    Need help w/full wave bridge rectifier

    Hi Ante, I failed to recall that I had posted a similar post seeking help with understanding rectifiers on this particular forum. My apologies to those who shared their time and knowlegde in response to my original post. I assure you your efforts in helping me are very much appreciated and have...

    Need help w/full wave bridge rectifier

    I am seeking advice on how to determine what voltage and current ratings a bridge rectifier is required for a charging circuit. The circuit consists of a stator, 12 volt lead acid battery, 12 volt DC accessories, and the rectifier. The charging circuit produces a maximum of 7 amps DC current. ...

    lightbulb's role in car amp

    Uhh.....umm... Well...eh...alrighty then. Sounds like you had yourself a blast! Keep up the good work!

    Bridge rectifiers

    Looks like Greek to me. lol Perhaps adding a regulator is not what I should be focusing on. I'd like to be sure I am grasping the concept behind my outboards charging circuit. The stator is rated at 200 volts AC , 7 amps. Between the stator and battery is a rectifier to switch AC into...

    lightbulb's role in car amp

    Thank you MP and audioguru. From the detailed information you've each kindly given me, I don't feel quite as much in the dark as I was before. Why use a light bulb instead of building a circuit that would do the same thing? Usually there's concern when using filament bulbs in areas subject to...

    lightbulb's role in car amp

    That makes perfect sense. Thanks Ante! ( This forum shreds) 8)

    Bridge rectifiers

    Considering that we have taken our little 17 foot Bayliner Capri some 60 plus miles offshore numerous times would make most have to question our intelligence out on the water. Such is the draw of the ocean. We do have a kicker motor on board just in case the main should fail us. One bit of...

    lightbulb's role in car amp

    Inside my car audio amplifier I noticed a very tiny tungsten filament light bulb. I cannot for the life of me figure out what it's purpose is. The layout of the components on the PCB is extremely clean. Here's a link to the schematic I was able to download free after I visited one of the...

    Bridge rectifiers

    Using a regulator is something that I will no longer go without. Ruining batteries due to overcharging them is getting very costly and more then I can currently afford. Plus...replacement CDI packs go anywhere from $160 to $399 each. Loose or bad battery connections or a battery that is...

    Bridge rectifiers

    Hi Hi Kevin, Since larger diodes provide better regulation then smaller ones and how most similar-in-amperage diodes (to the OEM rectifier used on my outboard) all seem tend to have a centered hole for fastening it down to a bracket or mounting location, are probably two factors they may have...

    Bridge rectifiers

    Hi Dazza, I'm not certain if you are still interested in the developement of this thread but this is what I have been able to ascertain thus far. After consulting an outboard motor specialist on a forum specializing in outboard motors, I was informed that since my motor does not incorporate a...

    rounding off sq. roots

    Well Suraj, I'm just happy that my friend will now no longer be able to back me into corner in this one area of discussion. Although, it only does so in a round about way, the link to the psuedoscience page you posted most defineately confirms my theory. With the information I have now...

    Car stereo amplifier output ratings

    What's even funnier is that it doesn't matter what claims are made as far as amplifiers and electrical watt ratings. When it is musical watts that we hear. And musical watts at normal listening volumes are way low. P.S. I have one thing to say about discrete transistors vs. mosfets. And that...

    rounding off sq. roots

    My friend insists that it is impossible to determine the square root of pie because, as everyone knows, you cannot fit a square into a circle. I told him it can be done as long as one remembers to round off first. :o
