Hi All!
First off, forgive my long-winded ramble. Just trying to give as much info as I can.
I went out to do my pre-snowstorm check on the Ford 1700, and discovered the battery was dead. It started immediately with a jump, but is not charging.
I also noticed the headlights wouldn’t work, and the charge/oil lights, and water temp gauge were out as well.
After checking all the fuses, I discovered there was no power to the fuse box.
Checking out the back of the ignition switch I had:
Terminal 30 (power in) Good with 12v
Terminal 50 to starter works as it should, as it turns over and starts fine
Terminal 17 to glow plugs works, but there is also a mystery black wire added to it that I have to figure out (although it looks factory, it is not on the wiring diagram). I know it is tied in series with the glow plug indicator, but there is a third wire I don’t know about.
Terminal 18 is tied into the other side of the glow plug indicator. I am perplexed by this, as although the coiled wire looks intact, no matter how long I hold the key on, it doesn’t glow. But it is definitely warming up the cylinders, and aiding in starting.
Lastly, the AC terminal (which powers the fuse box) shows no voltage when the key is in the on position.
I triple checked everything to validate my findings.
With that background info, now to my charging question. Would a lack of power to the fuse box interfere with the voltage regulator?
I ask this because, believe it or not, I had a similar issue with my Case 580k just two weeks ago. It would not charge. Turned out that the bulb in dash for the charging indicator was burned out, and that shut off the alternator! New bulb and it works fine.
So my plan is to buy one of those $20 after market ignition switch’s, followed by a $20 voltage regulator if that doesn’t fix it. The alternator is original to the 1983 machine, but I would rather keep it, then replace it with a $90 Chinese knock off.
Anyone have any insight/suggestions on my situation?
Thanks!
