Internal fuse what is the value

I am sure the battery is not internally fused, but I have opened many akin to it and there was no fusing in the battery (I repaired many radios and the fuse was always in them).

NNTN6034A 4150 mAh Li ion IMPRES Battery

An ampere-hour or amp-hour (symbol A·h, A h, Ah) is a unit of electric charge, with subunits milliampere-hour (mA·h or mAh; often used in rechargeable and disposable battery specifications) and milliampere-second (mA·s).
An ampere-hour is not a unit of energy. In a battery system, for example, accurate calculation of the energy delivered requires integration of the power delivered (product of instantaneous voltage and instantaneous current) over the discharge interval. Generally, the battery voltage varies during discharge; an average value or nominal value may be used to approximate the integration of power.

please check for any blown fuses, if there is replace with the same value, do not replace it with a higher value. also check resistors near the rectifier diodes, check full wave diodes & ic regulators, if you find an error replace with the same value or specs.

Do NOT replace fuse without repairing the CAUSE of it blowing. Fuses blow as a result of excess current being drawn. They protect from further internal damage. They can blow because of an internal failure or because the inout power is outside of the specified value...ALWAYS check your power source. Always power all interconnected equippment from one receptacle or power source.

I have the same VOM RCA WV-547A and i need the resistance value part because it's burned.

It is NEVER a good idea to increase the values of fuses . Chances are you have internally damaged your amp. The next time you are faced with this problem you need to find out why your amp is blowing fuses and not keep changing the value of the fuse.

The manual indicates there is an auto-reseting thermal cutout that turns the motor off if overheated.

If there is an internal fuse that has blown, there LIKELY is other damage that needs to be addressed. A fuse will have markings on it for the value. An appliance repair part outlet should be able to supply parts for this unit.

it is marked on the fuse---amps and voltage--some of the fuses these sets use are special---don't buy it at radio shack---also the values for the fuse are usually printed on the circuit board under it.

It is common for manufactuers to label the fuses on the circuit board as to their values. If they are not labeled there you can try contacting the manufactuer or looking in your manual. You can tell if they are slow or fast blow by the internal wire, if its thin and straight its a fast blow, if its thicker and spiraled its slow blow.

Any internal slow-blow fuse can be replaced with one of the correct value. Fuses do seem to have a finite life, so occasionally you can just replace the blown fuse  with an identical one and all will be well. However, fuses are protection devices , and it's more likely that you have a  short circuit or  defective component in your VS3251 that's causing it to draw too much current , and the internal fuse is blowing to prevent further damage. ie the fuse blowing is the symptom not the problem. Never replace fuses with ones of a higher current rating. Slow-blow fuses have the suffix T (for "Time Delay", and normal ones have F ( for "Fast"). With the street price of the VS3251 , a commercial repair is uneconomical

Hello sjday62

It sounds as if you have a component that has changed value enough in value to cause a high current draw, but has not completely shorted out. this phrase from you "so I did a stupid thing and bypassed the internal fuse and it turned on and worked" Not as stupid as you would think because it confirms what I said above, the 6.3 amp fuse tells me that the current draw normally is about 3 amperes since the normal rule of thumb is to double the value of the current to select the type of fuse. a five amp fuse should as well as a 4 amp fuse (it's best and recommended to use the exact fuse type). Now back to your issue. I would suspect that a transformer in the power chain has developed a shorted winding, or a capacitor begun to develop a short or excessive absorption.

I would suggest that you have the set looked at by a qualified TV technician.

I hope this helps,

Thank you,
