With the engine running, connect a dvm across the battery, in high idle, your meter should read 13.5 to 13.8 VDC, indicating proper operation of the charging system, if your meter reads, battery voltage or below, it is most probably your voltage regulator, which is located on the right side of the engine, it has 3 wires connected to it, one of the wires is violet, it is easily seen, there is a raised number on the item, it is attached by one 1/4 x 20 x 1/2" bolt, easily removed, contact a kohler dealer and read the number to them, ensuring that you purchase the correct regulator.

I had same. Flywheel magneto is the charging system. Turned out the magnets under the fly wheel are glued in and all fell out. Pull the flywheel, important to mark the order of the magnets, sand and clean each magnet and inside of flywheel then epoxy them back in (JB weld worked for me). Replace it all and done. Otherwise a new flywheel and coil set will run you about $500. It's a pain getting it all apart, and you need a wheel puller to get flywheel off , but beats the alternative!

When you remove the battery it will break the circuit and die and if your battery dosen't have at least 5v in it it won't charge and you will have to replace it.

Charging problem

Battery discharge when shut off is due to a connected add on in the truck,( 2way radio, some item plugged into the power plug, ETC). Also a bad battery will lose it's charge when not being charged,( I've seen brand new batteries do this, Have it load tested, Also the alternator can discharge the battery if the diode is defective. Depending on wiring set up the engine can shut off when you disconnect the positive cable.

Checking your alternator

On most cars and trucks, if you have a problem with the battery dying, the way to check if your system is charging, or your battery is bad, First: start the car, then loosen the negative battery terminal, then remove the terminal. If the car dies, then remove your alternator and have it tested at Auto Z or Advance. If the car still runs, remove the battery and have it tested. This works on 99% of cars trucks, and most engine driven vehicles, there are some imports that this will not work on due to engineering by the country that makes the vehicle.

01 Ford escort will only start and stay running with a jump box As soon as we take the positive cable of the battery the car will die Could it be the 100 amp fuse

Strange one? The engine dies because you have removed the battery supply. This leads to question the battery fitted on the vehicle, it sounds like it has no power at all (open circuit). Charge the battery and test that it can hold a charge. Fit another battery to the vehicle and see if the same thing happens?

The altinator is missing ground, any time you remove the battery and the engine dies, that only means that the altinator is not charging, there has to be a fuse for charging systme.

Wont start just clicks, battery is 1 yr old, dials go crazy when trying to start it

It is possible your alternator has died. Try charging the battery or getting a jump. Once the engine is running remove the Neg. battery terminal. If the engine dies the alternator is bad. If the engine continues to run it is probably your battery. Also if you can get it to a chain auto parts store (like autozone) they ussually check charging systems for free.

Battery Drain

It sounds like an Alternator problem.
Remember the Battery only Starts the vehicle and runs nominal operations. The Alternator actually provides the electricity to run the Engine operations. With that being said: Start the vehicle, jump start it if you have to. Remove the Negative Cable from the Battery or remove the jumper cables. If the Engine dies after doing this, the Alternaotr is bad and needs to be replaced. When the Alternator begins to die, it starts draining the Battery. During normal operation it is the Alternator that sends a small trickle charge back to the Battery keeping it charged-up.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at!

1) Battery dies while car sits overnight. Brand

check the ground to battery and clean posts if need be, also make sure that the alternator is at proper charging rate. a fully charged battery with engine off should read at least 12.5 or higher. when running the battery should read 14 volts or a little higher. clean corrosion from case also if need be. if the above does not work check engine ground.
