    Headlight switch issue

    If it is the circuit breaker tripping in and out, there is obviously an issue with the switch or the load created by the lights or wiring is the culprit. I definitely would check the dimmer switch but a more popular way to remedy the issue is with a pair of relays, activated by the foot switch...

    Spark plugs

    Having used all three types of plugs, I'd have to conclude that Platinum and Iridium plugs are far superior in many ways. These plugs last longer and generally speaking are pre-gapped right out of the box for their specific heat range, which is pretty much non existent in Iridium. I agree...

    alternator swap, any conversions out there 66 polara 383

    If you were to install a voltage gauge you would quickly see why low power alternators are crap. Turn on your signals and the needle drops and fluctuates as with the brakes. Your entire electrical system is seeing these spikes and there just isn't enough amperage to go around with low power...

    alternator swap, any conversions out there 66 polara 383

    You can purchase a "period correct" looking alternator with internal voltage regulation these days. I highly recommend them as they are more accurate and responsive to voltage fluctuations. I went to the auto recycler's and purchased a Ford 3G alternator for $60 and it mounted right in place of...

    Intermittent / Weak Spark

    If you are doubtful of your ignition 12 volt supply I highly recommend a dedicated ignition relay to offload the ignition switch contacts. This is a very inexpensive upgrade and very easy to do. If you end up rebuilding the carb, the best kitt comes from Rock Auto. Do not, under any...

    Best place to get switched 12V?

    You can find a live ignition source (both start and run together) at the bulkhead. I believe it's blue but I'd probe the wires to be sure. What ever color goes to the voltage regulator or alternator field is the one you want. You will surely need two relays, one 30A for the pump and one 15-20A...

    Intermittent / Weak Spark

    First off, I'd put a timing light on it and see if the timing marks are "dancing" or hold steady a various rpm's. If they're all over the place the timing chain is stretched unevenly or shot, you have the wrong combination of drive gear material on the distributor shaft or your timing gears are...

    Non-starter

    There's quite a few things you can do to diagnose the issue but there's also a lot of components to check like the MSD unit, coil, wires etc and pickup in the distributor. Most require a VOM meter, patience, knowledge and confidence. I'll go out on a limb on this one and say the culprit is...

    Battery Help...

    Optima's are too damn expensive and don't always mount in OE trays and look tidy. Any quality AGM battery will do as good as an Optima, look more at home and save about half the cost without sacrificing quality.. But if you're one of those "just got to have one cause everyone else does" buy one!

    Vintage J-13Ys or new AP85s ?

    Yes it does! I actually run iridium plugs in my engine for a couple of reasons. There is no gap change either when the engine is cold or hot and there's less surface for carbon to build up on as far as the electrode goes. You can literally throw the whole "heat range" thing out the window with...

    Anyone find installing MSD unit worthwhile?

    I think MSD's offerings are good quality ( save the fakes coming out of China ) but I also think they're a bit of overkill on some cars. Read "The Counterfeit Report" .They have that mystique like i-Phones in that you just have to have one or you're not cool or a serious car fanatic. They claim...

    Headlight switch going bad?

    This is next to a pile of crap written by someone who knows little to nothing about ohm's law or the workings of an automobile charging system.

    Headlight switch going bad?

    Obviously, your alternator is not stepping up the output under load and that could relate to a battery issue, poor condition of the alternator or the voltage regulator. The regulator senses the system voltage and compares it to the battery voltage and increases accordingly. Your charging system...

    15 Volts

    The only alternators that will put out a constant 14.3 - 14.7 are OE's with internal voltage regulation. You are lucky to hit that voltage with an externally regulated alternator just by virtue of the length and condition of the wires that bridge them not to mention the rest of the electrical...

    Intermitten wiper switch

    This unit and others like it go into the "low speed" feed wire so that when you activate the wipers, it runs off the 12 volts that feeds the wiper motor. There is a time delay relay built right into the circuit that is adjustable. The link you posted has an icon for downloading a PDF file which...

    Need some help with radio, '71 Newport

    Just what the hell do you listen to on an AM radio? Mozart, Pink Floyd, Tammy Wynett. It's been so long I didn't know AM still existed with it's crummy sound and no stereo. Guess you could always listen to a baseball game or Roush Lumbard.

    It goes like this: 1-Can I afford to destroy it? 2-Can I get a replacement if I do? 3-Do I know what I'm doing or do I just think I do? 4-Should I really research what I'm going to do and learn about it before hand? 5-Is there someone who knows how to do it better than me and will take ownership...
