    Gap for brazing thin casting? Non-automotive

    The register has a patent cast in for 1872 which helped me figure out the manufacturer was Tuttle and Bailey, which was mostly unreadable in the casting.

    Gap for brazing thin casting? Non-automotive

    Took a while to get all the patches in the wall and pieces test fitted. When the paint is dry I'll put the working register in. and then the grill. But this is a test fit with a spare grill. Still working on a copying the control rod threads for the register that allows heat to go up the...

    IGN. SWITCH

    But it also should not care if there is a ballast resistor. All that has to happen is the small red wire get some power and the MSD will turn on. Maybe the now common 1.5 Ohm + resistors are an issue. Not an issue with .5-.7 ohm resistors. This is the basic setup Since in this case its a...

    Chasing a parasitic drain on the ammeter circuit

    ^^Sounds lgood^^^ Maybe along the same line of thinking. Disconnect everything. Then start reconnecting, first at the starter relay juntion, then the firewall, etc.

    What is 'Hot Car' in a 1966 broadcast sheet?

    A photo clearly showing the code is 696 here https://www.forcbodiesonly.com/mopar-forum/threads/1966-fury-iii-wagon-fender-tag-broadcast-sheet-decode.77195/ Here's a description of "New Car Service for All Customer Driveaways"...

    Chasing a parasitic drain on the ammeter circuit

    So do the door switches. The dome light is powered through a fuse. Removing the fuse didn't stop the mystery current. Suppose its possible there is a weak short in the headlight switch...

    Help please...Dart swinger elictrical problems.

    Here's the basic scheme. The battery wire A1 only has current flowing through it during start up and recharge. The ammeter shows 40 amps discharge to 40 amps charge. Generally the battery should charge at less than 10 amps. And should be fully recharged (0 amps) after a few minutes. Starting...

    Chasing a parasitic drain on the ammeter circuit

    IDK. Maybe you got this covered but skimming this again now, maybe not. These cars are not fused like a house. A lot of circuits are unfused. There are various reasons why which we don't need to spend time on now. Point is that pulling fuses only gets so far. No clock or convertible top...

    Help please...Dart swinger elictrical problems.

    Doesn't seem stock. Your car did not come with a voltmeter. it came with an ammeter. The reason the factory used a fusible link was to allow more than 30 amps briefly. A 30 amps spike is OK. 25 amps for an hour is not so great. Probably the best thing to do is look at other simialr...

    Chasing a parasitic drain on the ammeter circuit

    '68 Dart? And you pulled every fuse? Radio should be on the switched (accessory) buss. And I would think with presets its still 'off' with the presets stored internally with its own battery. But just in case, disconnect it. A/C should have no power with key off, but again, disconnect it - it...

    Charging system

    Probably best to redesign the system. It new strategy to deal with the new goals. That stuff will be running on battery with the engine off. Additionally the battery will get drawn down further. As a result there will be high charge rates unless you have a way to control that because the...

    Charging system

    I would say the factory team had a reason for just about everything they did. Some of us are now old enough and experienced enough to now be a bit humbler about "improving" the "stupid" things the factory did. Also maybe a bit wiser in asking the factory system to do things it was never...

    Charging system

    Yes, no, yes, no. The diagrams in the FSM are about as good as you can find. Redrawing the circuits of interest is SOP, and was recommended in both Master Tech Service Conference sessions about how to use the diagram. The alternator and the battery are both power supplies. Each has a...

    starting issue with mostly stock 318

    This one. https://www.forabodiesonly.com/mopar/threads/6-5-years-on-a-battery-new-personal-record.574940/ So worth seeing how well the battery is handling the load by checking voltage during the start. That said, I'm seeing similar on my Jeep - a very brief swing to high charge immediately...
