Hi,
Good for you!
Apparently you got close enough to the gremlin to scare it away from a grounding point.
I don’t see corrosion alone blowing fuses but only keeping things from working correctly or not at all.
Is this car has an automatic transmission or not?
I’m curious as I started with eliminating the switch position three as it was never said “just when the fuse was blowing?”
The car just stopped going and the PO made a deal to lose it.
I meant to suggest putting in a test light rigged up on the wire from the fuse in the junction block terminals over to ground to indicate blowing fuse.
With this light on shining out to you, when you wiggled the short or turned the key through it’s positions, it tells you exactly when the fuse gets blown.
I had it written this up earlier, in a longer draft and then changed my mind about how involved it was!
If there was something going on inside the engine compartments harness you would be right out there with it.
Even a mild sounding piezoelectric buzzer would be better as it can get your attention when hunting under a dash!
Either signal would have helped you during both processes!
Art’s written procedure, is of course, a lot simpler than mine ever could be!
Rip it all out and put back as needed, I guess?
I think backwards it seems, in smaller steps and not so willing to leap!
If the ignition switch was or is crossing up internally you would have seen it in a blink or with silence.
Both of those items are subject to the abuse of human hands and can suffer wear from various mistreatments.
Down inside the shifter of the automatic the parts are made of plastic. On both transmission types the wires or terminals can dangle or be rubbed by edges or carpet.
I was wanting to start later in the fuse panel, in the switch position two, after clearing position three as the possible fuse blower.
Now if the neutral switch or the engines harness wiring got have moved around that may have cleared it for now?
But since Art’s side of the hunt was inconclusive to nail it, it must be OK, like you said, “for now.”
Gremlins love to be intermittently playful and while in hiding in sheaths and hard to see places, they leave things unreliable.
Corrosion is usually green in color, just like the illustrated cartoon characters are!
If and when you do find them, they get to wear white coats, due to the winter months of salt festivity’s! (:).
Good olé aluminum grounds are those that “hide in plain sight” and are the special smiling ones, we say too, “That doesn’t look so bad.”
A 5 volt or less signals from BUS communication computers won’t help either! On the newest “Accessorized” combustion engine cars, that alone will sign cars into a scrapyard, at any age, fast!
My prediction is, we are headed into electric propulsion faster than we think! Engine oil and antifreeze might be all gone too!
I’ll be loving to know cow urine is “not” coming out of “any” Diesel exhausts, period!
The 240’s have survived by design to do a job with reasonability!
