Hi, Anonymous and the usual suspects are:
Leaks are the most common sign of water pump failure, but what type of seepage are you seeing and what does it mean?
A coolant leak coming from the weep hole is a sign of water pump bearing or seal failure. This weep hole often resides between seals that separate the oil side from the coolant side. A small amount of "dry" seepage around the hole can be considered normal, but it's only a matter of time before a seal becomes defective and the seep turns into a drip. A coolant leak into the front cover area, connected to the oil sump, means the outer O-ring has failed. This could mimic a head gasket leak.
Adding cold coolant to an overheated engine can cause thermal shock and create a seal leak even in a new water pump. Starting an engine during a water pump replacement before adding coolant could have the same effect. Look for a crack across either the seal face or the mating ring as evidence.
Allow an overheated engine to sit and cool before adding coolant. Then, restart the engine and allow it to run while slowly adding the remainder.
Abrasive particles accelerate water pump seal wear. For example, systems that are not properly pressurized allow air to enter and foster the build-up of rust. Or, if water with a high mineral content is added to the system and is heated, it will begin to form deposits that will accumulate and cause passage restrictions. Both of these are harmful to seals.
Although rust is difficult to remove, it should be flushed from the system as thoroughly as possible before the old water pump is removed.
When replacing the pump, O-rings need to be lubricated with either oil or coolant. Do not use silicone or other sealants that can block the weep hole.
Cavitation is the formation of vapor cavities in a liquid as a result of forces acting upon the liquid, like rapid changes of pressure. Cavities form when pressure is relatively low, and then when subjected to higher pressure, the voids implode and can generate an intense shockwave. What's this mean for a water pump?
Water pump efficiency can depend greatly on the impeller and housing design. If there is excessive turbulence as a water pump impeller circulates through coolant, cavitation can occur, which hurts pumping efficiency and can cause further erosion of the impeller and impeller housing.
Water pumps serve as an idler pulley on many engines equipped with timing belts and, due to accessibility issues on many transverse engines and the labor operations involved in replacing the timing belt (especially on imports), it's cost-effective to invest in a new water pump as well, especially if the pump is near the 100,000- to 150,000-mile recommended replacement mark.
Water pumps can sometimes support a mechanical fan. If the fan assembly falters in some way, like from a bent fan blade or a severely cracked assembly, bearings can be affected. For evidence, look for casting breakage around the bearing support as this is typically caused by excessive vibration or an imbalance caused by a badly worn fan or clutch. To remedy, inspect the pulley, belt alignment and fan/fan clutch assembly, replacing any bent or worn components.
Blue discoloration of the water pump shaft would indicate excessive heat buildup for some period, eventually ending in breakage of the shaft. This heat buildup can be caused by the tremendous centrifugal forces created by imbalance, which overloads the bearing and generates a ton of heat. A clean break indicates an "instantaneous" fracture caused by sudden overload or imbalance at the bearing.
To remedy, check the pulleys for proper alignment, straightness and fatigue. Inspect fan/fan clutch assembly for a bent or damaged fan, a worn spacer, or a worn or damaged fan clutch.
Noisy shaft bearings are the second-most common reason for water pump failure. Most shaft bearings fail due to normal wear in the bearing or due to the normal oxidation of lubricant on the bearing surfaces. In rare cases, bearing failure can be hastened by over-tightening conventional accessory drive belts.
The less common water pump failure is the impeller slipping on the water pump shaft. A good water pump impeller will cause the pressure to increase as the engine is accelerated. If pressure does not increase, the impeller is slipping on the shaft or is missing impeller blades. In general, a good water pump should develop at least 10 psi of pressure above 2,000 rpm.
Since the impeller and shaft are a press-fit assembly, slippage occurs most frequently on remanufactured water pumps. In any case, ­slippage can be intermittent in nature and can depend greatly upon the temperature and speed of the engine.
Some replacement impellers can be manufactured from inferior metals that are susceptible to rust corrosion. In most of these cases, impeller blades begin to break away from the impeller due to a rust-through condition, which results in decreasing pumping capacity and an increasing presence of rust contamination in the cooling system.

Output voltage is based on 3600 rpm @ 60Hz. Sounds like your generator is over speeding slightly. Put a Frequency meter on the output of the generator and tune it to 61.5 Hz, that will get your generator in the 3600 RPM range.

Is the keyboard corded or wireless? If it is corded please check the cord for damage and the connections for dust. If the keyboard is wireless please try replacing the batteries unless the batteries are new. If they are new verify that they were installed correctly. Also make sure the keyboard is turned on. Please let me know if there is anything else.

Hi, Duane and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting/leaking, spark plug cable connections loose check for spark leakage in the dark.
6. A faulty ignition coil or electronic control module.
7. Faulty pulse coil.
8. Faulty CKP, CMP, or BAS sensor.
9. Faulty ignition switch.
10. Faulty run/off switch
11. Tilt sensor needs a reset.
12. Security alarm failing to disarm needs reset
