well, went back out to the garage and connected the voltmeter to the black and white wires. when i kick it over it reads 6 volts or so depending on how hard i kick. i don't know if it is unreasonable to think that if the stator is putting out voltage the coil should spark unless it is bad or the stator is not putting out enough volts? how many volts should the stator be putting out when i kick this thing over?

thankyou. i will try that this morning and get back to you.

well got those #'s off the neck, i still believe it is a dt250. the #'s are DT1F-25264. the sticker says 1970. someone told me to see if there was any current being produced from the stator so i started playing with the bike. i set my voltmeter to AC volts and connected it to the yellow and black wire then kicked it over. the reading was coming in at max of 9 or less volts depending on how hard i kicked. how much should the reading be? i also connected a know good coil to the bike but still no spark. do these bikes require a battery to start them?

hi and thankyou for replying, i think i will try that. i will go over to the kids house and take some pics later this afternoon.

Hey everybody, i am new to this board and joined because i need alittle help from the dirt bike gurus. i am a chopper enthusiast and am trying to help a neighborhood kid who came to me looking for help. he saw that i work on bikes in my garage and stopped to ask if i could fix a dirtbike he found. i believe the bike is a late 60's to early 70's yamaha dt250? he found the bike abandoned in a field close to his home. it had been sitting there for years but the frame and engine where still there, everything else people took off. there were still some wires connected from the engine to the coil. my question is if anybody could help me figure out how to connect the wiring so i can try to start the bike. i have found some wiring diagrams online but they are stock. i would just like the simplest way to connect it so the bike will turn on, i am not worried about lights or anything like that. i will try to attach a drawing of how the bikes wires are connected when we found it. any help would be greatly appreciated as i want to get the kid enthusiastic about bikes, it's a great hobby!! thanks fellas, Lou
