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 am not sure what you mean by "Have power going through the whole block." You will have to supply more information on your engine, as there are many different kinds of magnetos, and they work different ways.

Kohler courage 6.5hp wont start?

Could be a short in the coil for the sparkplug. Check the magneto- pull the plug wire off the spark plug and hold it close to the frame of the while someone tries to start it. Keep all parts of your body clear of the mower- only hold the sparkplug wire. When the motor turns over, verify spark from the wire to the frame. If no spark, you likely have a bad magneto coil. If you have a good spark, try taking the air filter off and use some engine starter fluid (not much) and then try and start again. If it starts and runs for a second with the starter fluid, you probably have a problem with your fuel not getting in, which leads to troubleshooting the carb and intake.

Change a lawnmower sparkplug wire


You will need to buy a replacement magneto as the secondary (spark plug wires) are hard wired into the magneto.

if you spark a little starting fluid to it does it fire?if so then fuel is the problem then is the gas older than 30 days dump it out and try fresh gas if new gas then open the carb and clean it if it does not fire on starting fluid check for spark if no spark pull the top cover from the engine and look for wiring damage unplug the coil from the engine side of the coil and check for spark if no spark then the coil is bad and if its a riding mower the carb might have a anti back fire valve that could stick closed

Dell xps 420 computer will no start blinking amber light no diagnostics lights working

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location, if applicable.
Ensure that the processor power cable is securely connected to the system board.
This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.
