Help with Timing Light

[Randyg123]

It's been about twenty-five years since I used a timing light. Now I find myself needing to use one on my outboard.

I acquired a timing light a few years back when I inherited this old boat and now need to put it to use. It is an old Snap-On MT-215. The power cable has two aligator clips are both black. I cannot see any indictations which is + and which is -.

Is it possible that the leads can be connected in either battery terminal

The black one goes on (-), and the other one goes on (+).

sorry, couldn't resist.

you got it - the light bulb doesn't care which direction the electrons are going.

I have a old Snao On light and it is not polarity sensitive

Electrons are funny that way
