Trik l start

Had one hooked up for several years, so worked.  Alarm started beeping several days ago, low battery light on.  Group 65 bat exactly 3 years old.  Put on battery charger at 15 amps for 7 hours.  Status indicates never got over 80%.  Just today installed brand new battery dated 3/23,  vmeter shows 12.89 volts.  Low battery alarms starts again.  Crank truck and charging/maintaining light comes on, shows 14.3v on scan gauge,  run 15 min, turn off , alarm again.  Unit has been plugged into 30 amp for 3 days.  So do I need to hook up the charger again?  Seems like 12.89 should be plenty adequate .  Book says should alarm at around 11.5volts?

Hooked up charger again for 30 min @15amp.  Status at 100%.  Still alarms.  Now disconnected ground on trik l start, just to shut off alarm.??

Op again.  Took a 6 mile loop to throw some boost into the crank batt.  Scan gauge showed 14+V from alt.  Check batt when got back, 12.8v.  Triklstart does show yellow/green when engine running.
Plugged back in to 30 amp.  2 6v Napa gold house shows 13.4 when plugged in to 30amp shore.  Just like that, alarm stopped, showed green, ok!  Slammed driver door and started beeping again.  Took everything wiring wise apart and no loose connections? 3 page posting about triklstart 3 years ago, what got me started with one.

Sounds like a misbehaving alarm circuit. You may be able to shut it off. However, in my opinion I would want to know what is feeding the alarm circuit and find the problem point and fix that before it affects any other functions.
