Q:Is it better to disconnect the positive or negative cable to a car battery?
Just answering the first question. Always- disconnect- the(negative) cable first no if ans or butts. For no reason should the positive cable EVER be disconnected first. Nor should it be connected last EVER.
Q:Can a voltage multiplier (such as a cascade multiplier) be built with easily obtained electronics components?
yes, you can use ordinary diodes and caps for this. The difficulty is in adequate separation and insulation between stages. For example, if you start with 120 volts ac, from a simple isolation transformer, you can get 160 volts per stage. You need 400 volt diodes, although I'd get 800 volt ones for extra margin, such as 1N4008, as the price difference is small. For the caps, it depends on the current. I'd get perhaps 20µF caps. You need only 200 volts, but I'd try for 400 volts for extra margin, in case one stage dies. reference has more details. edit: I'd be sure to use lots of fuses, like 1 amp ones. And I'd get some high voltage resistors, so you could build a voltage divider to measure voltages. For example, a 100:1 divider could be a 99 M ohm and 1 M ohm. The 99 M could be 4 - 22 M and 1 - 11M. You may have to adjust the 1 M upwards to compensate for your voltmeter resistance. A thousand to 1 would be a 1 Gohm resistor and a 1 M resistor. You can get the Gohm from places like Victoreen, or build it up from smaller resistors. Note that 1/4 watt resistors usually have a max voltage rating of 450 volts. I have seen web pages that go into detail on how to do this, re epoxy and other techniques to maintain the high voltage. .
Q:Why is my fuse blowing all the sudden?
most likley when the bass hits its hardest or deepest its to much for your amp so it blows your fuse try turning your bass booster down or the bass alltogether.
Q:1996 Cadillac Eldorado ETC, No power to Fuel Pump - Filter, Fuse, Connections & Relay all good, what can it be?
1996 Cadillac Eldorado Etc
Q:Car speakers won't work, any help greatly appreciated?
I suppose it's possible that when the amp was disconnected from the fuse it blew it out or something like that. If you can reconnect the back speakers to the stock amp and they sound OK you know that the problem is with the amp, not the speakers. Also try just putting a new fuse in the amp (they usually come with an extra fuse.)
Q:i have a fuse slot that is not working which killed my mass air flow sensor. Does this mean the wires going to?
Put a fuse that is correctly rated for that slot. Turn the ignition on (engine off) and see if the fuse pops. Right now you may have a short in that system. You need to recreate the situation that popped the fuse in the first place. The only way for wiring to go bad is to draw to many amps through the wires that will in turn, melt the wires. The fuse box is there to protect the vital components of the car. If the mass air flow sensor is not working, the car will not stay running. It will start, but not stay running.
Q:2000 mercedes ml320 power seats dont work?
Since you say it applies to both seats, the fault is most probably in a component common for both seat circuits. That would be the relay k1 (looking in the direction of travel it will be on the left side, top, close to row of fuses above it) in the right front footwell relay/fuse box. I presume you also have checked already the fuses f30 and f31 - they supply the power to both seat modules, there are orange (quite thick) wires coming from the fuse box to each seat. Please check if the seat modules are getting power. The other possibility is lack of seat activation signal (it comes from the AAM (All Activity Module) in the front left fuse box, via grey wire and it simply enables the seat by activating the relay k1. might want to try if applying battery power there (gray wire, connector 1, pin L) of the front footwell fusebox will make the seats work. Funny thing i was working on similar problem on W164 ML couple of days ago.The thing cooked down to faulty front module that did not supply the seat activation signal anymore.
Q:what is wrong with my power windows?
Here are the components to check: The fuse, the window switch, the window motor and the regulator. The regulator is a cable mechanism that actually moves the window up or down (not the same as the motor). If it does not move at all, the fuse, switch and motor are the things to check first.
Q:2003 dodge grand caravan the park lights wont come on?
when you open the door look on the end of the dash on that van, there's a panel that you remove,there you,ll find the main fuse box for the the inside components and the one for the park lights,good luck.
Q:mercedes 83 300sd fuse for the clock?
Simply look at the fuse box and it will tell you what fuse and the power of the fuse to use.
