i own 2001 rancher 350 es and 2004 trx 450r. my in laws own 2 2004 rancher 350 es's. nice to find a site like this, whish i new sooner. but the problem i'm having now is with one of the 04 ranchers. battery was low enough not to start quad and shifter wouldn't work. got it chraged enough to get on trailer and get to my place. charged and drove. shifting only would work would you kept rpms up a little. ran fine but then it just bogged and stopped shifting . battery would not take a charged so i replaced. now it starts fine, shifts fine, idles fine but you cant give it and throttle without it missing and cutting out bad. did i wreck something electrical by driving it low on voltage? right now running it is charging @ 14 volts +/_ .5 volts. any guidance would be apprecciated.
