Mx-05 6-volt regulator

Can I assume this mx-05 has failed.

I have my mx-05 6-volt regulator connected between a 12volt battery and the wiring harness and my ssc32. This morning when i turned on the power, the ssc32 green light momentarily lit and then I heard a click on the ssc and the green light went off.
I tried a couple times and same result each time.

ssc32 operates normally from the wall 6v power supply

Should I rebuy the same regulator or can someone suggest an alternative. $ 20.00 seems alot for these regulators

The website clearly states “8.4vdc max input.” :frowning:
