No spark Im not sure what I am doing wrong. But I can't get my A to run. It's recently been reassembled. I've triple checked the wiring and I believe it to all be correct.
It turns over. I have 6.34 volts on both sides of the coil and junction box. I have 6.34 volts on the end of the armored wire when the ignition switch is on. when I screw that back in, Only 2 to 3 turns, i get 6.34 volts at the points arm. Whether they are open or closed. What the heck is going on here. Shouldn't it show no voltage when the points close? Do I have a ground problem? I'm unsure of what to try next? I'm about ready to hire a professional. I just want it to work! |
Re: No spark yes when the points are closed and the key is on you should lose voltage at the dist side of the coil as well as the rest of that circuit.. do you have dirty points or a bad dist plate ground to the block?? take a jumper lead connect it to the moveable point arm,,,when you touch the other end of that lead to a good ground the coil should throw a spark and you should lose voltage back to the dist side of the coil...
if so it is a point contact or ground issue.. you can also try shorting it across with a screw roger;) |

Re: No spark are you losing the power at the dist side of the coil when you ground the points
the batt side of the coil should keep a constant 6v |

Re: No spark try the jumper wire method connected to the moveable point arm and to a head nut, key on do you lose the 6v at the dist side of the coil?

Place one lead of your meter on the points block and the other on the distributor upper plate. With the points open do you have a voltage? Yes it's not a ground problem. With the points closed do you have a voltage? Yes then you have a points problem. They are not making contact when closing. |

Re: No spark Key ON and points OPEN, then short across the contacts of the points with a screwdriver while holding the coil wire 1/4" from a head nut. You should see a hot blue spark each time the screwdriver is removed from shorting the contacts.
If not run a jumper wire from the condenser ground strap to a head nut or other good ground, then try the same thing again. |

Re: No spark tom he doesnt see anything but says he has 6 v there

Re: No spark It seems you do not have 6 volts at the points, or if you do show 6 volts, the connection is so poor that it can't carry the current to run the coil.
If you have a fuse, jump across it so you don't blow it out, then connect a jumper wire to ground and touch the movable open points arm to see if you get a spark. If not then touch the jumper to each coil terminal to see if you get a spark. Just strike the wire across the terminal or points to check for a spark. What was worked on since you last had a good spark? Any chance the key was left on and burned out the coil? |
Re: No spark I don't think I actually have any power at the points. I think I was doing something wrong with that earlier.
|
Re: No spark I do have power out of the wire that screws into the distributor and I will check the wire between that and the top plate after I get done with dinner.
