Question about Hitachi EC12 Portable Electric 2hp Air Compressor, Oil Lubricated

2 Answers

My Hitachi EC2 AC has "died". It is as if it is not plugged in. No response from tripping switch. Removed cover to be sure connection tab is pressed. Nothing. Was running OK, but it just stopped. It has been well mantained and no problems for years. To summarize, it just stopped as if unplugged. Verified power is at switch. Advice is appreciated. Pat Patrick

    Good advice. I checked current continuity to motor. Seems OK. No burnt smell at motor. Suspecting capacitor(s). Will test tomorrow and advise. Thanks.

Hi, First thing to try is to switch off EVERYTHING and then switch them all back on one at a time. If there is a faulty appliance then as soon as you switch that one on the sockets will 'trip'. You can then have a look at that device to see if you can see a problem. OR If you have the RCD trip with a push to test button or a circuit breaker that protects individual circuits? The RCD will trip on live faults to earth. The circuit breaker on live faults to neutral or earth. RCD?s are sensitive to moisture. They are often set off by washing machines and steam irons as the amount of moisture in the appliance can be enough to cause a live to earth fault. Only way to be sure is unplug everything and plug stuff in till the trip goes out. As we are dealing with sensitive equipment it can take a while to figure out. If it?s down to cold, damp weather try turning the heat up a bit. OR If I could test the circuits with an Insulation Resistance Tester I could probably tell you straight away. You might have to get a sparky in.

Can you check the motor if it has a burnt smell on it? If you do..you can have this re-wired or rewind. Also check the "starting capacitor" (located near the switch box)..have it tested if still working or has a continuity on it. Check also the power cord status if it has a disconnected portion on it.

I hope that the steps information above would help resolve the problem. Please feel free to contact me again if you will require further assistance. tnx

Fan Will Not Run


There are several reasons why a Maxim-X fan might not run. One reason might be that the fan fuse has blown. The fan has a 10A fuse all its own which is located under the cover for the indicator lights by the ignition keyhole (there are four #2 Philips screws that need to be removed before the cover can be removed to access fuses and indicator bulbs).

If the fuse is OK, then the next possibility is that the 'Thermo Switch" which trips the fan isn't making a connection. The Thermo Switch is threaded into the thermostat housing and has a push-on wire connection. Actually, the temperature sensor is also threaded into the thermostat housing but it is the smaller of the two sensors/switches. The larger of the two, which I believe is accessible from the left side of the thermostat housing, is the switch that trips the fan. Often the push-on connection gets oxidized and needs cleaning. Often the wire connection becomes loose and can simply be tightened and pressed securely back into place to restore the connection.

Another reason the fan might not spin is that the power connector has a bad connection. From toward the right side of the fan you'll see a short length of wire (maybe a foot) with two conductors leading to what I seem to recall is a red plug. Like all the other plugs, that can oxidize and create a bad connection. The plug can also come loose if someone before you has broken the locking tab or maybe didn't plug the two halves properly together again. You'll find the plug end up around the right side of the thermostat housing.... between the thermostat housing and the right frame rail. That's also where one white and one yellow plug are tucked away (the yellow is the power plug for the left coil and the white is the power plug for the right coil). It's a pretty tight cluster of wires and plugs but finding the red one for the radiator fan power is fairly easy because tracing the wire back to the fan is fairly easy.

So, if the fuse is OK and the thermo switch is working, and the connection from the thermo switch is a good one, and the power connection for the fan is solid.... then the fan might be burnt out. If so, they come up on eBay often enough so it shouldn't be too difficult to find a replacement.

But, from my experience, my money is on the fuse first, the bad thermo switch connection second and possibly a failed thermo switch third. That's what I've seen most often. Whatever it is, it's a reasonably easy fix.

Tip

In order to replace the bulbs,the headlight assemblies need to be removed from t


On late model LINCOLN TOWN CARS In order to replace the bulbs,the headlight assemblies need to be removed from the car.The following instructions make it easy.
The grill has a top cover with clips that are unscrewed.There are about 6 of them.After cover removal,remove the headlight assembly by pulling up on the two metal tabs on each light assembly.or on some 2005 and newer models the few bolts holding in the light assembly.There is an access hole for a 1/4 inch extension to fit through for the bottom bolt.The bolts are 8mm.Then in the middle of the light assembly there is also a plastic tab that must be pushed down with a screwdriver and then the light assembly comes out.Once the electrical connectors are unplugged,the headlight assembly can be removed from the car ,put face down on a towel and disassembled so that the bulbs can be replaced.
The older versions have plastic tabs holding the back covers on,and the newer versions have T 27 torx screws holding the covers together.After the back cover is removed,you will see a collar that holds in the electrical socket that connects to the bulb. mark the collar position with a felt pen.Rotate the collar counterclockwise to remove it.The bulb and socket are then separated and the new bulb installed.Make sure the collar goes on first,as it will not slide over the bulb,only the bulb connector.Seat the new bulb,install the plug onto the bulb then the lock collar and reinstall the back covers.Do not touch the glass bulb surface with your fingers,as the oil will cause the glass to shatter when hot.Handle the bulb by the base only.
Before installing the light assembly into the car plug in the main connectors and check that the light works. If all is o.k., re-install the light into the car.After that, check to make sure that the lock tabs are all in place.Re- install the grill cover and the clips.Make sure that the hole in the grill cover on the driver's side goes over the hood switch for the alarm properly.Check final operation after re-assembly of all pieces.

Manual for replacing lamp for 60v500a


1. Turn off the main power switch and unplug the power cord. Wait at least 30 minutes to allow the lamp to cool down before
replacing it.
2. Remove the front cover from the TV set. This is held by a snap on. Pull the front cover outwards until the quick snap on
disengages.
3. Remove the screw securing the lamp cover with a Phillips head screw driver. Remove the lamp cover.
4. Remove the two screws that hold the lamp in place. Remove the lamp unit by holding the lamp handle, then pulling outwards.
Exercise caution when removing the lamp unit to avoid injury to your fingers.
5. Replace with the new lamp.
Place the removed lamp into the empty box of the replacement lamp. Do not touch the front glass of the new lamp or its
receptacle. This may shorten the life of the lamp and reduce the picture quality.
• Push the lamp unit back to its original position.
• Tighten the screws firmly on the lamp unit. If they are loose, the TV may not operate correctly.
6. Without installing the lamp cover, the power will be off and the Lamp Indicator will flash. Be sure to install the lamp
cover by re-engaging the two clips and tighten the screws before turning the power on, otherwise it may cause unusual colors.
7. Install the front cover. Put the front cover back in and align the snap on quick connect then push inwards holding
the left and right side of the front cover until you hear a snap. Push the other snap on gently to make a good fit.
8. Plug power cord into AC outlet and turn on the main power switch.
NOTE: The lamp in this product contains Mercury. Dispose of properly in accordance with applicable environmental
laws. For Recycling and Disposal information, contact your respective governmental agencies or the
Electronic Industries Alliance at www.eiae.org (in the U.S.) or Electronic Product Stewardship Canada at

It would appear from what you say, there is a short on the motherboard. This can cause the adapter to shut down, which it is suppose to do. Unless there is an object in the laptop, the motherboard is damaged and must be repair/replaced.

Hitachi EC12 AC is "dead"


you should take the cover off where the pressure switch is (the on off switch) and see if any wires fell off the connectors. the white wire should go straight throu to the motor, then the black wire will go to the switch than the pressure switch then to the motor. if you are careful enough you could temperarly straight wire the black wire from the cord to the motor wire.

Trips when plugged in


AC pulling to much power from outlet. Thus tripping the switch.
try to remove all that is plugged into this outlet and have only the AC plug into the outlet.

If you live in an apartment, there might be a dedicated plug for AC. Ask the super.
