Hi guys,

Im going to modernize my elecrical system and have a question about the ignition switch config. (Caprice 1966)
I have an Painless 50101 fusebox, prewired, and trying to make myself an schematic before i cut the old wires. But i have no access to the car right now, so i hope some one can help me out with this one...

I don't know how the original switch is wired, and how the exact function is, so a little illustration of some sort would be much appreciated.

The 50101 instructions say:
Connect the ignition switch ACCESSORY wire to the IGN SW B+ terminal (brn).
This wire powers up the accessory side of the fuse block independent of the ignition switch.

My first thought here was, shall i make a new cable that goes from the "ign.switch acc" to the "ign sw b+" terminal, or shall i move the cable from the switch to the fusebox...

Or i'm i just plain stupido...

Thanks for your time!
Regards
/Pete

PS.
Miss you Doc...

okay, I'm a little confused, you are installing a painless harness?! if so, they have all the ign.wiring in the kit, and they are allready grouped into specific areas i.e.-steering column,ign,headlight group,ect... I guess i don't understand your question.

The Painless 50101 is a 12 circuit fuse panel only, no wires.

I am a little confused about the question also.

Hi !

I'm not the best to explain things... nothing new...
Well, i just bought the fusebox, not the harness. I,m doing the harness myself, or the parts that have to be changed that will say. It will be a lot of "own solutions", so the painless harness wont do me any good.

Sorry for the confusion...
Since i dont have a complete installation kit, or a installation schematic, i'll have to figure out the funktions of every part to see that it will be correct connected to the new fusebox.

Like the 50101 instruktion sayd:
"It will power up things independent of the ignition switch".
Well, i don't like to "bypass" the ignitions witch, so "things" get hot all times that should not be hot all times.

What i'm looking for i just a "drawing" of the ignition switch, and what is happening when you turn the ign.key.

Hope this help some...

No problem Pete, have you downloaded one of the Painless wiring kits manual? They have some very helpful diagrams in them that may help you with the ign switch wiring.

Vince,
I did some edit in the previous message...
There is just the "install text" in the manual, and it says "connect the cable" on all steps.
mmm... i have not searched for ignition switch over at painless, i'll have a look. If it is configurated the same as the original that will say.

I used a Centech kit in my 59 Elky
Since the 59 ign switch had no "ACCY" position, I bought a switch for a 64.

Battery power coming into the car will probably go to the 'Batt' position on the ign switch first and then daisy chained to the 'BATT' position of the fuse box.

It may be one big wire (8ga) coming into the car and then it splits into 2 10ga wires---one to the 'BAtt' position on the switch, and the other to the 'BATT' buss in the fuse box.

The "ACCY' should just be a wire from the 'ACCY' position on the switch to the 'ACCY' buss in the fuse box

Another wire that should be on the switch is the 'Ign' (or RUN) position.
This wire may run from the switch to a ballast resistor for the coil, (or resitance wire from the switch to the coil)
Or it could run from the switch to the 'IGN' buss in the fusebox, and power to the ignition circuit will come from the fusebox.

With the key in 'ACCY' you will want to power everything in the car EXCEPT--
--Ignition system, Electric Fuel Pump, Elec FAns or waterpump. Pretty much anything having to do with the engine---oh, AC compressor.

On my 59
Big red wire split into 2----one to fusebox----one to Ign switch
Big pink Wire------to 'Accy' buss in the fusebox (maybe it was a White wire)
And another wire from the 'Ign' post on the switch to an 'Ign' buss in the fuse box. (cannot remember what color---I'm not at home to look).

If your 66 is the same as the Buick switch and wiring for that year, you would have a resistance wire from the ign terminal on the switch going directly to the coil.

Oh,

Battery power all the time:
Headlamps/taillamps/brakelamps/courtesy lamps/radio and computer memory, hazards.

ACCY----car running or car off w/key on ACCY
Radio/heater/turn switch/power windows/wiper/wash/heat & AC blowers

Key on
Coil/HEI, AC clutch, Elec cooling fan relays, fuel pump- etc.

Key off---BATT hot at all times
Key in ACCy-----BAttery power AND the items hooked to ACCY

Key in RUn-- IGN + ACCY + BATT

Key in Start --STARTER only on many applications-----
On mine---START energizes both the starter and the ign circuit.

Bryan... Thanks !

I think there will be an MSD AL6/MSD 8361/MSD coil in the car, so the resistor mayt not be needed if i got it right.

And, it looks like i have something to read now...
But, i can see that i got the "funktion" i was looking for here !
If you got any more to add, i'll just be pleased !

Vince,
I'll found out other things that i needed to know also, by study other "complete" harness schematics.

Thanks all you guys !

No Problem
