Electrical issue
Hello All,
I'm having some electrical issues. I drove my truck the other day 80 miles and back with no issues. Now it won't start and I don't know why. Brand new batteries. Only a few months old. The cables are loose and I can't get them any tighter (corroded), but hasn't really been an issue. Dash lights, and wait to start comes on, but no fuel pump clicking sounds and no turn over.
1989 F250 XLT Lariat,7.3L IDI, 107,000 miles, automatic, non turbo.
Thank you
Robert

If the cables are corroded, the batteries won't charge right, and then the truck won't start.
Replace your cables.

YOu should see dash voltmeter reading in the Run position.
Have you checked fuses?
Or tried tried bridging the starter solenoid from the big post that goes to + BATT to the small post? This should turn the starter.

Get a voltmeter, even a cheap harbor freight one would help. Check your battery voltage. Considering the dash one isn't working, either your batteries are dead, some wiring is crap, or fuse/fusible link broke. But we really can't help you anymore until you figure out if the batteries are charged, and replace the bad wiring you've already admitted is on the truck.
You may be able to get away with just replacing the terminals, but if they are corroded, chances are the cables are bad as well.

So I jumped it yesterday and drove it 40 miles and when I shut it down and went to restart it, it wouldn't start again. I tried it in neutral it still wouldn't start. The dash lights and everything come on but not enough to turn it over. It took a second jump to start it.
Driving the voltmeter was in the green almost in the middle. Strangely had more power than normal. Purred like a loud diesel kitten.

Have you used an actual voltmeter to check the charging voltage while the engine is running? Have you load tested the batteries, and/or charged them with a charger? Have you done anything about the loose cable connections?
