Hang up the battery between measured and (5), 7 (4) the feet have voltage, along the line detection chip insurance tube (3.15 A) has no voltage at one end. 3.15 A insurance has been open. As the impact analysis may be electricity instantaneous over-current fuse. Try on average 3.5 A insurance on both ends of the pipe welding wire connection on both ends of the original 3.15 A haven, after be tested with 3.15 A output end. No short circuit phenomenon. The electricity of commissioning, the power light is lit. Continuous commissioning five minutes without exception, judge the fault has been ruled out. Lvgservice manual download site
