I made sure everything was connected (kill switch, cdi coil ) and still no spark. i hooked a battery up to the red power wire on the CDI and when i did the voltage at the wire going to the coil slowly climes from 0 to about 7.v at about a rate of .01 volts at a time then when it hits 7 volts it drops right back down to about .5 then slowly starts climbing again??? i have no idea whats going . how can i test if the coil is faulty? what should i do!

how much do you want for the cdi and the pulsar coil?

i have a 1978 DT400 i just picked up , wiring is all messed. i got a wiring diargram from a fellow member but im stumped, im not going to use any lights or anything, so what are the basic things that need to be hooked up for it to run without a battery? or run at all for that matter.

Thanks for the wiring diagram Paul! but im stumped, im not going to use any lights or anything, so what are the basic things that need to be hooked up for it to run without a battery? or run at all for that matter.

Hey guys, new to this forum. im hoping you can help me! Today i purchased a 78' dt 400 not running. alot of the wires are not connected in places, and im not familiar with the way dirtbikes work. i dont need the lights and horn/ signals to work all i want to do is get the bike running. there are two small aluminum boxes under the seat which have wires comming out of them , what are they? do i just have to get power to the spark plug or do i need to use the ignition and starter kill switch? anybody know where i can find a wiring diagram? thanks for your help i greatly appreciate it!
