... Each relay worked perfectly for ~3 months before 'shorting').I installed the relay in order get 'between' the heated-grips wired directly to the battery (because of heavy current draw and has a separate control panel that must be remembered to turn OFF) and the ignition switch (thinking: no more ruined batteries for me!); and also to delay the headlight from blasting ON until ~10sec after starting.
The totally depleted batteries would not take any charge from either of 2 different chargers.
I attributed this 'quirk' to the unique nature of the battery and something we would all have to live with.
I was under the impression that an AGM totally drawn-down was ruined......
I recently found this article and possibly a remedy to my not being able to get any of the 3 AGM's to take a charge and necessitated a purchase new.
I haven't had the opportunity to try this yet; but it sounds extremely reasonable to me.
