Why am I only getting 6 volts going to my coil???
 

84 302 F150 auto 4x4 carb and dura-spark

the leads to the coil only have six volts when starting
truck stoped running so I don't what I have for running voltage

took the box to autozone and it tested good twice :-X03

going to try the connections tomorrow
does anyone know who sells the plugs to connect the ignition box to the harness???? pn????

my car blew up the day after I bought this truck so I NEED it to run!!!! :'(
good news is I bought a $300 truck and the 4wheel drive works!!

With the key on, see if there is a voltage drop between the distributor body and the battery negative post. Also, if you just need to get it running, splice the wires with suitcase connectors (aka tap splices, Scotch Locks). You don't have to cut off the connectors, and you can pull the splices back off later when you fix the plugs.

just to make sure we are on the same page can you give me a play by play on looking for that voltage drop?????

6V is completley normal for a coul during cranking, esp if your using a Digital Voltmeter. there is a constant fluctuation of 12V to 0 V then back to 12V and this happens very rapidly. why?

ignition coils basically make power. the 12v is used to create a small magnetic field around a winding of coil. once the power is cut off from that magnetic field, that magnetic field collaspes into the coil, creating an intense spark. that spark is then sent to the dist ad down to a spark plug. it must do this rapidly to be able to provide a spark for each cylinder at x-amount of RPMs.. the igntition module on electronic systems controls the speed of the power to the coil. pre-electronic systems, a point (or basically a switch) did this contant on-off power to the coil. there was a "bump" for everey cylinder on a small rotating cam inside the distributor. these bumps would kick off the point, turning off the coil and creating the spark. each bump was aligned with a cylinder.

anyway enough lefture, 6V at the coil during cranking is normal. due to the consant fluctuation of 0-12V.. and whats in between 0 and 12V? 6V.. Digital Voltmeters read the average voltage when theres a constant fluctuation. if you were to try an analog meter, you might be able to notice the flickering.
