Forgive my ignorance... I made a Y jumper with a 1.5v battery. I touched one side and then the other and nothing happens. The only time I can get the driver to jump is with two wires. One wire on negative battery side and one on positive side of battery. I can then touch them to both terminals on the driver and it will jump. Switch the terminal connections and leave the battery side the same and it will still jump. I don't get it.
All drivers have some way to mark the positive terminal. It is essential to know which terminals are positive when attaching the crossover leads.
Usually these terminals are male quick disconnects as in the picture. There may be a + sign nearby the male terminal (look with a flashlight as it might not stand out well), a dot of red marker or paint, or different widths of the male terminal, where the larger one is positive. Often, but not always, the negative terminal is not marked.
To test with a 1.5 volt AA battery:
- Attach two short pieces of wire, about 5" or 6" long, to each end of the battery with tape. Attach one wire to the positive end of the battery, and the other wire to the negative end.
- Hold the wire from the negative end of the battery against one of the two driver terminals.
- Touch the wire from the positive end of the battery to the other terminal.
- If the driver cone moves forward, you have the positive end of the battery connected to the positive terminal of the driver. Mark it so you can easily see it. I use a dot of red nail polish.
- If the driver cone moves backward, you have the positive end of the battery connected to the negative terminal of the driver.
