everest throddle control

So I'm back at trying to fix the rpm control. It NOT the toggle switch, its inside the module on top. If you remember 18 mo ago or so, I had JD fix it; that was good for 2 weeks. Ever since I've been tapping the module box to rpm up/down. So I recently find out my old mechanics is working on TMs!!!! He did work for me 20 years ago. He is some what new to it, but has some good resources he can reach out to.
Sooooo, there is a coil(spring? I don't know) inside that is broke/squished. Some supplier told him; "parts arnt available". Replace the whole assembly...$1500 wth! Talked with JD to see about parts.....
For right now, he is going to jerry-rig it so I can manually adjust it. And not have to keep tapping it.

Yikes, that is a very expensive part!

We all know that none of these companies are making their own stuff, so that part exists out there for other machines as well. You just have to find it.

Made by zeinith. Who ever they are.

It might turn up in the strangest of places....like a Yugo.

Is this just a drive by wire controller? Seems like that would be easy to find.

I can almost guarantee you it's not that simple Bob, I can almost bet you it's inside of his computer ( zenith unit is the computer ), the only chance you'll be able to find the parts is if you know exactly what you are looking for, which is almost impossible without taking that thing apart which is almost impossible because that zenith unit is like a fortress.
I honestly would rather keep tapping it or replace it rather than mess around with it and risking it not to work when you need it to work.

If JD fixed it and this is the same item replaced. I would talk with zenith and see if they will cover it under warranty.

I just read up on the system, ECU system.

Does the module feel hot when it malfunctions? That was the clue for most ECU module failures in the automotive world. Next time it fails to operate, spray it with a tilted canned air spray so the liquid propellant hits the ECU and chills it....see if it recovers.

I used to have overheat issues with my zenith in blue line Thermalwave due to the location of it ( on top of the motor under the top cover ), considering the guys that built them are engineers, it's mind boggling that they would put them there.
In my case when the computer gets hot, the machine would just keep shutting off, after I moved the ecu, I didn't have the problems anymore, I didn't have issues with throttle not going up or down or needs to be tapped, however Bob's idea is worth a try.
I believe your Ecu is on the left side of the motor ?

I have the panels off. It is slightly on the right side.
A spring/coil inside is worn out. So the magnet don't move when toggle switch is adjusted.

Makes my TNT seem like a good choice. I think I can repair things on it with a rubber band and some Bisquick.

Just got it back. Trying to find replamemt coil part from zienth. wish me luck).
Right now have small needle nose vise on it; very slight twist adjust the rpms and I mean a smidgen.

They must be able to help, it isn't like this was made by Ford in 1937.

The biggest problem with this industry is dishonesty, well may be with other industry too but I just see people don't want to sell small parts anymore, they would rather sell the whole thing to try to make as much $$ as possible, for example the shut off float thing, they ( local dealers ) used to sell the magnets ( $ 40 ) instead of the whole float ( $ 170 ), they stopped selling the magnets a few years ago.
That computer is around $ 1500 if I'm not mistaken, if you can get parts for it, you're blessed, get the parts as soon as possible before someone decided not to sell them anymore in order to sell you $ 1500 ecu.
Bob, I can see why people love TNT because of it's simplicity, if I started out with TNT, I would probably stick with it.

It is like all technology Dp, when it works it is amazing, but when it doesn't it is hell to trouble shoot and costly to repair. The TNT is all knobs and toggle switches that you can buy at the local hardware store for a few bucks. It is a primitive machine that is too loud, leaves you smelling like exhaust fumes, and many other small issues, but it is sure cheap to run and repair.

They don't sell small parts any more for the same reason that contractors don't want to repair anything, they always want to rip it out and start over.....it is easier and more profitable for them. To hell with the customer, they only want what is better for them.

The end user should demand different. We should all be demanding TM builders back up their equipment with available parts that can be easily sourced. Would you ever buy a car knowing that you will never be able to get parts for it?

Amen guys.
We recently had our well pump pulsating (its 35 year old +). Had a pump service come out and diagnose it. Old control panel, tank isn't holding air level(whole tank had water), and some relief valve that was 20' down the well. Would have to cut a hole in the well house roof, to pull the well pipe. And josteling around the pump might cause issues.
Basic stuff....$700
Add new pump and motor...another$1500.

My son did some research. Relief valve on top of tank was leaking air. He replaced that, put 28psi pressure in tank...bingo. $3 part.

Guess who I'll never use again? 1 strike and they're out. Even in baseball you can strike out with 1 pitch. https://m.youtube.com/watch?v=Bd47e0nOXl8

Update: first, my Gerry rig rpm control(pic). Wood dowel goes down-rpm goes up. Clamp holds rpm in place. Vise is clamped to control inside module.
My mech has been in convo  with zienth, new inerds=$800 P/L. I guest no vacation this year.
Another CC in town has Everests and mech has Been down this road.

That is pretty creative, but if it works, so be it. $800 for new guts for the gizmo (technical terms for carpet cleaners) isn't cheap, but if it solves the problem it is probably worth it. Murphy's law says that the farm-rigged set-up will fail at some point and since that means no machine....no money.

I think this is one of those times where you hold your nose and order the part.

Nice work getting that money maker nack.on the road.

I think my briggs is nearing the end of its life just like my van is. One of these days I'm going to take a picture of my van so you guys could see how badly it's leaning

Matt, is that a carb everest ?
$ 800 for a new zenith is really cheap, my thermal wave's zenith was $ 1500 ( before I moved it out of the heat zone ).

DP,
its EFI. That's just for the inerds. Not the whole module.
Yes, $1500 for new module from zeinth.
If you go thru Jondon, its $1800. Had to control from laughing when he told me $1800.

What JD did(from my understanding); was go in and clean up and lube any moving parts. Seems there is a magnut inside that moves when toggle switch is moved. So there wasn't any parts replaced.

Honestly Matt, I would fork the $ 1500, since that's an electronic part, and it's been exposed to heat day in and day out, new computer will give you a full warranty ? Plus it's a huge peace of mind going through this year and next.

So we finally got it done(well, almost)
Got to have some adjusting done for the idle- it dosnt idle. It Boogs down. So I start in 1 wand mode.
Going back tomorrow to get idle set.
So inside, the magnut sits inside a coil of copper wire. The copper wire was worn down.
I have the part, try to post a pic.
*so in 1 wand mode- its running like a champ. The wand was locking down on the carpet real good.

Its nice when the TM is sucking like it should How much was the part
I couldn't believe the starter for my TM was 140.00 when you can get one for 40 bucks for a car
