Here is a partial battery check circuit from Tesoro Bandito. Don't know how similar yours is, but here a shorted capacitor C7 could cause the tone to stay on. -
hi, thanks for your reply i will try that capacitor.Comment

hi, i have replaced capacitor in battery check circuit but machine still continues to have constant tone. this circuit in the laser b1 has a nasty little hybrid board with surface mount ics the only part that is not surface mount is the power supply i have asked my friend what did he do to it he said he connected a 10 amp power supply to it. i have found that the 7808 positive regulator was fried so i replaced that and now have the correct voltages to the rest of the circuitry but still continues to have the batt check tone i think theres a ic down. any help would be much appreciated thanks jay.Comment
