thrival, Welcome to this community, If you switch the mains voltage in to the 12 turns no wonder you are blowing the fuses! This is close to short-circuiting. You need to puls the feed or have a much higher frequency at hand if you are gone get away with it. If you want to change the ratio don

Audioguru, High Voltage does not necessarily mean hundreds of kilovolts because that would be arson. You must think

Darrin, How about a triac regulator for the AC power. This can be controlled by a feedback from a NTC. Ante ::)

Mark, The diodes are 1N5821 or similar and the resistor depends on the mA rate of the NiCad pack and the voltage at the input. The input voltage can vary from 12.7V (12V battery in rest) to 14.4V (alternator full charge). Sometimes the cells are marked trickle charge 50mA or some rate that is about one tenth of the capacity (mAh) value. It

vainajala, Yes, I am fairly sure it

Hi All, This site : http://www.terrypin.dial.pipex.com/ECADList.html is a nice survey of 60 E-Cad programs. I didn

smiler, This is one simple way to go: Here is a datasheet: http://www.elfa.se/pdf/73/730/07309016.pdf Ante ::)

Nettron, Looks good to me! But only for AC. Ante ::)

Smiler, Welcome to this community. Yes it is possible, how much current (A) do you need? Ante ::)

Darrin, Well I

Darrin, The capacitor is supposed to accumulate energy to supply the timer during the

Keile, Audioguru, How about using high voltage, then a spark will jump the break. A spark is easier to detect and no need to jerk the cable. This will of curse be lethal to any circuits connected to the cable but if you disconnect both ends before the test, why not? Ante ::)

Rhonn, Yes, the REF LO and IN LO shall be connected to COM. Ante ::)

Vainajala, I think this is one of them: http://www.allegromicro.com/skncatlg/pwrxtr/2sb1382.pdf Ante ::)

Mphotis, I suppose it must be a controlled burst and at a specific temperature? There are some factors to consider, temperature, pressure, time and volume. Do you have any documentation on the tests? Ante ::)

Darrin, Yes, they will be separated since you are using a relay for the pump. Did you notice any improvement with the 47uF that you tried? Ante ::)

Mark, Here is a suggestion; the backup battery should be a 9-cell pack. I suppose the 12 V line in your truck rises to something like 13.8

Mphotis, Have this sort of cooling been tested before? It sounds like a fast way to kill an engine! Ante ::)

Darrin, Try an electrolytic capacitor say 2200

Darrin, Welcome to this community. This voltage drop, is it only a very short drop or is it as long as the motor runs? If it

Hi All, Handheld scanner Realistic PRO-37 circuit diagram and/or service manual needed! The scanner loses all channels when the battery pack is removed even for one second. I can

Hi Mark, Welcome to this community. Is it standard to have 12 Volts in a truck where you live? In Europe most trucks have 24 Volts at least if they are bigger than 3.5 tons. I have a couple of questions about your radio system: How much current is needed to supply the

mbedford, All I can say is a stepper is very quick, much quicker than the power window motor! So don

Hi Rhonn, Do you know if the schematic you have used is updated, there have been some issues and a couple of errors if I remember correctly? Ante ::)
