Power Accessory BAT

The fuse box BAT port shouldn't that be hooked to the Power ACCESS relay?

The box below has both circled.



If not and it comes straight from battery why is mine dead?

I kept popping radio fuses and it was because the hookup for the BAT is dead and it was

taking all the power from the fused end. Any ideas would be appreciated thanks.

I think I forgot the fusible links by the starter no?

Anyhow I will check tomorrow out of light , this fuse box might be a model of compactness

but I'd like to know what simple minded fool picked it's location.

If you ever get a chance to check out the late model Impalas the fuse boxes are

much better located.(Sides of the Dash)

How about CTSY-CLK fuse anyone have blow issues from orphan wires or bad lighter mines blown 4 incl a 25amp

that i used to see if it was slight load issue.(It's not)

Ok so the one bat terminal under the power accy is controlled by that fuse or circuit breaker i believe it is but its directly from the bat so its hot all the time, same with the other bat terminals below the ctsy clk fuse, those are controlled by the ctsy clk fuse but are also hot all the time. If its a fusible link and there are two at the starter, most everything power wise wouldnt work. If the headlights work and the tail lights and ctsy clk work then the fusible link is good, if they dont work, but then work after the car is running means that one fusible link is bad.

CTSY-CLK keeps popping and that has a lot of odd items  like emissions and map lights etc no?

I am sure there is LARGE short somewhere I am going to try and find it again today. It's weird

because everything was fine one day and all dead the next.

*I think it's the original lighter(I seen a lot of people have same problem with GM lol 1st for me) I pulled it out and

the  fuse is ok now. That's as far as the CTSY-CLK fuse but as far as the BAT it's still dead yet everything else

in the car works. Well except the glovebox switch lol oh well these electronics are pretty old.

Definitely putting a new fuse box in a saner location come spring with all new wire . I have almost everything

I need now but it's too cold for all that.

ctsy clk supports all the lights in the car like dome, hood, trunk, instrument lamps, cig lighter, glove box light, and ofcourse the clock.
No emissions stuff, other than that it seems kind of odd. Im sure the cig lighter itself was causing all the fuse blows, but the other bat terminals should have power.

Most likely the cig lighter. I can't tell you how many GM vehicles I've had where the cig lighter internally fails or the harness plug itself fails causing you problems. That's the first thing I check/unhook to see if the fuse still blows. I'll either replace it or unhook it. If I need it for GPS or phone charger or something, I'll just buy an aftermarket 12v adapter and wire it in to an auxiliary circuit and hide it out of sight or source a new cig lighter and harness for maintaining factory needs.

Really? You guys have has issues with the cig lighter? Huh. I never had an issue, ever. I guess i've been lucky

Ive never had an issue either, ive seen on newer cars that have the cig lighter in the center console where coins have fallen in and shorted out, or a charger fell apart inside and done the same. But mines original in the 79, but i dont use it, and it doesnt look like the original owner did either.

Here's the thing I wasn't using the original lighter it was shorting sitting in the socket. I did put a second one

in with a new lighter\map light where the clock was as the clock was DOA. As far as the BAT it's still dead I

haven't checked but there has to be it's own Fusible link as I said no other issues now, strange.......

I guess I'm just hard on them. I don't even use them.lol I can think of at least 7 instances where I've had problems with them. Maybe because I never use it??

This is why I like forums so much. This is the 1st I've heard of people having problems with them.
Mine have always worked or not worked, but never caused me a problem. Now I know they can.
