electrical newb question

[Smokinthehippies]

ok this may seem pretty simple i'm hoping someone can point me in the right direction.

so on my rig theres a few accessories that are plugged into the fuse block where a fuse would go.

i had one pop the other day and now it gives no life.
where would it have popped? is there like a fusible link or something i'm not seeing?
as it stands i think almost all of my un used key'd on places are burnt right now. not gangster.

how can i fix it. how should i install/remedy the PO setup so that this situation doesnt continue.

In my experience fuseable links are generally for the alt and equipment under the hood as a secondary means of protection.

I would start with removing what PO did and recheck as he may have overloaded the circuit. There may be a larger fuse protecting the ignition block under the hood also. And always double check your grounds. 80% of car electrical is due to lose grounds.

Car electrical is not my strong suit, as I generally do home and commercial but this should get you started.

Hope it helps.

Thats a good question. The fuse block its self is pretty much protected by the main fusible links.
Some of the unused fuse holders may be powered by other fuses in the block.
How are you plugging into the holders? Do you have a little piece like a fuse end that fits the socket?
Or are you talking about the spade terminals that some fuse blocks have?

Let me dig through my schematics for an 81, and I'll see.

i know the grounds are solid. cuz i redid a lot of those. these are things where accessories quit working. while tracking it down i'll here a "pop" when playing with the connection and then that slot on the fuse block will be dead. i think overloading the circuit is exactly the problem. i just need to figure out how to un overload so i can use them again.

all the connectors look like this. just stuffed in betweeen the ends of the positive side of the fuse slot. i can go and check all of the fuses in general. i wanted to switch to new ones anyway as i have some that light up once theyve popped. should be a nice thing to have in there.

Just goes to show how hard turkey hunting is hammering me. I was thinking you had the older glass fuses......
The only schematic I have for an '81 fuse block, is not really clear. It looks like there are fuses between the different busbars
If so, they may be some of the fuses you see, or there may be some internal fuseible links inside or behind the block.

Don't remember ever taking one apart. I'll be someone here has.

 

[Smokinthehippies]

Bump for any other ideas until I can check the remaining fuses.

 

[Smokinthehippies]

Replaced all the fuses. Found one that was cooked but replacing it did nothing for my problem.


Also. Wtf is this? Would it be my problem?

That looks like a flasher, so doubtful that it's your problem.

Plugging things directly into where a fuse should be defeats the purpose and leaves you with no fused connection. It could be that the wiring inside the fuse block is now toasted since there was no fuse to protect from an overload. I hope that's not your problem but I don't see much else that could be the case if you have no power at those spots on the fuse block.

Ah see that's half what I expected to hear was toasted wires.

In theory. How should one attach to the fuse block to get switched power while still getting a fuse? I have no problem doing it right.
I don't think that's a flasher tho. I thought the two round silver things were for the flashers? Oh he'll who knows. Need to just replace the harness.

You're right, the round ones should be flashers. That must be a relay, but I couldn't tell you for what i'm no electrical wiz, so do totally quote me on the possibility of burnt wires, but that's what I would think would be the culprit. I assume you'd need to tap into fused power from inside the fuse block, or do it the way it was but run an inline fuse to the accessory.

This is what I use as a temporary fix

I use these as a temporary fix. If I need anything else for regular duty I install relays.

They work wonders until you blow the main fuse, but in a perfect world an inline fuse would be the next thing attached to the brass clip.
