Re: 69 El Camino distributor upgrade

well i have the msd 8360 ready to run installed with street fire wires and the points gapped out to .04 like msd says to do for the distrubutor. The distrubutor came with a part addendum for a 30amp/12v relay that is supposed to solve an issue with sending a solid 12v to the positive end of the coil. as of now its not starting it seems to be firing on all cylinders when i turn the key but wont start and dies immediatly after letting the key go. basically i have to keep trying to turn it over to get it to fire. i did install the relay Im wondering if i just need to run a new wire going from the starter or the wire that coming from the ignition? originally there were two wires tied into the positive end of the coil one being yellow and one being white braided which im understanding to be the low resistance wire coming from the ignition and the yellow going to the starter.on the 5 prong relay i have the yellow going to post 30 braided whit to 85 87 goes to my coil positive and 88 is my ground

Re: 69 El Camino distributor upgrade

You don't need the relay or the yellow wire, just 12 volts to the + connection on the distributor. Run a non resistor wire from the ign spot(where the old white braided wire comes from) straight to the distributor + connection and you are good!

Re: 69 El Camino distributor upgrade

Alright lol, so I got it started. I unhooked the yellow wire, I believe it goes to the starter selonoid; I unhooked that wire and put a wire going straight from the battery to the positive end of the coil... and she fired right up. I believe I can go ahead and trace that wire, and replace it with a new one. Possibly it's running through a ballest of some sorts that I'm needing to bypass.

My friend I bought the car from suggested I keep the bypass wire hooked up, and if all else fails put a kill switch in between. That seems kinda jerry rigged to me so I'll probably go the route of replacing the wire.

Sad cause I was kinda upset about going from stock points to to electrical as I'd love to restore it fully to its prime and this wire is one more thing thats unoriginal. My buddy has the matching number engine still that i didn't buy with the car as he wanted 10,000 more on top... but eventually I'll buy and have it machined and put back in. For now she will be my daily friver for sure I'll have to get some pictures posted soon and show her off!

Re: 69 El Camino distributor upgrade

$10,000 for the #'s matching engine? what is it a fully rebuilt LS6 ? that the VIN numbers are present on the block? but glad you got the MSD working I just reread it's a 69 so no LS6, L78 ?

Re: 69 El Camino distributor upgrade

he said the matching number engine if sold with the car adds 10,000 to the price of it but im guessing thats after its rebuilt and running, or just bs

okay so its the braided wire coming from the ignition switch that i need to replace. and just eliminate the yellow wire i believe runs to the starter? I'm guessing the yellow wire is necessary only on older stock points?

Re: 69 El Camino distributor upgrade

okay i think i understand. its like on my rv where i have multiple spots in the fuse pannel that i cun plug straight into with a blade connector. some are constant and some are swithced. so i can do the same thing and run a wire from a switch power straight to the positive end of the coil eliminating both the original wired running to the coil

Yes in the fuse box the "BAT" should be full 12V always hot and the "IGN" should be 12V switched that's IIRC that only gets 12V when the ignition is switched on.So for electronic ignition you need full 12V with the key on and full battery voltage to your ignition system so the engine runs.
But you don't have to remove that resistor wire from the harness just tape it off so it's secure and it doesn't spark and leave it there it won't hurt anything.But it will always be there if you decide to go back to points distributor or sell the car.

Re: 69 El Camino distributor upgrade

"Braided" wire is a silver stranded wire, it IS a 1.80 ohm ballast resistor.

To run something with a full 12 volts, hot in both start and run, cold everywhere else, do as above, wire a copper stranded wire from whatever you re running, to the IGN on the fuse box, done.

If 69 ElCamino is like 69 Chevelle, resistor wire plugs in large thru firewall connector below power brake booster. I had to remove booster to access connector.

Removed resistor wire and with a little luck was able to re-use factory connector on my #12 (?) wire to solenoid.

Re: 69 El Camino distributor upgrade

Just tape the unused wires to the harness bundle, they aren't gonna hurt anything!

Re: 69 El Camino distributor upgrade

What I recommend to do is remove the two wires, one frm starter solenoid, the other from the bulkhead connector, from the positive terminal on the coil, tape them up, then tape both to the wiring loom above the distributor and coil. Tjhis way, the loom has not been altered, the ballast resistor and start bypass are still in place and active.

THEN, DO AS OUTLINED, TAKE A 12 GAUGE WIRE FROM THE COIL POSITIVE POST, ROUTE IT BACK THROUGH THE FIREWALL, TO THE FUSE BOX IGN TERMINAL, D O N E.

Leave the bulkhead connector alone, no need to hack it up, either.

No need to butcher up the thing, this isn't brainage stergery, folks.

Removing resistor wire from bulkhead connector and reusing its’ plug on a new wire does not

a-“hack up” the connector or,
b-“butcher up the thing”

Re: 69 El Camino distributor upgrade

OK, if you say so, and, you have done ignition work for the last 45 years, designed and developed the large cap HEI with others at GM, I don't think so, no, I KNOW SO, you didn't, and aren't.

Now that you have butchered the wiring loom, torn the resistor wire out, what are you going to do it you need that resistor circuit to limp home on? IT ISN'T THERE ANY MORE.

The way I described, KEEPS THE RESISTOR IN PLACE AND WORKABLE IF NEEDED, AND ADDS THE FULL 12 VOLTS. Oh, yeah, you know more about it than anyone actually having those 45 years of experience, I defer to you.
