dual battery problem

[v6 prado Lurker Find all posts View Profile Close v6 prado]

gday, having trouble with my VSR100 led light not turning off after doing test with headlights on so the switch would turn off. Have had same setup in my old suzuki vitara with same Aux yellow top and worked fine, but now having charging issue in 120 series. Not sure if the VSR has finally givin up the ghost or something else. Im not new to dual battery setups but this has got me stuffed. Am using my solar panels that i have mounted to the roof for charging AUX battery. Thinking maybe the batteries arnt compatible but didnt seem to worry the vitara. My in-paralell switch works so there is power getting to it. Have done multipul voltage checks, the alternator is working maybe starter just not charging enough to activate VSR. Now i know that the projecta's arnt that expensive but it has worked for awhile now without any prob. these picks are of what i have and the config of sorts, hope the pics worked cause im new to this stuff. Any suggestions.,

cheers

I had a VSR die but mine wouldn't charge the battery so I wrecked a battery. So they do fail.

Start car what voltage do you get going into the isolator?

Is the isolator properly earthed?

What voltage do you get on the output side with respect to the cranking battery negative terminal?

What voltage are you getting across the aux terminals?

thanks guys, im getting 14.12v going into the main connection of isolator so there is definatley power comming from starter to VSR but nothing going out off vsr to aux bat, voltage at Aux is about 12.8 but drops slowly, not sure what you mean about out put side of crank

just an update, the Isolator started working again, (dont know how), starts and stops so it is definatley the VSR. contacted projecta and they are sending me out another one for free. I took the Isolator off checked it over rechecked the wiring went over the whole setup and no problem there. When i get more $$$ im going to get a redarc i think.

update on vsr problem, just recieved my new projecta isolator and it works fine now, so it was the older isolator not any connections or anything which i already knew.
