    OK, so I am still trying to get this darn '83 K5 w/350 running. It has an HEI distributor on it. I basically figured it was the actually distributor since I have 12V goind into the cap, new cap, rotor, coil, ignition module, but no spark. I bought an HEI off of JK5 here on the forum. I was about to put it in when I saw that there was a wire spliced into the 12v connector and it uns to a connector, but isn't plugged into anything. What is it?

    Are you referring to the connector that runs out of the distributor itself? If so that plugs directly into the cap. You also need a seperate 12v bat source that runs to the BAT terminal on the cap. Don't get it mixed with the one right next to it that is for the TACH (tachometer).

    No, I mean that there is a wire spliced into the connector that connects to the BAT on the cap. The wire goes for about 8" and then has a connector at the end.

    That is not stock and it sounds like someone needed battery power and thought it was a good idea to rob the power from the distributor (not a smart idea). I'd take it off and forget about it.

    Here are some bad pics of the connector at the end of the 12v wire.

    Ok well fill out your profile so we all know what year vehicle you're working with. For all I know it could be a stock option or it plugged into a sensor that sensed how much voltage the dist was getting.

    For a 74 K5 I can tell you that it isn't stock.

    Yah, actually forgot you included the year there. Still the profile thing stands tho, it just helps everyone out in case you forget to include pertinent info.

    No problem on the help. Thats what we all are here for.

    Jerry, don't worry, the dist. you sent me was perfect. This wire I am talking about is on the Blazer itself.


    For all of you Profile Nazis I filled out my profile. /forums/images/graemlins/laugh.gif
