Thanks Matt!

Thanks Fourtrail! I'll research how to do that once I get a handle on the wiring.

pgillespie20 I returned the coil and I have the ignition relay. I really appreciate all the input guys. I now have a direction for the next couple days

Hey Fourtrial,
The headlights and taillights are always on when the key is on. The brake lights work, but the turn lights and hazards do not. The PO told me he didn't finish connecting those.

The PO did several installs that I would call complicated like that steering column, Chevy powered seats, rebuilt the engine (w/ 289 camshaft, haven't figured out what the 289 # is yet), gas tank, distributor, and LED lights. But there's a lot of small stuff that wasn't right like 2 spark plug cables being swapped, the new spark plugs weren't gapped correctly, the timing was way off (fire was shooting out of the carb so I advanced the timing until the fire stopped happening thanks to another thread here) and there's always white smoke coming out of the passenger side exhaust (From research so far, sounds like a head gasket issue which will probably be out of my range to figure out on my own).

So far I've installed a new 4 bbl Edelbrock intake manifold, 4 bbl 570cfm Holley carb, fuel pump, fuel filter, fuel lines, throttle cable, seat belts and mirrors.

I found this steering column on ebay that looks like the same one I have from a 2001-2002 Chevy Silverado: http://www.ebay.com/itm/01-02-CHEVY-...657211/?_ul=CR.

I'm going to troubleshoot the column wiring from this article: http://www.jalopyjournal.com/forum/t...ummies.343068/. If it's not matching up, I'll call a Chevy dealer.

It will clean up the wiring and be more reliable.
Would this Delco alternator w/ internal regulator work?

Is this the correct wire for that alternator? If both of these will work, do all 4 of these wires go to my solenoid?

I just completed an H.E.I conversion. pretty simple... just needed to get a Switched power signal to the coil in the distributor.

Stock wires to the coil had a resistor built in to reduce the voltage to the coil. Make sure thats not still in the mix. I believe you need a constant 12V to the coil with H.E.I.... but check it out... this is based on my system not all systems.
The diagram that Matt linked gets 12V+ directly from the battery, you don't have to worry about the resistor wire as it's 9 or so volts is plenty to trigger the relay to it's on position.

Fourtrail Yes, pin 85 goes to ground. No you do not need to keep the coil, the picture is just showing the later model style coil connector. The - post of the battery should go to the block, then there should be a large wire from the block to the frame and also a wire from the block to the body tub.

John Strenk No, Just return the coil.

Yes, that symbol is for ground, You might find that sometime in the future it would be nice to install a ground block to make all your ground connection.

Currently the - post on my battery goes to my frame. Should that go to the starter motor instead? The solenoid does go to the starter motor shown below.
The ground cable to the frame is how the factory did it, which is fine, as long as the frame is grounded to the engine (usually at the motor mount). Hammer advocates moving that cable to the starter mounting bolt for a cleaner ground to the starter.

You mis-understand. You don't need another coil. As I said, the pin 86 wire just needs to connect to switched power. The old coil positive wire is a convenient place to tap into switched power.

That symbol denotes a ground.

Sorry I don't know more about this. Thanks for helping point me in the right direction.

Matt1981CJ7 Most guys wire the HEI thru a ignition switched relay like the diagram below. (compliments to Jeephammer for diagram)

Note, the relay pin 86 needs switched power. It doesn't necessarily have to connect to the factory coil connector, that's just a convenient place to do it.

pgillespie20 Since I have a HEI distributor, where should the wire from the distributor go? Currently, it connects to the battery positive side. If that is correct, then I'm thinking my ignition issue must be on the steering column side.
02-01-2017 09:35 AM
pgillespie20 I couldn't find anything online about that P141215 number to tell me what it was. Here are some pictures of the top 1/2. I can unplug anything and take more detailed pics if needed.
02-01-2017 09:26 AM
Fourtrail Yes that is HEI. As for #5, I looked again and that appears to be the brake light switch. Can we get a picture of the top 1/2 of the steering column, i.e. the key switch and turn signal switch.
02-01-2017 09:25 AM
Matt1981CJ7 Yes, that's an HEI, or a HEI clone. The coil is the part with the white numbers on it.
