"The only negative for an old man like me is, like most new electronic test equipment, it is capable of giving me way more information than I can handle. Because of all the different modes and information that is available and the fact that I don't use it every other day, I have to get the instructions out every time I pull it out of the tool box."
But....the basic timing light is pretty simple. Induction pickup around #1 plug wire (Arrow to plug), green wire clipped to distributor for rpm/dwell reading and red/black power leads to a battery. Make sure it's in the 4-cycle mode and 6cyl. A 12v supply might give you a little stronger strobe light. So if you do have a spare 12v, set it next to the fender and power it off of that as Jerry pointed out earlier. But, it will fire off of the 6v also. I've not really found a need for the advance settings myself and generally setting the correct point gap put's the dwell in the ball park. Only use I'd have for that is to double check my gap or to check for any wear on the cam, which I've never seen in any distributor yet.
This is probably the best way to introduce you to your new timing light. Only takes a few minutes of your time:
