How guys
Some advice needed from the group does this sound like an Alternator needing replacing or somthing else?
I'm getting my redarc SB12 clicking out when the car is crawling around 4wding in the last few months thinking not much of it until my trip it was getting worse when ever I stopped for a min to two clicking out then in when I moved off
Yesterday I did some testing
Battery main 12.7v cold no start and rear battery 12.6v cold no start all good there
I have the diode from Leigh installed
Time to start car with multimeter on main battery and 14.2v all good and rear battery 13.8v.I let it warm up 10mins and 14.1v happy with that, I then placed load on it with headlights front and rear aircon on still 14.1v that's good
So test on road time driving around 14.1 14.00v OK happy again
Next I pull up to a stop and 13.9v I think turn on air con and lights and this is what happens watching volt reading in cabin it starts to drop right down to 12.8 then I hear redarc click out and I read 12.5v.I then put the car into park and volts rise back to 14v with lights air conditioner on OK strange.i head home and in garage with car hot at about 90c when all this happens I then test again same results this time in drive I held the brake and slowly increased the revs and it goes from 12.5 up to 14.1v with revs around 800rpm to 1000rpm ????? The car in drive sits at about 550rpm
My Prado has just ticked over 200,000kms V6 been great till now I'm thinking it's the original alternator is or has failed no dash light on and tried with duel battery connected and not no change
Any advice and if I just replace it what brand to go with
Thanks
Ben
