Marine electric power supply

My power for the sparkplug is supplied bya magneto setup similar to a mower. What baffles me is that it has a start and stop switch one end of which is connected to the condenser then other end follows the sparkplug lead for a short distance and was then cut off? where should that have gone?Earth? so engine would stop if switched to that side?.My engine is an early Valmet single cylinder 2 stroke engine if that helps any?

This was posted in car audio amplifiers for some reason. You should try posting it in a more suitable forum to get more reliable answers.

If I had to guess, the wire was used to ground the spark plug to stop the engine.

I have a Power Acoustik Dem0n II 6000w amp. Every few seconds or so, it cuts off. In addition to the constant power outages, the amp is almost always hot. Can someone tell me what the problem might be?

be sure the amp is located in a well ventilated area as heat build up can cause a safety override to cut power once temp. reaches a certain point. amps do generate heat though so if you dont think its cutting out due to excessive heat building up, i'd definitely get a power capacitor to help keep a steady supply of electrical energy available for instances where the bass hits really hard or for prolonged periods of time. if you have a power cap already make sure it doesnt need to be upgraded to function properly. hope this helps!

I want to connect a kenwood how to connect a kenwood KAC-81050 car amp to a house system can it be done?

Yes it can be done. This doesnt mean that it should be done. First thing is finding a power supply to supply power to the unit. you would need to find the size of the fuses on the amp and finf a power supply to feed that power. All home theater systems have built in amps on them. It would be much simpler to find a home theater system to fit your need. However if you insist on this setup remember to find proper power supplies and wire the system with the proper gauge wire for the amp draw. No sense in burning down the house over it.

Where do i get the screws and power supply for it

The power supply is the vehicle 12V electrical system.

An amp wiring kit like this one should work OK.

Screws are any generic screws of the proper size, depending on what type of material you are mounting the amp to.

Hifonics 1500D started to hum through subs after beating on them. Unhooked rca's and not the sound. Any ideas?

Check power supply diods. power supply capacitors and power supply and output transistors.
Remember, distortion is the biggest killer of subs and amps. Everything made by anybody has its limit.

When i started to plug my battery in my amp made

you have blown the actual filters that make the sound. a amp is basically a filter with the same filters on both channels on each side of the inside of the amp - channel 1 and channel 2, that pop was in the heat sinks of the amp usually. if you have replaced the fuse in this amp and you get no on light, the internal amp is in need of repair

No power seaworthy marine amp 400

Do you have anything plugged into the "REM +" slot on the power side of the amp? You need either a signal from a Stereo head unit or another power source to get the amp to actually turn on. If you are using a switched setup for the amp, you can make a little jumper from the Batt+ to the REM+. It doesn;t draw anything significant, it just needs power to signal the amp to turn on. If you aren;t using a headunit, make sure that you wire in a switch inline between ther power source and the REM+ port on the amp, otherwise, the amp will be on all the time.

Legacy 1470 smoke prob.

If it begins to smoke with only the B+, ground and remote connected, the power supply transistors have likely failed.

The protection light generally won't come on if the power supply is blown because the supply must be working for the protection circuit (which protects the output transistors) to engage.

The power light may be connected to the B+ side of the power supply. If that's the case, the power light will illuminate even if the amp is inoperative.

Let me know if you have any other questions.

Blown fuses

This is a sign the you have poor voltage regulation. Which may mean that you are taxing the electrical system of your vehicle. I would suggest you adding a secondary electrical supply for you audio system. This can be done by adding an extra alternator and voltage regulator and battery supply. This will allow you to drive your audio system without having it (power supply) split between the vehicle and the audio system. The fact is your system is drawing to much current for the unit and your vehicle. You are blowing the 20-amp fuses which means the the amp is creating a currnet draw which is past the rated value of the fuses, which if done too many times could damage the power amp components in the unit. I would also check the ohmage reating on the speakers connect to the unit since you may have the wrong impedance which may also cause excessive current draw and actuate some sort of overcurrent protection.
