Well I couldn't help myself so I went out and stuck the pedal in the car and went for a spin, ( in my pajamas I might add),, one word----- new car.. OK Ktwo words but it is so different now, still need to learn the pedal a bit again but no burn out backing out of the garage. works very well,, glad this is now out of my way. I has really bothered me.

I got with Brian at EVA about my potbox and he has shipped a replacement PB-6 out as mine was still under warranty.

I'm glad I read your thread because that choppiness has been bugging the crap out of me.

I'm tempted to pull the dimmer switch out of the wall in the living room to test it out sorta like you did anyway just for fun.

I'm glad things worked out, but those potboxes aren't cheap! Something seems wrong with this picture.

will a dimmer switch be the right resistance?? Heck the pot I got at radio shack was 3 bucks.

The PB 6 is not very impressive (IMHO) mine is only 2 cars , 1 crash and 6 months old,, heck ya should have just asked for the pot part that would be a 5 minute swap out,, also what I like about mine is it is easily adjustable by rotating the pot from behind ( the main part) I am still tweakin a bit but when I am done I will lock it in place with fingernail polish. Adjusting the PB 6 precisely takes a bit of effort.

drove 20 miles today on the car now charging. It is nice that it is so smooth. I am curious as to why the first pot went bad,, but very glad it wasn't the controller,,,,AGAIN. The new controller has woked just awesome by the way. The squeeling part has pretty much stopped on it's own for what ever reason.

not cheap at all,, a waste of money in my case. I like the added resolution I now have as well. the acceleration it completely different now, partly from the new pot and partly from the resolution I am sure.

Here again just another opinion about charging deep cycles,, I really think this is a problem I have currently, I have 4 different chargers now that I am playing with , they all seem to work well but I do have a favorit , I will post more on this later.

". Battery Cycle Life

Like a NiCad battery, a deep cycle marine battery must be "trained" in order to do its job at maximum efficiency levels. Let me give you the guaranteed recipe for disappointment. Take anew, fully charged battery and discharge it slightly. Then, put a light charge on it to top it off. Do that several times in a row and you now have a great big battery with nearly no usable power. The battery has been trained to have a shallow charge memory. Weird, but true. For best results a deep cycle battery should be worked hard, discharged heavily and then correctly recharged, fully. Deep cycle charging is almost impossible to do correctly with a manual charger. The battery wants to be charged rapidly at first and then have the balance of the charge load supplied at a successively slower rate. The last bit is only "trickled" in. Unless you "stand over" a charging battery, constantly monitoring both state of charge and charge rate as you follow the directions of a charge rate graph, adjusting the charger's output accordingly, your battery won't be giving you the performance you want by the end of a hard day's fishing. And why is it that batteries can be okay one day and totally worthless a week later, even with correct charging procedures? How can that be? Simple.

Brian,

Is your new pot 0-5000 ohms like the last one or do you think you have better performance because the gearing in your DIY potbox is different?

yes it is still a 0-5K I am sure the gearing really makes it smother as well. The motor starts to turn at about 33 ohms.. The reason I feel its better is the resolution of the new pot,, sure the pedal moves the same distance but the rotation of the pot turns about three times more,,, so less likely to be jerky. I am going to figure out an expondential type pot,,, one that will be 0-1K for the first 25-30 % of the pedal travel then the rest of it for the last 70% (or so) this way when ya want to go super slow and for take offs the pressing of the pedal will not make big changes but smaller ones to the pot. I am sure it can be done through gearing,, perhaps an oval type gear???

Sounds logical to me a much "finer" system and less likely to have bad spots. I'll have to keep this in mind when my warrantied potbox craps out again and retrofit it like you did.

I guess I'll should start hunting for some plastic/nylon gears. Maybe these I just tore out of a lamp timer might work.
