Q:Custom Power Supply Help?
Well as you probably know you are trying to charge a 1.6amp battery with a 1 amp charger. At the very least the charger is going to get pretty hot because you are maxing it out and a lot more. It depends on what the components are actually rated. I would think that it depends on how well you have the charger protected with fusing and the size, you will either blow the fuse or the charger.
Q:What was the first electronic device in the history of mankind.?
The relay was the first electonic- in a sense, component part other than switches and fuses, etc. It made modern telegraphy possible and evolved into the repeater- thus the relay- a remote controlled switch, was in effect the first ( Electronic) device, though not anything involving crystals, diodes, vacuum tubes etc. Morse devised the Relay as part of his telegraph system circa l844.

Q:What is an internal thermal fuse and what does it do?
Some components have an internal, non-replaceable fuse that melts open at a set temperature. The reason that temperature is used is that when an electrical component starts to wear out, More energy is required to keep it going. More energymore heat through the wires, and the wires are protected by fuses that melt when the power draw of the component exceeds their thermal rating, usually expressed in amps. The most common part that blows an internal thermal fuse that comes to mind is a Ford Airbag control module, and just replacing the module usually results in another blown internal thermal fuse. There ARE components out there that have a resettable internal thermal fuse called a circuit breaker. When the component draws too much power, the circuit breaker trips open due to excessive heat , then, when it cools down, it will reset itself. The most common component that utilizes a non-replaceable circuit breaker is a GM power window motor. usually it will go up a little ways, then stop and not work for a minute or so, then will go up a little more, then stop.This is the circuit breaker cooling down and resetting. Hope this helps.
Q:can u hurt a e.c.m. on a car using a test light checking fusses or 4 probing wires?
Don't stick wires
Q:2000 chevy metro Fuse blowing to take it out of park, why?
Some where in the circuit for the D range in you car is a short to ground weather it be right after the shifter all the way down to one of the solenoids in the transmission shift assembly? If you can find the short it'll fix right away? Have it scanned for trouble codes this might help find it? But major don't increase the fuse size this is extremely bad it will cause the wire the harness or the component it's attached to to receive vary high current this will cause the for mentioned things to burn and fail this could cause a 50-60$ repair to be at worst a 2-3000$ dollar reapir
Q:Why does my inverter keep blowing fuses?
Either you wired the inverter incorrectly, or the inverter has an internal fault. In the second case, it isn't worth repairing. Replacing the inverter costs less than FINDING the fault.
Q:How to calculate the value of a FUSE which is to be employed in a circuit?
I suspect that by 8g and 14g, you are referring to guage (awg), the cross sectional measurement of the wire, rather than grams, the weight of the wire. The general rule is 15A for14 awg, 20A for 12 awg and so forth. Once the load of the circuit is determined (say, 8 amps continuous duty and a momentary 18 amp start up), we must also consider the total length of the wire run and the resistance of the wire over this length if the source is a considerable distance from the load. If the run is relatively short and the resistance is negligible in this example, we can calculate the fuse needed to provide the power necessary while protecting the wiring from a short circuit and possible fire hazard.
Q:Transformer In-rush current, does it easily blow fuse and does it matter ?
What is the rating of the transformer, Input voltage, output voltage and output current? By 0.5 amps do you mean the input current of the transformer, because this would be the loaded current of the transformer.The transformer should not be blowing a fuse unloaded, transformers have a magnetizing current not an inrush current The magnetizing current is due to the inductance of the primary winding. Transformers act as coupled inductors and since the secondary is open the only load on the input fuse should be the small magnetizing current. I am guessing you might have a shorted winding.
Q:Big problem with my trucks wiring?
My first thought would be that you don't have a high enough rated fuse plugged in. I know they're color-coded AND stamped with the amp ratingbut are you sure it's the right one? Have you gone up a size to see if that helps? If you have a short, going from a 10- to 15-amp fuse, for instance, won't really run the risk of damage—it'll still blow. If you're confident about the rating or going up a notch doesn't help, you might have to disconnect everything on that circuit and plug the components in one-at-a-time until you find what blows the fuse. Once you have a suspect, pop in a new fuse and plug in just that one thing. If it blows again with nothing else on, you know where your problem is. Good luck!
