You posted under EH40 240Volt programmable timer.

If I understand correctly, you are testing the terminals when timer turns ON?
Test shows 120V between terminal 4 and ground wire.
Test shows 0 volts between terminal 6 and ground wire.

Test terminal 3 to ground -and- test terminal 5 to ground and make sure each tests 120V.
Test terminal 3 to terminal 5 for 240V.

If terminals 3 and 5 test correctly, but terminal 6 never has power, then relay inside timer has gone bad.

99 S10 battery check good 25% life left though 14.5 volts when running ran it about 30 min Battery reads 12.66 seams to repeatily drain till dead

replace the battery
battery cells will give a good reading until a load is applied then they fail quickly
for example a battery will read 12 volts or better in a static state but when a load is applied ( cranking , lights etc) the voltage will fall to 10 volts or less
the 14.5 volts you are treading is from an working alternator
the proper way to test a battery is with a load test machine
take the car to a battery shop and have it tested properly and while there have them replace the battery using ther standby battery that keeps all the radio codes and ecm memory operational

Have no power when I turn on ignition. battery is fully charged

Have you load tested the battery? I understand you have a 12 volt reading, but that means nothing if no load has been applied during the reading. It sounds to me like a bad battery...

Precor efx 546 error.

please follow this steps and fix it. God bless youError 43 - Zero Switch not FoundDescriptionThe C944 and several versions of C96X used a lift position identification system that did notutilize a potentiometer.Instead, it utilized a switch that would be physically actuated by the lift when the lift was in thezero incline position. A revolution sensor counted lifted motor revolutions to determinesubsequent lift positions. In addition two limit switches where used to remove power from the liftmotor if the lift moved outside of it's normal range.When the unit was powered up the lift would start to hunt for the zero switch. It would first go up4% (maximum lowest physical position was -3%) if it did not find the zero switch or it hit the upperlimit switch, it would then go down until did find the zero switch. When the zero switch waslocated it would stop, the system would then know its physical position and be prepared tomonitor the revolution sensor. If during this power up procedure the zero switch was not found anerror 43 would be displayed.Possible Causes1. The lift position actuator does not physically operate the zero switch.2. The lower PCA is bad.3. The zero switch is bad.Possible Remedies1. There are several physical problems related to the lift platform mounting or the plate the zeroswitch is mounted on that can cause the actuator knob to miss the zero switch as it movespast. Repair the lift platform mounting, repair or replace the lift switch mounting plate asrequired.2. The lower PCA provides a 5 VDC power source for the zero switch. You should measure 5VDC across the zero switch when the zero switch is activated. If the reading is significantlylow, remove both wires from the zero switch and repeat the measurement across the wiresremoved from the zero switch. If the reading is still significantly low, verify the zero switchwiring. If the wiring is intact and correctly connected, replace the lower PCA.3. Move the lift to position where the zero is switch is not activated and remove power from thetreadmill. Remove both leads from the zero switch and measure the zero switch with anohmmeter. The zero switch should read very near 0 ohms. While measuring the zero switchwith the ohmmeter, activate the switch by hand, the reading should change to infinite (open).If either of the above readings are significantly incorrect, replace the zero switch.

What's your problem?PRECOR EFX 546 ERROR CODE 43

Precor Error 43, Zero Switch not Found Probable Cause 1. Bad rotation sensor or missing magnet.
2. Lift position actuator does not physically operate the zero switch.
3. Bad lower PCA.
4. Bad zero switch.
Corrective Action
  1. Inspect for presence of magnet in the magnet holder. Replace magnet if missing. Check for output of the rotation sensor and follow signal all the way to the upper board. If the sensor has no output, replace. If the signal drops out at the cable, replace the cable.
  2. The lift platform mounting or the zero switch mounting plate could have physical problems that could cause the actuator knob to miss the zero switch as it moves past. Inspect and repair the lift platform mounting if necessary. Inspect and repair or replace the lift switch mounting plate if necessary.
  3. 5VDC is provided to the zero switch from the lower PCA. You should get 5VDC across the zero switch when it is activated. If the reading is considerably low, remove both wires from the zero switch and retest for voltage directly through the wires. If the reading is still considerably low, investigate the zero switch wiring. If the wiring is good and connected properly, replace the lower PCA.
  4. When a zero switch is bad or not actuated, the system will go through the entire search process and continue passed the home switch to find the lower limit switch. Move the lift to a position where the zero switch is not activated and remove power from the treadmill. Remove both wires from the zero switch and check the zero switch with an ohm meter. The zero switch should read near 0 ohms. While the ohm meter is still connected to the zero switch, activate the switch by hand and the reading should change to infinite (open). If either reading is considerably incorrect, replace the zero switch.

All lights and ignitors on my GE ZGU385N (Gas cooktop) stopped working all of a sudden. I checked the input voltage to the transformer and all looks fine so I know the issue is not with the outlet or power...

Disconnect power and set you meter to ohms. Check the both the line side and the low side of the the ****** for continuity. If you cannot get a reading from either side then that puppy is bad. More than likely that is gonna be it since everything quit. If it was the igniter box you might have weak spark etc. I thnk that transformer is your prob.

As reported before, there is no power in interior,vehicle will not start.,battery is fully charged. there is 12 volts at battery , and at starter relays bottom terminai,no voltage at top terminal....

check for corrosion on the large positive wire that leads to the starter. allthough you have 12 volts, but corrosion cant handle amperage. or it may be possible that you just need a new starter, you can remove the starter, and apply a seperate power source like a jump pack or seperate battery to verify that the starter is ok

Low oil presure

perform a master oil pressure test. this is done by removing the oil pressure sending unit and installing a oil pressure gauge. if the reading on the test gauge is ok, the sending unit needs to be replaced. if the pressure reads low on the test gauge, there may be excessive bearing wear or you may have worn valve guides. good luck!

No heat, and my drum is cracked, too!

Measure the voltage (with a voltmeter) at the two slanted slots in the dryer power plug which should read ~220 volts AC. If at or near zero, there is no power from the breaker pair in the house electrical panel. Go to the panel and push the breaker pair to off, then on. Recheck the dryer socket again. If still zero reading, one or both breakers are bad (assuming that you didn't plug the dryer back in after checking the voltage). If you did, remove the dryer plug, reset the breakers as before, and recheck at the socket once again. If you now have voltage, suspect a short circuit within the dryer--likely the heating element. You will need to remove the drum to access the element area. Make sure that the entire air vent area is open and clean the filter in detergent and hot water. Replace the drum if it is catching on clothes
