Has anyone modded their cibola with GB knob?

[amberjack]

I have them wired to 2 and 3 like the pdf says

should work then.. have you checked the switch function with a meter? with the meter connected to the "wiper"
and either of the other two terminals the resistance should either increase or decrease as the knob is turned. if the meter is connected to the two non wiper terminals the resistance won't change

It does work. Goes negative with ccw turn and positive with cw turn.
The issue is that I have to turn it to nine turns cw from all the way ccw only leaving 3-4 to 1 turn before reaching the end on cw turns.

so its working its just not perfect ?? you need to hop on the vanity fair like me just take it man it works what else do you need ?? you know it was worthless after you started fiddling I have seen countless modded Tesoro's no one wants them, so use it have fun find some gold

yeah taming the B2 is a bit easier the HOT's are a bit different.

remember keep that threshold low, sens at 9 ish and turn the pot with the detector still.

you'll work it out !!

Maybe he can ship it to Sven....

Or call Rusty.

Rusty will offer to return it to stock condition as they will not work on a modified detector.
I now live in Canada, no longer feasible cost effective to ship to me. Keith who originated the mod
has done many Cibolas and lives in Georgia, he can still do them.

This is just the classical scenario , quick easy mod gone bad?
When in doubt, stop while your ahead, have some one else do it, who has done it....
Everyone is warned about doing mods, be prepared for failure in some way, especially if this is a first time
project. Bet there are a whole pile of bad projects gathering dust............its also amazing to see called claimed educated
high tech electronics technician being over confident, work on a metal detector and be totally stumped as to why
its no longer working or why he can't get a malfunctioning detector working again, or even assemble a kit.
They may know electronics but, don't know metal detector circuitry.

I chalk up all my bad projects as a learning experience(s).
As always, I suggest most people should leave their Tesoro's alone. Unless you get one dirt cheap and if you mess it up, it won't matter much, you can get your $$ back selling parts,
or send it back to Tesoro for repair. Buy a Tesoro with the appropriate adjustment controls you need and want.

I'll just leave it as it. There's a chance its the coil to gents.
I have no idea who and how many owned this before me.
My troy seemed fine but when tesoro rested it, they said they were surprised it even worked at all.
So that's the other option.
Sadly, I don't want to spend any more on this one to buy a new coil or send it in. It works, and works well. Just have to be way up on the knob to set it neutral. But it does go neutral, so it's functioning.
I got a great deal on the detector and it was an accident anyway buying it. 25 for the mod parts.
The machine was running negative stock before I touched it, which makes me think it's the coil a bit out of whack.
I'll just use it for what it is. No biggie.
It is functioning. And well.

 

[Sven]

I did Mr. Bill's mods to my IDX.
There's a reason why these controls were pre-set by the factory and not user controls.
The extra controls do interact with each other. If you adjust one, you need to compensate by adjusting another.
It's no longer a simple turn on and go detector. If you know how to use the controls, its like a new and better performing machine.

 

[amberjack]

yeah I want one of those Sven

[Stoof-tabsallday]

I will say it does punch alot hard on signals now, probably because it was so off before the mod. I really punches on the signals now.

 

[amberjack]

tell ya something about wires I learnt a long time ago, now you need to listen as its very important they belong back in the hole some goose decided it was a good idea to liberate them from and all he achieved was to slow down my work and make more for himself, so I just walked around and pushed them all back in their homes so I could get my trowel over the joint and do a good job.

what's the moral to this story you know where to stick your wires.

I have them wired to 2 and 3 like the pdf says

should work then.. have you checked the switch function with a meter? with the meter connected to the "wiper"
and either of the other two terminals the resistance should either increase or decrease as the knob is turned. if the meter is connected to the two non wiper terminals the resistance won't change

It does work. Goes negative with ccw turn and positive with cw turn.
The issue is that I have to turn it to nine turns cw from all the way ccw only leaving 3-4 to 1 turn before reaching the end on cw turns.

I'd check the pot with a meter as to it's resistance.. If you are using a 50K pot you should get from Zero to 50,000 ohms plus or minus it's tolerance. you may have one that is not in tolerance or a different pot that is mis-identified. I If needed, more resistance can be added by adding a resistor, in series, to the pot

Ok I'll check that with my multimeter

When talking about a hobby, it's never talking shop.
Salt hough I'm at work in the die shop talking about my hobby.... so go figure.

that should help find the problem. with my Cibola the pot is set approx in the middle of the range of travel (4 turnes CW or 6 turns CCW). I have a counting dial on mine

Well considering I paid $26 from mouser and theyre pretty reputable, I'd hope they didn't sent the wrong on lol. Did my pic of which tabs I soldered look right to how yours is?

 

[Stoof-tabsallday]

Another option is to find a regular 3 3/4 pot and just put that in... there was another gent on here that did that. Something he didn't like about the 10 turn I guess.

mistakes happen.. they are only human checking it with your meter will tell. The pot I used is different than yours.. the "wiper" terminal on mine is located in the center..see pic

 

[Sven]

These are the 10 turn pots I use for my PI since finding them, they take less room inside the control box as the pot is for the most part external.

You can buy them off ebay from China.

It looks like you have 3 wires soldered, or at least there's solder on 3 of the tabs.
And you are on the high cw tab and the wiper?
Looks like you have the middle and the bottom tab soldered to wires, right? And the top closest to knob has solder on it or another wire? Haha im confused.
Also, I notice that your grounding washer is on your venter switch (lock washer welded to black wire). Mine is on one of my pots. Not sure if it matters, but just noticing differences.

Those look awesome!! So there are 3 of those prongs on there? One high, one low, and one wiper?
