    Interesting & creative tools, even if they are flops

    Predrilling still makes the strongest connection. Slotted has the advantage of applying full torque across the head and is the easiesto chip paint out of the slot. Definately requires a lot more skill than powering in one of the anti-camming torx type drive heads.

    Stop in for a cup of coffee

    Good! They hit pretty hard down here. Obviously I didn't make it out. In fact the car is still in the garage, but it does have fresh tires on it!

    Days like that can only get better. When stuff like that happens its a wake up call to reset!

    Bypassing the Amp gauge - Question about the MAD Electrical method

    I think the confusion here is just the commonplace terminology. Chrysler calls the key switch the ignition switch. Just about all the other companies did too. The feed to the "ignition switch" was labelled J1. J was substituted for I because I looks similar to 1. There's a number of other...

    Bypassing the Amp gauge - Question about the MAD Electrical method

    The wire from the main splice to the ammeter is R6A. The wire from the main splice to the ignition switch is J1 MAD's diagrams are generic. The diagrams in the immediately preceeding posts were figuring out a modified car with battery in trunk. As far as the electrical system goes, the...

    Gauge lights wont turn on 74 Dart Sport

    Weird only if you're thinking black is ground. Black is not ground. Power feeds in the car have Black as well as Red insulation. (The few grounding wires usually, but not always, also are black. You'll see an example on the headlight connector) The car has two power supplies; the battery and...

    Gauge lights wont turn on 74 Dart Sport

    For example, using the resistance setting on the meter, check the switch circuit that feeds the instrument lights. With the bulbs out, measure high beam to ground and low beam to ground. Also with the bulbs out, check the high beam wire to ground and the low beam wire to ground. Might be a...

    Gauge lights wont turn on 74 Dart Sport

    These shouldn't be too hard to figure out. If you have a multi-meter it will help. With the headlights on, did the high beam indicator light up? If so did it light up when the dipswitch was depressed? Knowing this could help. I like the idea of simple things first. Check the bulbs! Some...

    actual need for ballast resistor with electronic ignition?

    Starting sequence illustrated here 11 Volts during starting is good. 9.5 Volts at the battery during start is generally considered the minimum. Once the coil has developed its max energy level, any additional current flowing though is just generating waste heat. This can damage the coil. HEI...

    actual need for ballast resistor with electronic ignition?

    Ignition 1 is Run, and is blue or blue with trace. J2 J is used because I can be confused for a 1 Ignition 2 is for Start, and was brown, J3. At some point in the early 1970s, the ignition connection to the coil was given brown insulation instead of blue. Regardless, it is the feed to the...

    Any value in a old wiring harness

    Yup! And also it can be very helpful when repairing the replacement harness, both as a reference and for sections of harness. Can't tell you how glad I was that I save the original engine harness from my '67. It rolled up neatly and went in a small box. Totally agree that someone will want it.

    Alternator voltage

    I agree. measure the crank and alt pulley diameters. Then compare to the factory ratios.
