Resistor?

[wombweller]

Hi

Looking for help firstly identifying the component in the photos that I believe to be a resistor.I'm not sure what type of resistor this is but it's purpose from the object it came from is to spark quench.

The item in question has the name BERCO and 225ohm on it.

The resistor does not test when doing an ohm test so I believe it to be dead although it look fine.

I would like to replace this with a like resistor so if anyone can help point me to a supplier.

regards!!
Mark

hi Mark,
Are you sure thats not 2.25R..?

It is a wire wound resistor which generally has a higher power rating.
Here is a link (only so you can see pictures) of several types.
Generally, the higher the power rating, the larger size of the resistor.

hi Mark,

EDIT:
Gently crack the resistor coating with a light hammer so that you can partly expose the winding.
It will the be possible to measure a section and get an idea what the value really is.

Hi Eric

I'm pretty sure but not 100% other people that have these clocks are saying around the same value.
The resistor came from an old clock that has two large electromagnetic coils that run on around 20v.The resistor is for spark quenching on the contacts that switch the large coils.

Hi,
Did you see my edit about cracking the enamelled covering.?

Eric and PatM thanks thus far.

Can they be purchased with an hole through the center so I can fix it in place as it should? or old stock of the specific type, is this a long shot?

Cheers

Cheers!! will do this once I've identified a possible like replacement as if I end up having to get something similar then a will keep the old one in place and disguise the new one somewhere on the frame.

Cheers

Tubular power resistors generally have a hold in the center and can be secured with a bolt.
There should also be insulators on each end where the head of the bolt and the chassis would touch the resistor body.
