engine electrical

Just wanted to throw this on here real quick. I'm not going to adress this tonight but want to see what comes up before I get to wrenching again.

I just rewired my engine compartment wire for wire except the fact that I bypassed the EECU and went with an MC2100 and ACCEL ignition and Nutter Bypass. I could have a bad selenoid as it is the only part that is not new. I just started it for the first time since I started this adventure. It starts and runs beautifully. When I turn the ignition switch to stop, it doesn't turn off. Had to choke it off. I have done a little bit of under dash stuff, but othing that should have to do with ignition.

I dunno. Deal with it tomorrow. Whaddya think?

What 'Accel' ignition...?

My guess is you need a diode in your alternator wiring.
Cheap, simple, easy to do.

Try this, unplug your alternator two wire connector, and see if the problem goes away, if so, I'll dig up the part numbers and diagrams to get you fixed...

If it's something I can pick up at the auto parts store on the way home from work, I'll just get one anyway. So which diode and which wire needs it? Thanks.

Yes once the two wire plug is disconnected, the ignition switch will turn the Jeep off. Now? Thanks.

Got it. Thanks. Now it's prolly gonna say in the packaging or something, but does it matter which way it goes on? Thanks for all the help. It's gonna be ready for Thanksgiving!!! Just have to get my new steering box on and I'm set. Thanks again.

Yes it does. There should be a little white band on one side of the diode

The schematic is shown like this --->|--- The vertical strip desgnates the end with the stripe.

Hey John! Missed you for a few days!
Some gauge questions out here I don't have the answers to!
(Looking forward to your answer since I'm having the same problems)
I told them to get a hold of you!
Just what you need! More job with no pay!
------------

This is what your diode installed should look like...


Radio Shack has the diodes and those little non-insulated crimp connectors, but their heat shrink tubing is the shiny vinyl type that isn't good for anything...
NAPA is probably your best bet for the rubberized heat shrink tubing with the glue to seal things up inside.

Diode, Radio Shack p/n 276-1143 and if the local store doesn't have it,
you can order it on line, but if you order it at the store they pay shipping to the store.

The new plug (If you need one, is under $5 at the local discount auto parts stores.

Thanks Hammer. I already replaced the guts of my old plug and have planty of different sizes of good shrink tube. I greatly appreciate the help guys. The Jeep has been under the knife for 5 months now and I finally get to go wheel it on Thanksgiving with about $2,000 in new parts. Thanks and thanks again.

The Diode works perfectly. Here are some pics of a bypassed EECU. Sorry some of the wires aren't OEM color, but feel free to ask a question. I did this myself, with no previous experience in wiring up an engine. I just studied the diagrams and took my time. It's not that hard. The nutter is fuzzy and the new black is supposed to be purple. A few of you have asked questions about this same thing. So here it is. Anyone can do it.






And here's my new steering just for giggles:



Thanks for all the help.
