Title: what are these?
Post by: FeelixTC on January 11, 2014, 04:43:44 PM

Trying to get my old Lima Skinhead running better and while it's apart, I thought I'd ask if anyone knew what the two black gizmos are that are soldered in between pickup and motor. I've seen other skinheads 'undressed' and have never seen these.

Sorry this is in the wrong place, I'm uploading from Blockbarry and I need to be somewhere on Wednesday.......

Thanks in advance
Mitch

Probably a choke in series for suppression. Can be used instead of a parallel capacitor.

Thanks Malc - even without the pic! (Total upload failure :veryangry:)

..............So, do I need 'em? What are they there for??

Without measuring them, it is entirely possible that they are dropper resistors and the loco has a 6v motor, not a 12v, so I would leave well alone.

They are not original and have been added by someone - I'd remove them...

Cheers,
Alan

Thanks Doc, that was exactly my (uneducated) opinion.

They'll be gone shortly.

They look like suppression chokes to me.
