So here's what I have going on wiring a coil to a toggle switch I have 12v coming to my switch and from the switch to a .85 Ohm resistor to the + on the coil and from + on the coil to the distributor (points type) coil is an external ballast pn#1303 I'm getting from + to - on the coil 1.7 ohms from the 200 Ohm setting on the multimeter then from the + to the coil output on the 20k setting I get 9.08 at the resistor I have 12v in and 5.6 out with that being said I'm not getting any spark from the distributor
Here's a good introduction to basics points type ignition systems... https://www.jalopyjournal.com/forum/threads/hot-rod-technical-library-basic-ignition-systems.983424/ If the car is a negative ground system, the negative lead from the coil connects to the distributor.
The - on the coil should go to the distributor. If the above is not a typo, then I've found your problem.
It is a confusing read and I was leaning toward the same thought. However I think OP is referring to plus into resistor and plus out from it to the coil ?
Correct, slight typo my apologies I was rushing trying to get it all written out and I know it's written very confusingly I'll get some pictures later this afternoon and post them so you guys can see what I'm working with and hopefully point out a simple fix
My apologies for not getting back quicker but here's a picture of what's going on: battery to switch, switch to resistor, resistor to coil +, coil - to distributor (points and condensor)
Here's a quick and dirty check. Disconnect the - wire from the coil (going to dist). Hook a jumper from the coil - and intermittently tap it to ground (just tap quickly). If you get spark from coil, then check distributor out. Look for bad points, condenser, cracked cap, carbon button in cap, rotor, etc.
