SOURCE: power inverter

Most likely a fuse. Check for a fuse on the inverter itself or one inline with the plug. Usually you can screw off the tip of the plug and replace the fuse inside.

SOURCE: No power output from my vector 1000w inverter.

Buy a different brand of inverter. Yours has developed a short which the protection circuit is catching. It then tries a restart but fails all over again. Most likely o/p short which looks like an overload to the inverter.

SOURCE: my vector power inverter needs to be reset

Inverters use high power transistors to create an A/C voltage from a D/C input. These transistors are the common point of failure when the units are not cooled properly or used beyond their rated capacity. (Actually, you should always buy an inverter that’s rating for continuous use is well below what your actual need is). What’s most likely happened is that these have shorted out and need to be replaced. Unfortunately, replacement parts alone will likely cost nearly what a new unit costs.

Sorry to be the bearer of bad news; but you basically have a nice paperweight with some pretty lights and fans on it.

There are 8 40A fuses inside this unit. In the following pics you will see a bank of 4 and another bank with 3 of the 4 removed. I'm currently working on mine as it will cost me more to ship and have Cobra repair than I paid for the unit ($133 to repair). Good luck with your problem

How do I repair noisy tappets?

For tappets, you can try spraying GOOD quality penetrating oil down the pushrods to enter the top of the lifters, if they are hydraulic. If mechanical, adjust gap per your shop manual. Fan belt breaking can be due to misalignment of some pulley, or a driven device that doesn't turn easily (bad bearing).

Can i reduce the duct vent size

yes of course you can but if its because your getting to much air you can reduce the fan speed by just replacing the pulley or if it doesnt have a belt drive system it would be cheaper and easier just to install an inverter speed control

Diagram on how to change a water pump

It is driven by the timing belt. You must remove the radiator fan, drive belt or belts, possibly valve covers, the harmonic balancer, and then the timing cover. This is the time to change the timing belt and tensioner and idler as well.

2004 1.8t squealing once engine warmed up

Is this the accessory drive belt that is noisy? If so check the belt edge for frayed or exposed cords like a tire cord, if that is found you have a defective pulley Or a crank pulley that is moving outboard due to the harmonic damper coming apart, this causes the belt to not run true across the pulleys and that causes noise..

How to fix noisy fan in chef fan forced oven

Possible fault in the bearing bushes , in the first place you can spray a WD40 or even some light oil into the fan's rotor ends where the bearings are located. If the sound reduces clean and wipe off excess oil from the shaft side. Also make sure that the fan leaf is not making the noise due to any dirt accumulation or obstruction.

I just got back from a mechanic and he said that my fan belt is getting eaten up by the "harmonious" something or other on the bottom of the engine?? What is that??

A harmonic balancer (also called crank pulley damper, crankshaft damper, torsional damper, or vibration damper) is a device connected to the crankshaft of an engine to reduce torsional vibration and serves as a pulley for drive belts.

Where is the clutch fan located in my 98 pathfinder?

if the fan is belt driven the center pulley would drive the fan. the clutch would at the center of the fan and fastened to the pulley. Would be silver with fins on it at the center of the fan.

If it is electric (there may be models with electric fans) there would be no belts driving the fan. instead an electric motor at the center of the fan would do the driving. more horsepower due to parasitic load on the motor, but electric motor do seize up.

I hope i covered everything good luck!

That noise is due to your Power-Supply-Unit, Hard-Drive, Optical Drives, other spinning devices, and ventilation fans. You can reduce some of it but not all of it.

For example, your hard-drive could be rather old and producing a lot of noise when it spins up, reads, or writes data. You could replace it with a newer hard-drive which barely makes any noise. The same with your Power Supply Unit (PSU). It could be old and rather noisy. You could buy yourself a newer one such as the ones made by PC Power & Cooling which gets you a quieter product. However that's about it as you DO NOT want to reduce the amount of fans in your system.

Sorry if this was not the solution you were after. However most noise from a computer stems from ventilation fans which can be replaced but should not be removed.
