Alternator ain't a chargin' 84 glt

Jesus Christ dude

Buy new positive and negative battery cables on amazon - cheapest I could find but for some reason negative won’t ship to California… probably doesn’t have a cancer warning on it



You battery connections look like dog shit

Also at some point soon or already needs to be done … battery is from 2021… 4 years old so it’s probably done for too
 
All that vitriol against the electrical stuff, and you didn't comment on the suitcase strap with S-hooks holding it down? :lol:

I wouldn't condemn a battery based purely on age, if it still reliably does the job. And yes, the cables are the wrong color, but they don't look as if they're in poor shape (as much as one can tell in a photo.) Certainly not dog shit... not compared to some of the cars I've seen and/or purchased.

IF the cable and connections are still solid enough to start the car, that means they're good enough to allow an alternator/battery to do their little charging dance... in which case I don't see how any of this is contributing to the OP's original reported problem. IF I've captured that correctly, then I'd recommend fixing only one thing at a time, otherwise you start finding yourself in a situation with 76 brand new parts and no easy way to tell which one(s) are defective.

Then go fix your cables properly. :cool:

… I was focusing on the charging issue and didn’t want to mention the other stuff like flopping in the wind IAC or relays screwed in all over the place…

batteries used to last a long time and the 240s don’t need many CCA to start but I would put monies down that “tested” battery ain’t got much life


There’s always a worse example for just about everything…

$40-50 for brand new positive and negative battery cables ain’t nothing compared to the headache avoided


These days that’s a ~tank of gas in a 240!

An example would be measuring from the center of the battery terminal to a few inches down the cable. Pierce the cable with the sharp tip of the probe. Anything more than .2v while the car is running is too high.

I checked for voltage drop with the car off between the (1)battery and (a) down the cable (b)at the starter (c)at the alternator (d) at the junction box on the fender well (wires to fuse), and found no drop. Then, I started the car and found a significant drop from the positive B+ post to the (d) junction box...(other probes [a,b,c] had no drop). Going to add new wire.
 
Well...I purchased a new set of cables, and one of the cables was back ordered, been waiting for over a month. In the meantime I cleaned some contacts and replaced the cable connectors that looked like they might have had corrosion. I think that it may be the original style 55 amp alternator is too small for the car. The electric fan is 10 amp, and I know there are still connections that need help. Anyhow, I'm going to put up a wanted post for a denso style alternator and keep plugging away, just wanted to update.
 
So, the cables never got to me, but.....I'm still an idiot. I made a new B+ cable and cleaned all the connections, and put the alternator(Bosch style 55amp) back on, and voila, I had charging. I drove it down the road a couple of miles and it went away again. Just like the first time, but this time I noticed a smell like burning rubber....it was the belt the whole time. As I mentioned, I'm an idiot, and the new alternator had maxed out the range on the tensioner. I had a smaller belt and had used it ( but I only had one ) and it seemed to be doing be the trick (but apparently there is a reason the pulley has two belts). So two smaller belts, and it's charging! I can now use my headlights and even listen to the radio!
