    Two Easy Fusible Link Questions

    Thanks so much for the input...that's just the kind of input I'm looking for. Dave

    24V Charging System Voltage

    I hope it is appropriate to ask a related question. I am pricing a new battery charger...one that will last me the rest of my life (the roll around kind, say 200, 100, 60 10, 2 amps as an example). I see there are two similar models but one will charge 24 and 12 and 6 volts and one will...

    Two Easy Fusible Link Questions

    I searched for "fusible link" and got no results...so here are my questions. After luckily averting an alternator-short-circuit fire (my wife's Mercedes 1982 380SL)...I have been rewiring the charging and starting circuits. In my case I am using new 0 gauge cable. My question is, would it be...

    Continous Solenoid: Normally ON vs Normally OFF?

    As a follow-up to my research, I've found a nice latching relay ($39) advertised specifically as a "remote battery disconnect relay". Its specs include: 100 amps continuous, 500 amps for 30 seconds. I called the manufacturer's tech support and after repeating my question several times I'm...

    Automated door opener

    In response to the curiousity question, what am I using it for...? It's wasn't my intent to mislead anyone, but I thought the explanantion on my first post would be better understood if I used an access panel analogy. But actually...if you've ever seen some of the newer Porsches you've...

    Automated door opener

    Message to CritchAutomotive: You cautioned: " I would strongly advise against using an electric motor, instead..." But you didn't indicate what it is you're trying to help me avoid...why the concern? And yes, you're right, it would be easier to elbow the panel shut but I actually envisioned a...

    12V Electric Fan Speed Control

    To MacGyverS2000 and curious125, thanks for the responses. I've got follow-ups for both of you: MacGyver: re the wiring... Here the dimmer modulated the fan speed: +12v----><----dimmer switch----><----fan---->ground Next, substituting a relay, the dimmer had no effect: +12v via Relay Term...

    12V Electric Fan Speed Control

    I've got another car improvement project on my plate today. I am trying to add a device that will moderate the speed of my electric auxillary fan so it will run a bit more slowly and, more importantly, much more quietly.  I've found at just a tiny bit less rpm, the fan is still very functional...

    Automated door opener

    I'm looking for a clever 12v way to open and close an access panel. Let's say the panel is18"X18"', basically a flat piece of 20 ga steel, hinged on one side. My goal is to have the opening side (opposite the hinge) move about 4" away from its rest position and stay there until triggered...

    Steering Wheel Command Center

    Carnage1: I thought it was important that the R1, R2, etc would all be different resistances, and then using your R2R idea, the S1, S2, etc. would each be double the amount of each corresponding R. Is that what you meant? Thanks. Dave

    Steering Wheel Command Center

    This is VERY COOL. I want one. Since none of my hair-brained ideas I have are 'overnight projects', this will fit right in. A diagram is worth 1,000 words. Many Thanks. Dave

    Steering Wheel Command Center

    To MacGyverS2000 and MLoew...thanks for the ideas. MLoew, I'm sure you're right on when it comes to the Indy cars...they MAY have 1 full turn lock to lock, probably a lot less, so a coiled cable is an easy solution. For my '68 classic, if I used coiled wire I'd have a mess of spaghetti less...

    Steering Wheel Command Center

    To MacGyverS2000, thanks for your quick reply. So in my case, where I may have only one but I think there are two slip rings, one represents the ground connection for the horn button. Assuming I have another slip ring available, let's say I wanted to flash my headlights with a new button A on...

    Steering Wheel Command Center

    Watching the start of the Indy 500 this morning I saw that the cars had many bells,whistles, warning lights, etc. on the steering wheel itself. This trend is evident with some auto manufacturers, as more functions are moving within direct eyesight and fingertip reach of the driver. Now...on...

    Ignition coil; heat as evil or resistance as evil

    To IRstuff, thanks a lot for the links to those other websites, they are very helpful. Dave

    Ignition coil; heat as evil or resistance as evil

    IRstuff and sreid, thanks for the feedback. IRstuff, as to the question, does it really make a difference...that's basically my question. I take it that you don't think it makes a big difference. Right? sreid, as to the point about wiring vs. a measurement problem, I believe I've used the...

    Ignition coil; heat as evil or resistance as evil

    I'm tinkering again, I moved my ignition coil away from its stock position (and the heat of the engine), so now it's as cool as a cucumber. I measured the resistance in the new coil wire just to make sure I had good connections and was flabergasted at the reading. Where 1.000 is bad and .001...

    Continous Solenoid: Normally ON vs Normally OFF?

    Doug020668...thanks for the idea. I've just taken a quick look at isolator solenoids. If I get your idea, I'd connect the isolator solenoid to my new convenient switch, where the purpose of the new isolator solenoid is to interupt the 12V+ heavy 1 gauge wire as it leaves the battery. So...

    Remote starter design

    Chancy, what a brilliant idea! Put me down on your product wait list. Sorry I don't have the kind of expertise to help out, but I appreciate the out of the box thinking (sorry that's now such an overused phrase)...you're using not-from-the-shelf-thinking! While you're brainstorming, I've got...

    Continous Solenoid: Normally ON vs Normally OFF?

    Re posts from circuit1952 and ubrales: thanks for the ideas! I can see why my terminology was wrong...it does make more sense to use the normally open/normally closed terms. Thanks for the caution on unexpected failures...something important to consider. And I like the fuel shut-off idea...
