Yes, that's exactly the one. I bought one twenty years ago and it has saved me UNTOLD hours of misdiagnosing electrical problems on bikes and cars.
cannot fool one of those things. It might read 12.7 volts at rest all day long, and people say "Oh, it's good, I tested it with a voltmeter", and then it dies as soon as a 30-amp load is connected across it.
is one of the most fragile and failure-prone components on a motorcycle, but for some reason people think that they are unlikely to fail, that if they look good they must work good, if it is new or new-ish, it can't be bad, and that if a 12 volt battery
reads 12 volts it must be a good one, when in fact a battery
that reads 12 volts is as dead as Stonewall Jackson's horse.
I don't know how many times I've said "Load Test The battery
First", and folks don't do it, and a week later it turns out to be the battery
If you're doing your own work, GET ONE!
