    You SHOULD get a reduced voltage at the ignition coil CONNECTOR (Disconnected from the coil) when the key switch is in the 'Run' position, And full battery voltage when 'Cranking' the engine. (Keep in mind that battery voltage will REDUCE as the starter engages and cranks the engine. If you...

    INCORRECT. The 'Red' wire hooks up to the 'Positive' terminal on the coil, The 'Green' wire hooks up to the 'Negative' on the coil. If you look down in the coil connector, next to the terminals, you will see the small '+' and '-' signs next to the terminals. A Howell TBI injector takes it's...

    There are a couple of VERY good things to recommend the 'Stealth HEI' conversion. (Not an 'Upgrade' since there are downsides, that makes it a conversion, not an UPGRADE, which there are NO down sides to.) One is you can find the GM HEI modules in ANY junkyard! You can find replacment modules...

    Not really true, but some people have had ignition module problems... There IS ALREADY an ignition resistor (resistor wire) in the power feed line to the ignition module from the factory. That's not the issue. When you open up the plug gap, that demands more voltage from the coil, and your 23+...

    I would have to say 'NO' right off hand, although the way AMC/Jeep went dumpster diving for parts through those years, who knows! '77 Wagoneer should have the 'BID' or 'Breakerless Ignition Distributor' which is a Prestolite unit. (means NO breaker points in the distributor) Have a look at...

    The very early 4.0 engines have a set of plug wires that will work with the upgraded cap like a dream! They are exactly the correct size with the correct ends! 1994 4.0L Plug wires are PERFECT for 258 & 232 I-6 Applications! ----------------------------------------- As for upgrading a 4.0L...

    TFI ignition upgrade

    I've seen several examples of the 'Juice Box' product, and I wouldn't use it. I prefer to use better quality parts than they do. As for 'Idiot Proof', if you can do a simple tune up, you can do this. It's nothing more than Cap, Rotor, Plug Wires, and if you are ambitious, the coil. I-6 engines...

    NO. '74 to '77 CJ's ('75 to '77 FSJ's) used the Prestolite distributor and ignition module. There are currently no upgrades for this system since it was discontinued and abandoned after AMC stopped using it. -------------------------------- *IF* You have an AMC I-6 engine, you can switch over...

    TFI ignition upgrade

    Re: Questions and Answers And I got it from racing AMC's for 30 or so years. '82 gets you the screw down cap adapter. If you try other years, you might wind up with a clip down adapter, and that won't work with the '78 to '86 Jeep/Motorcraft distributor. Will not require any different...
