Phoenix Gold Phorum

Just noticed this today...only one of my 4 TiZBB12 Voltage Monitoring LED light turns on and the other 3 are not. But, all Fuse Status LEDs lights on all 4 TiZBB12 fuse blocks does come on. See pics...can anyone tell me why or how to de-snag this. Find it hard to believe that the LED on 3 blocks would be burnt out. See pics.

I'd need to look in the manual but isn't there a switch inside that does something?

Yes there's a switch and that switch turns on all LED's including the Voltage Monitoring LED. And the switch is at "ON" on all 4 blocks.

I agree, hard to believe but not impossible. Only way to know for sure is to test for power. Or put them under load because these should be the multi color LEDs. If they go under load and they light up orange or red then the green filament is bad.

it has been a while for those for me, but in the manual there you see there a ground and remote 10gauge connection.....

could it been wrong connected by mistake ?? check that out one time.....

for the rest you're gonna need a dmm to measure out.............

indeed 3 units that have a blown led would be much at the same time.............

If all four are the same then why not compare voltages from the working unit to those not working? Start by checking the voltage of the LED, perhaps the LED did go out after all they do have a life span you know.
