coil help needed

Can someone tell me how many volts DC you should have on the red wire on your coil. Mine is coming up with 7.3 volts DC, and I am not getting any spark to the spark plugs.

I have tried new brain and new coil. When I put the new coil on I got a spark at the plugs for a few seconds and then it quit sparking at the plugs.

what kind of ing. system you have will help to find the problem

Its all stock ignition.

I have 12vt. coming to the positive side. Check the negitive side of the coil and see if it has signal coming to it, it could be your pickup in the dizzy going out causing your spark to go away.Check the wires going to the whole system to make sure you don't have one almost broke or trying to ground out some where.
Maybe this will help

Thank you very much, I will check it out tonight. Their is some signal coming out of the negative side of the coil, not very much though. It will just barely light the test light.
