Ok, I got the black beast home the other day and went out yesterday and today and bought a whole bunch of new ignition parts for her..put them all in and she still won't spark over. Replaced plugs, cap, rotor, battery, battery cables, starter solenoid, coil and plug wires. She will crank over but not spark. Any ideas would be appreciated.
Is the correct wire from the distributor hooked to the correct side of the coil? Verify which side is positive and negative. Pull a plug and put it on grounded part of frame, turn over motor and watch for spark to verify that you are in fact NOT getting spark.
that thing have electronic ignition(75 it should) or points??? could be the ingnition module is Kaput.(if its electronic)
It does have points and condenser which I didn't get to changing out yet. The fuel pump is currently not hooked up but did dump gas down the carb. Pulled the #1 wire off and didn't see a spark.
The new coil is marked + and - vs the original which was marked battery and distributor. I did hook them up on the new coil exactly as they were on the original one.
No electronic ignition, it's a 70' not a 75'..the 75' is the green beast which is the wifes. On the hood latch area it does have a sticker which reads "See Dee Ignition"
Do the points/condensor before any thing else.In case your still up in the air about wireing at the coil.Battery(Batt= + positive teminal) Negative(-) is where the wire from the dist goes. The wire on the positive side is from a switched ignition source(usually the ignition switch itself)Make sure you have power at that wire with the key on.If you do,get new points/condensor.If not,its time to chase that wire back to its source.Or you can run a jumper to the coil+ terminal from the battery and try to start the car.If it fires up,Good,shut it down and chase that bad wire back to the ignition switch.You dont want to power the coil off the battery for long.The stock coil isnt meant to take 12 volts.That wire is a resistor wire that lowers the voltage to the coil.If you buy a new coil for a later car or an aftermarket high perf coil,They can take 12 volts.Hope this helps,good luck.
The later factory TFI coils are great for the money and can take 12v, but they do not directly fit in place of the original coil as they look more like a transformer then a cannister, so you have to use a different bracket. Just tell the parts house you need a coil for a '89 F350 with a 460 if you decide to go to a later coil. I ran that one for quite a while on my '72. Mavman pretty much hit it on the head with everything though.
I would put my money on bad points. with a bad condenser you usually get some spuratic spark. The points need to be set with the rubbing block on the top of the distributor cam lobe. Set the gap at .017 to .021 and then with it running (not while it's running) adjust the dwell to 38 degrees.
Will try points and condenser next...looked at them yesterday, the condenser looks brand new but the points look like they may be no good
