    Nominal DC Current Draw?

    To be specific. It knocks the video signal out on my WinPro7 desktop. Sometimes I'll notice slowing in response esp. USB mouse. Anyway lemme log off before trouble occurs

    Nominal DC Current Draw?

    Ammeter reads 40 discharge to 40 amps charge With engine oiff, key off, headlights should show about 10+ amps discharge depending on lamp type and whether parking lights go off with headlights on. Vehicle with H4 lamps and sidemarker lamps...

    Nominal DC Current Draw?

    Aw common guys. I've posted this more than once. Both for diagnosing resistance in a circuit and for planning on loads an alternator needs to be able to supply. Do a search. I can't stay on this website and risk having it crash my system - which

    PLEASE HELP IM IN DIRE STRAIGHTSNo spark MSD but test fine what am i missing!

    How could we know that green was blue? and that tan was connected to J2-16DBL* ? We could only tell you based on the info you provided. You should have enough info now to figure it out. I certainly can't see what you have there.

    PLEASE HELP IM IN DIRE STRAIGHTSNo spark MSD but test fine what am i missing!

    Basically Yes. Power in ignition 1 (wire J2) and ignition 2 (wire J3) is used to signal the MSD to turn on. Ignition 1 is power to run the engine and that includes the alternator. One branch goes to the regulator so the regulator knows the system voltage. Another branch goes to a field...

    PLEASE HELP IM IN DIRE STRAIGHTSNo spark MSD but test fine what am i missing!

    I don't k now where what wires have been snipped. Joining the J2 & J3 is fine with an MSD, although not neccessary. My diagram is just a rework of the circuits of interest based on the factory diagram. According to the diagram The ignition feed went to a welded splice. I don't know if that's...

    All wires connected to the battery positive are hot even with key off. Alternator output is R6 and that you tell us is connected. Field wires J2 branch and R3 connect to the spade terminals on the alternator. The J2 (blue) comes from a splice in the J2 circuit. R3 must go to the...

    Your '72 was a wired with isolated field circuit. Explained here: Identifying Chrysler Alternators (1960-1976)

    It needs to be wired in. Charge the battery on a charger before restarting with the alternator circuit wired up. https://www.forabodiesonly.com/mopar/threads/charging-battery-with-alternator-warning.424783/#post-1972341430

    PLEASE HELP IM IN DIRE STRAIGHTSNo spark MSD but test fine what am i missing!

    The running voltage should be between 13.9 and 14.8 depending on temperature. It should not increase in with rpm. It should be the same everywhere in the main feeds. Just as important is the battery draw or discharge. The ammeter should be at zero (centered) most of the time. It should show...

    Left Parking Light Stays on

    The fact that lamp turns on when the key is in run (and start???) makes me think its somehting other than a ground problem. More so if this still occurred with the headlight switch connector removed from the switch. Put the key in accessory position and see if it still occurs. With key in...

    Remove the green wire and cap it. You'll need to figure out what the previous owner did there. That's an F_Up. The heavy black wire connection is better on the engine but it should work as drawn. The MSD 6 unless they've got junky will start with far less than 12 Volts. Go place a voltmeter...

    How about the instrument panel indicators? Do they turn on with the correct sides?

    Left Parking Light Stays on

    It could be a poor ground at the socket or the bulb base to the socket (less likely but happens). However the fact it is on when the switch is off makes me suspicious. https://www.web.imperialclub.info/Repair/Lit/Master/236/page01.htm You can do some checks so you're not throwing darts...

    This one is mine. For me, a little lawn is needed. Got to have some room to hang out and for the dog. The hawthorn provides some privacy and shade. I think next flowers blooming will be evening primrose. Big show was earlier.

    I think the the only way to learn is observation. Keeping it real neat and orderly helps too. I didn't do that this year. There's lettuce, raddishes, peas, carrots from last fall, some greens going to seed, and hakuri turnips that are also going to seed for reasons I don't know. nasturtium is...

    Best Electronic Ignition Setup for a 273

    2 bbl or 4 bbl 273? For best economy and performance you want a distributor with the best timing curve for the specific engine. Changing from points at the cost of changing timing curve to one that is less efficient will hurt performance.

    First the horn started blowing on its own, Then the starter cranks when you push the clutch in! wtf help!!!!!!!!

    If I was going to throw darts, it would be steering column. The right way is at this point is to disconnect the battery and test for cross wire short if there is nothing visually obvious. Yours is not a short to ground, its a cross wire short. I don't know what instrument cluster or what mods...

    With the clip out, the slot plate slide up and off the shaft. Wait, the clip in your photo? That's a royal pain. I don't have great tip to make it easier. Needle nose pliers and sometimes a very small screwdriver to slip between the shaft and the clip. If you want to adjust the timing from...
