General Dentside Chit-Chat

With a machine a you need to fine tune or doesn't hold an adjustment very well, that looks like a very trick pony. I've seen the Autometer ones, but never figured my junk warranted dropping the coin.

Even a couple of wideband O2's, datalogger and AF gauge can gain you a lot.
I've spent nearly 4 years with one program that the bikes use and it is a fantastic way to be able to monitor/tune everything.
The guess work is gone....you get concrete numbers....no more guessing as to whether you are rich/lean.

Quick question...for a 79, the #12 fuse (bottom right hand side) is the radio fuse correct? Is that a 15 or 20 amp fuse?

 

[Truckin4life]

I can say on almost every vehicle i have seen its a 10amp.
Even in my 69 ben.

Dammit to hell. Alright. I was undoing what the PO did to the radio/speaker wire yesterday. I got everything done except for actually getting the power wire in cleanly. So yesterday, I just had the wire wrapped around a hot fuse when the key/acc were on to make sure everything was working. However, I'd program my presets in and if I turned the Bronco off I'd lose my presets and every memory setting. So I was stumped there. But I did wanna get the radio hooked up to the right place in the fuse box.

According to da book from 1979.....7.5 A fuse

Ben, there should be two wires from your radio for power. One for the ignition so the radio only will power on with the ignition is turned on and one that is hot all the time for the memory presets in the radio. Sorry I'm not at home to look it up in my manuals....

[LEB Ben]

Alright thanks Duncan...so 7.5A and in the spot I thought it was?

Hmmmmmm...only power wires I had were accessory and battery lines coming from the plug. They were labeled accessory and battery. I put them both on fuses that were only hot when the key or acc. were on. Sounds like the Battery should be hooked up to a hot all the time?

 

[Truckin4life]

Ben, there is a memory wire, and a hot wire, hot wire is key on hot, and the memory wire is always hot...
Red is usually hot, yellow is memory....
Cant say about your stereo though.
Having them to hooked up correctly will keep your memory presets programmed until your battery goes dead.

 

[DNFXDLI]

Yep...#12 spot....and, if you gimme a few minutes, I'll see if I can see what colors are what on the radio harness.

Well the Acc wire is yellow and then battery wire is red. But at this moment, I have them both in a key on hot fuse.

Thank ya sir.

Did the memory work before on the presets? Maybe it's the radio and not the wiring?

Just read this again. If they are BOTH on a "key on hot fuse" then you don't have hot all the time for the red. The memory has to be on a "hot fuse" ALL the time.

[Truckin4life]

Red is key on hot.
Yellow is always on hot.
I BELIEVE...
I could be backwards.
I know one is always hot the other is hot only on key on.

Dunno the radio has been in a rats nest for the last 2 years and hardly worked to begin with. Good equipment...bad wiring.

Just read this again. If they are BOTH on a "key on hot fuse" then you don't have hot all the time for the red. The memory has to be on a "hot fuse" ALL the time.
Dak

So then where in the fuse box does each wire go?

 

[DNFXDLI]

According to the shop manual wiring diagram, there is a Y-Blk from the #12 fuse spot to the radio....this would indicate it is switched with ACC or IGN...so you will still have to locate a steady 12V for the memory...which would probably be easist to run from the battery.

 

[Truckin4life]

i was backwards then.

Run the red to the battery. Thats what i did.

 

[LEB Ben]

Alright...thanks Duncan. Shouldn't be too hard to do. Just as I was losing light last night, I didn't wanna to a hot all the time and either kill the battery or burn the bronco down...haha.

 

[dakonthemountain]

If you have to just run it straight through a fused link to the battery directly or to one of the other larger fuses (interior dome light, etc.) The memory takes like no power to maintain so it won't overload other fuses that are hot all the time.
