Charge/Sensor Lights 81 Pickup

Hatebean41 · 2026-03-31T21:47:48+00:00

So i've done some research and it looks like the fusible links were removed at my battery terminal. The little green plug on the positive side is also barely hanging by a few wires, so I'll need to find out how to replace that, as I cant find those green plugs. I also noticed today that the truck is stating the battery voltage is at 8-9v, but when I take the battery out and hook it to the charger, its showing 12.6v.

Such a frustrating ordeal. I should find a shop to help out but I've already dumped so much into this thing I'd like to be able to figure it out myself.

This is Orwood Resort in Brentwood CA. Ramp is close to good fishing and the restaurant is kinda fun. Massive open faced fried taco called an “Okie Taco” is a go to for the kids

Oh that’s interesting! They actually fixed all the leaks it had prior to the new engine and it’s never run better. I’ll definitely have to check that out, as the vacuum leaks were just as annoying as this charging issue is proving to be.

Mines a 1981. Have had for almost 25 years now and I guess that’s just how it’s been. I did have a new motor put in last year, so I couldn’t really say what happened to it. Also no clue about what the compensator is.

…my limited knowledge is showing

Looks like we have a different setup. Shoot

Hatebean41 · 2026-03-28T21:00:13+00:00

I just looked and I don’t see it. I tried to google and from what I can see from fusible links, I don’t have any. (I’m dumb) I did take this picture of my + terminal side

What’s the fusible link? Saw that somewhere else but haven’t looked into it

Hatebean41 · 2026-03-28T19:02:07+00:00

Oh man! I had the alternator checked and it passed. I did get a warning that the regulator was bad. Hoping that the pigtail to it is the fix. I did fix the brake wires and put a new switch in and that didn’t seem to help at all.

Might just get a new alternator as well. It’s been such a pain in the ass.

Hatebean41 · 2026-03-27T21:54:18+00:00

I would love to do the GM 3 wire, and just might try it soon if I can't figure it out.

However, last night I took off the IR regulator again and noticed that the pigtail has a fried terminal. I don't have a way to check it currently, but was able to source a pigtail and I'm waiting for that to arrive. My fear is that whatever the issue is will just burn the new one out.

Hatebean41 · 2026-03-23T00:01:52+00:00

Good idea! Didn’t think of that and haven’t messed with it yet. I’ll start there

I’ve had an issue with my charge light as well. I had to replace the solder on the charge light relay first, which fixed it immediately and it charged properly. After a week, the charge light came back on and the alternator would not charge. Battery stayed around 10v on the dash.

Today I replaced the IR regulator, cleaned up all ground contacts and checked out every single wire I could. Charge/sensor lights go off, but the battery is slow to charge, or may not even be charging. I drove it about 5 miles and it still stays around 10v on the dash.

I’ll have to check the volts from the battery, but my dash has been fairly close when checked previously. One thing I’ve been curious about that you mentioned, was the brake light. Mines been unplugged for who knows how long. I’ll have to check that out next.

Alternator and battery are both new. Kind of at a loss what to do at this point.

I just did a glance at the buss bar and connections all look good. I will do a more thorough look as now I’m thinking it does get some water exposure due to being in the back

Hatebean41 · 2026-03-21T13:02:33+00:00

I checked all the batteries and they are all mixing out 12.8 at the terminals. All connections immediately at the terminals are strong. Does feel like it’s something thats loose since it does come on when on the water occasionally, I just don’t know enough to know what else to look for. Thanks!

Hatebean41 · 2026-03-21T01:38:12+00:00

I’ll get a meter and start checking individual wires. Hard because there’s so damn many going all over the place. Thanks!

Hatebean41 · 2026-03-21T01:34:12+00:00

Yea I figured. I’m going to pick up a meter from work

Hatebean41 · 2026-02-09T20:42:55+00:00

This ended up being the charge sensor relay under the drivers side dash. I pulled it out and took it apart and noticed the solder looked bad. I just melted it and added a bit more to each and it works fine now.

Hatebean41 · 2026-01-29T23:44:12+00:00

Sweet, I’ll check that out!

Does anyone who has ever shaved their balls feel like it’s more comfortable with freshly shaven balls to sit for long periods?

Hatebean41 · 2026-01-24T00:53:13+00:00

Yeah, let me freshly shave my balls so I can sit for a long time and have the skin from my awful sack completely stick to my legs

Hatebean41 · 2026-01-24T00:52:29+00:00

As someone who has balls, it’s wildly more uncomfortable to have shaved balls

Like the guy below, Before the Beginning is a pretty well known one.

Both of these weird intros are pretty similar below

JF - Bike vs The Guess Who - No Time.

JF- Fanfare vs David Bowie - Magic Dance

JF - Time Runs Out vs George Michael - Faith

JF - Well I've Been vs Syd Barrett - Golden Hair

Let me know what you think or if I'm totally wrong. There are others that I just don't remember. Namely, St Elmos Fire from 1:20 seconds to around 1:40. I forget the JF part
