wild foamy Posted February 25, 2009 Share Posted February 25, 2009 could be that the battery acid was mixed incorrectly causing it to loose its charge or there is something else left on which drains the battery. it doesnt take much to kill those little batteries, e.g. if your brake light switch is loose and the brake light is left on it will flatten the battery within the space of about 5-10 minutes after leaving it for an hour, check the voltage in the battery using a multimeter, then start it and check the voltage again (should be about 14v with the engine running) to make sure it is getting a charge Link to comment Share on other sites More sharing options...
