I agree with the previous posters that advised to check your polarity on the cable. I have four Deltran Battery Tenders on bikes right now with two of them being Juniors. They take a beating getting kicked around the garage floor and work fine.

i have six battery tender jrs. brought at the same time, all are under four years old. two have went bad in the last two weeks. one on my suburban in my garage and one on my sons new camaro parked in the garage next door has went bad. both are doing the same thing, blinking very fast green. one of them has been moved around quite a bit. the one on my bike is still good. all others seem to be fine for now. most are plugged in whenever the batteries are not being used. never been wet or even in a humid place or dropped. maybe these new ones are not as good as the older ones. if i have to buy new ones i'm going with something better. suggestions ? house wiring is fine along with garage wiring and outlets are wired correctly.

yes i've seen that, i talked to deltran and they told me to plug them in and i told them they continue to flash green . they said they are bad. even put my multimeter on them. dead. eight bucks a tender to ship back to them which i will most likely do. still if i have to buy any new maintainers i don't know if i'll be going back to these.

GREEN FLASHING - When the green light is flashing, and the red light is on, the battery is greater than 80% charged and may be removed from the charger and used if necessary. Leave the battery on charge until the green light is solid whenever possible. Once the green light begins to flash, it will remain flashing until the battery charger output current drops below the optimum recharge threshold, or until the absorption timer expires.

I have heard good reports on the Optimate 3 so I pick one up when I found a need for another tender. Among it's recovery and maintenance features I like the idea that it automatically runs tests on a regular basis while maintaining. It is a little more expensive than a regular tender but I think it makes a good addition to the 2 tenders I have. I plan on rotating them between my car, truck and bike every few weeks to allow the Optimate to run through it's cycles.
I found my Honda branded Optimate 3 at the local Honda dealer, the Harley doesn't mind.
