Trickle charger update

Several readers have written to address a glaring omission in my last column regarding trickle chargers and 12-volt positive-ground motorcycles. Specifically, the bare lead of the pigtail will be the hot lead and must be prevented at all times from contacting the frame or you will short the battery to ground with no fuse to stop you. I don’t know how I missed this, but thanks to everyone who wrote to point this out; it’s important.
