally do. If you want to be extra careful, disconnect the existing negative terminal from the auxiliary battery before connecting the jump-cables, but the battery can remain in the vehicle.
Having the Redarc set up for jump-starting does NOT dispense with the need to carry jump-leads. You never know when you may need to jump-start from or to another vehicle.
