So I had aspired to begin replacing parts and going upgrades on my 67 Galaxie 500 with a 390 this weekend and have hit a road block before I even began. I've been pouring over threads on here and keep taking steps from this and that (like this one https://www.fordmuscleforums.com/igni...on-system.html
) Story is, last week it drove to work and parked fine, then wouldn't start and couldn't be jumped (although there were interior lights on). Got a new battery and it started right up, gauges and lights acted normal.
Then yesterday I went to start it and nothing. Opened the door and had interior lights, clicked ignition to on and the lights were still on, clicked forward again to start and nothing... lights out, no clicks, no noises, no nothing.
We've replaced a lot in the ignition system since rescuing this one and I'm trying my best to troubleshoot but need to call you guys in for some help on this one. Battery is new and multimeter says it's got a good charge. All battery cables and starter cable are brand new with good connections. New volt regulator as well. I replaced the solenoid this morning figuring that was the typical issue fix for this but no, still no lights or starting up. I got the Duralast Gold 3 year warranty solenoid. Multimeter is showing a charge at/from the solenoid, NSS red/blue wire looks damn near new so I think the NSS has been replaced at some point in the car's life. But I have not traveled the wire to find where it is actually located in the system and to check that connection. I'm still confused a bit with some wiring diagrams, just part of the learning curve I suppose.
Multimeter is NOT showing any current at the ignition coil, but it's very possible I'm not testing right. I tried each stud on it separately along with a body ground, zero current reading. Then moved on to checking the fuse box, all is well there. Took the dash apart thinking maybe something was loose with the ignition switch, all looks well there though, wires look newer like maybe it's been replaced before. Is there any way to check the current here?
The wire harness that hooks into what comes out of the firewall and then into the ignition coil look bad to me. There are 2 wires that have been bent a few too many times and the plastic has cracked and is showing wire. The only parts store I know that has this harness is closed on Saturdays... so that won't help me now. But aside from that, why wouldn't the interior lights be on? Car was running perfectly fine before its sudden death. It has brand new plugs and plug wires, just did the timing, distributor cap looked ok, and we ran some seafoam through to clean out some carbon buildup it seemed to have (which fixed a dieseling issue that had started). Purring like a kitten after that. Gas is brand new, just filled up on premium since she seems to run better on that. Currently has a 2bbl with electric choke.
What stupid thing am I missing? Any other points you'd suggest I check with the multimeter? If there are some please let me know where I should touch for the checks and what the readings should be, my green-self just hasn't learned some of these things yet so please forgive me. I was really trying to exhaust all search avenues and even throwing on new parts before asking for help, and I appreciate any suggestions to help me get this fixed. Starter? Condenser? Ignition switch? NSS? Just time for new wires all over? I was pretty excited to change out by 2bbl for a 4bbl and new intake manifold today, but that does me no good if she doesn't start lol
