richiec Posted June 9, 2009 Share Posted June 9, 2009 hi all im in a bit of a pickle with the wiring on my dt125 im new to bikes so some questions are going to be stupid. here we go 1.what voltage will this bike run on im asuming its a 12 volt system. 2.none of the electrics on the bike work the bike runs but no lights or clocks etc ive been told the rectifier has gone. 3.i havent got any voltage across the battery even with the bike running. thanks in advance richie Link to comment Share on other sites More sharing options...
wild foamy Posted June 9, 2009 Share Posted June 9, 2009 take out the bulbs and check to see if they are 6 or 12v, its not a foolproof way of telling what voltage it is but if the majority are 6v then its probably a 6v system. what year is the bike? if you arent getting any output from the mag then this may be down to the reg/rec unit, check for an input voltage to this unit Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 9, 2009 Moderator Share Posted June 9, 2009 Hi richie, not familiar with the bike but isnt it an elec start one? It will be 12V. If you arent getting any voltage measured across the battery then the battery will be an Ex battery, youre gonna need a new one and take it from there.

richiec Posted June 9, 2009 Author Share Posted June 9, 2009 thanks for the quick reply guys will check everything tomorrow now and report back oldgitonabike its a kick start bike no fancy electric start here lol Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 9, 2009 Moderator Share Posted June 9, 2009 thanks for the quick reply guys will check everything tomorrow now and report back oldgitonabike its a kick start bike no fancy electric start here lol Ok if its an old style battery, count the filling plugs 6=12v and 3=6v Link to comment Share on other sites More sharing options...
wild foamy Posted June 9, 2009 Share Posted June 9, 2009 surely he would be getting a charging output even if it was a dead battery?, only when the bike is turned off the battery would not hold its charge Link to comment Share on other sites More sharing options...
richiec Posted June 9, 2009 Author Share Posted June 9, 2009 abit confused now just checked the bulbs the only one with a rating was the front sidelight bulb which was 12v i have also taken the battery off and it has 3 cells and the following number on it 6n6-3b-1 if that helps Link to comment Share on other sites More sharing options...
wild foamy Posted June 9, 2009 Share Posted June 9, 2009 its a 6V Battery Link to comment Share on other sites More sharing options...
Moderator Airhead Posted June 9, 2009 Moderator Share Posted June 9, 2009 its a 6V Battery Yep...I think that rich knows this...and the bulb with 12v on it is 12volts... Link to comment Share on other sites More sharing options...
wild foamy Posted June 9, 2009 Share Posted June 9, 2009 Yep...I think that rich knows this...and the bulb with 12v on it is 12volts... but the battery is 6v, so the bulb will only be recieving 6v not 12v, thus it is twice as big as it needs to be and will be half as bright. well actually, taking into account ohms law it wont be EXACTLY half as bright, but you get the general idea Link to comment Share on other sites More sharing options...
richiec Posted June 9, 2009 Author Share Posted June 9, 2009 so its a 6 volt bike with the wrong bulbs lol next step i supose is replacing the battery and getting the correct bulbs and going from there cheers richie Link to comment Share on other sites More sharing options...
