johnrussell84 2,774 Posted January 17, 2016 Report Share Posted January 17, 2016 If u get a reply let me know mate ave got 4 boxes needing repaired, 2 I reckon are needing wheels and the bit underneath the other 2 maybe a wizard lol Quote Link to post
Arry 19,004 Posted January 17, 2016 Report Share Posted January 17, 2016 I think they are the variable resistors or preset vertical trimmer potentiometers. I've fitted these in one of my boxes, the one marked 1m is 1 ohm and the other is 100 ohm. i got them from Mallinson Electrical. Little tip change one then the other as easy to get muddled up as they look the same. They are adjustable to set your depth, us a small terminal screw driver and car full not to force.

The one 8,405 Posted January 17, 2016 Author Report Share Posted January 17, 2016 Im going to have a look later out of 11 boxes got 9 that work and cleaned up the other one the black wires broke off the battery terminal so I will solder on a new one and when my head stops buzzing im sure I will kill or cure the last one Quote Link to post

A guy on ebay sells them. http://www.ebay.co.uk/itm/Ferret-Finder-on-off-depth-switch-Deben-Terrier-Locator-/252255043836 Cheers Arry Quote Link to post
johnrussell84 2,774 Posted January 18, 2016 Report Share Posted January 18, 2016 Yeh mate I reckon that's what's 2 need problem is I'm shit at most things so would break it even more Quote Link to post
The one 8,405 Posted January 18, 2016 Author Report Share Posted January 18, 2016 Right I think that's what I've got with these 100R's but what I can see there under the depth wheel and vr1 &2 have 3 lugs for soldering in a row these 100R's have two at one side and the third at the other ? with my limited soldering ability this is going to be a miracle fix 1 Quote Link to post
deanflute 550 Posted January 18, 2016 Report Share Posted January 18, 2016 07951 286630 phone Dave on this number and have a chat with him. He'll point you in the right direction Quote Link to post
Arry 19,004 Posted January 18, 2016 Report Share Posted January 18, 2016 Vr1 and vr2 are usually blue in later boxes black and in the centre there is a slot for adjustment. They should have 2 legs in line and the middle 1 slightly off set a little so not quite in line. They are different values one of them is 100 ohms and should have two sets of numbers on it, one of the set should read 100. The other one will have 1m this means 1 ohm, So its 100 times less resistance. I bought 2 of each off Mallinson Electrical for less than £2. Cheers Arry Quote Link to post
Arry 19,004 Posted January 18, 2016 Report Share Posted January 18, 2016 On reading you post again you say "under the depth wheel" are you talking about the on/off depth switch? If so, I think but not 100% sure they are 5000 Ohms as the only marking i can find on the switch is B5K. K = 1000 so 5K makes it 5000 ohms. this switch should have five legs. The ones you have marked 100R are 100 ohms. I have bought them of the guy on ebay fitted them and they work fine. Cheers Arry Quote Link to post

maxwell 88 Posted January 19, 2016 Report Share Posted January 19, 2016 Is there any other suppliers for the switch, just in case the lad on ebay runs out as he seems to be the only one selling the switches Quote Link to post
