Guess I need a multimeter after all. I will try to solve these final two puzzle pieces and report on progress (may be awhile). Thanks loads!
Here’s a pic of the manual from Mammoth…
Sir, you are a modern day hero.
I kept meaning to learn how to use a multimeter and I’ve had the project on my shelf for a year now. Bless you.
I’m looking at the Mammoth instructions, and I still can’t figure out where to connect these two things (from the Mammoth PCB):
– the positive tip of the LED
– 9v source
Any thoughts?
