    repairing CDA-7897?

    going to betray my noobness, but I might as well ask... IS there any product that can take a usb or aux input, and communicate with this deck? maybe going through the input that is currently the CD player (which my father had bought along with this deck).

    repairing CDA-7897?

    awesome!! I look forward to the pics Thursday, I myself will be free on Saturday to actually take the unit apart. 24 hours...! do you at least get to nap between calls?

    repairing CDA-7897?

    Hi! This was my father's old stereo, and I've had it for 4 years. Two nights ago it broke. I'd like to give a shot at repairing it myself, if I could get a little push in the right direction (or: also an answer like, it's not worth it/ parts can't be found so you should throw it out is also a...

    capacitor help-- supposed to discharge itself?!?

    Hmm. The fact that it seems like it is that simple... means I'm probably not getting something. I hadn't meant of course to open a can of worms with a capacitor thread: just wanted to know why it was discharging itself when unhooked. And I'm glad it worked for me, of course; it was a...

    capacitor help-- supposed to discharge itself?!?

    Figured I'd follow up on this! I installed the capacitor yesterday, and, to my great relief, it works perfectly. Where before every time the fan kicked on, the engine would suddenly buck and rock the car as it stumbled to 200rpm and maybe recovered, maybe didn't; now... nothing, sweet...

    capacitor help-- supposed to discharge itself?!?

    Chemmins, reread what I'd written before you're so quick to call me an idiot. 2k ON THE ALTERNATOR. 6" crankshaft pulley. 2" alternator pulley. 700rpm @crank =2100rpm @alt =>80amps. Thanks audioholic; I might be returning this one then. Not much could be wrong: charge it with a battery...

    capacitor help-- supposed to discharge itself?!?

    yeah... I know that. In fact your estimates of 70-80amps are exactly what I came up with myself (80amps @2000rpm on the alternator, according to the manufacturer... and given 700rpm at hte crank and roughly a 3:1 pulley ratio...) Which is enough to run the fan continuously but not enough to...

    I could also consider an inductor to delay the current draw/ cut back the current spike to the fan.

    capacitor help-- supposed to discharge itself?!?

    I thought that the resistance of a capacitor went up as it approached equilibrium with the line voltage. It seemed really to stall at 10.2 volts. I thought the resistor was only to slow the charging of the capacitor on the low end, when the capacitor was still at just 0V, and after that the...

    capacitor help-- supposed to discharge itself?!?

    I've got a brand new 130amp alternator with 0 gauge wire going to the battery, and a 1040cca battery. Not sure how much further I can upgrade those! To the fan, admittedly, I have a sum 24" of smaller 10 gauge wire between the battery and the point that the wire enters the fan motor. There's...

    capacitor help-- supposed to discharge itself?!?

    could you explain how exactly I charged it incorrectly, and whether it's still any good?

    capacitor help-- supposed to discharge itself?!?

    Should it discharge even without any draw on it? I thought it would act like a battery, hold charge if there's no load-- even if it's not quite the deep ocean of amp-hours that a battery is. It was a line item at the end of my previous post, but I should maybe explain how I'm using it more and...

    capacitor help-- supposed to discharge itself?!?

    Mind you I've never used a capacitor before, but I've read the literature, remember my high school electricity&magnetism, and believe I get it. I just got a brandy new capacitor in the mail yesterday, was going to install it tomorrow, decided to charge it today. Err, apparently any sort of...
