Megger Model SL series1,2.5KV/5KV - UK Vintage Radio Repair and Restoration Discussion Forum

Hello Folks, There is a post in "Information & Service Data Wanted" concerning these huge big Meggers, which I've replied to.
Does anyone know anything about them & possibly hold some spares ?
I only aquired mine yesterday, but definetely need some help & advice. Mine is possibly a later hybrid model, as its plated "THORN EMI" & not "Evershed & Vignoles". Unfortunately the handle shaft connection to the big 3"dia paxolin cogwheel is missing.
The beautiful m/c meter has a wee circular spirit level inserted in the middle.

Regards, David

Belay that last pipe - as they would say in the Navy. Winding shaft connection - found. Jammed underneath the motor mechanism, looks like the two wee grubscrews had come loose. However, the internal 115V motor's spring loaded start/run switch is missing. Will definitely need one of those.
Have been trawling through the internet sites, but havent found a manual yet.
This thing is magnificently well built electronically, and the joinery work in the casing is lovely.

Regards, David

David,
You're a braver man than I am Gunga Din!
I've been bitten by my 500v ones and it's not pleasant.
Good luck and be careful.

Peter, Great photo of your manual model1 2.5KV. However, its totally different than this manual/motorised version I have.
Alan, have carefully AVO'd this beast on it's ranges from 500 to 2500V. All is fine, including my fingers.

Regards, David

Have delved further. It would seem that the Evershed & Vignoles Series1 Megger Insulation Tester is the item shown in Peter's picture. ie - of 1950's vintage, hand wound.
Mine - the SL Model Series1 Megger Insulation Tester is a much later production from THORN EMI, incorporating 1980's circuitry, hand wound or motorised. Have looked through Mauritron & BAMA, but nothing on a manual.
The 115V motor has a part no = 6230-444 and it's start/run switch is what I must aquire somehow.
Meantime, shall rub down & re-varnish the lovely wooden case. It works perfectly in its hand-wound mode, so can still take pride of place on my shelf.

Regards, David
