Re: How to test circuit board battery connection.RS-4i sequential stimulator
They do have them but I don't want to buy 500 of them, guess they sell them to people who make circuit boards.

Re: How to test circuit board battery connection.RS-4i sequential stimulator
Now I just need to find a holder that will hold a BR2330 since it is larger then the CR2032..I don't want to keep soldering the board and taking a chance of messing it up.Leave a comment:

Re: How to test circuit board battery connection.RS-4i sequential stimulator
I can't figure that data sheet out. Could I just install a button cell holder instead of trying to find that battery with solder pins?Leave a comment:

Re: How to test circuit board battery connection.RS-4i sequential stimulator
apparently it supposed to have a single use battery not rechargable, that's why i'm looking for a br2330 with solder pins. The battery was replace once for the recall and the one they put in lasted probably 7 years with very little use of the machine. Where is the boot up pin?Last edited by Crrose; 04-01-2023, 05:53 PM.Leave a comment:

Re: How to test circuit board battery connection.RS-4i sequential stimulator
I've tried 2 different LV2330 batteries and both came charged at only 2.97v so I don't know if being a rechargeable battery in a unit that does not use a rechargeable would make it not work still or if like you said since battery is below 3v it is considered dead. Neither battery worked in the unit. I don't know why I assumed it was a rechargeable battery other then me reading the recall wrong. Trying to find a BR2330 with solder pins that will fit and see if that will do it.Leave a comment:

This is the original recall letter I got years ago.

Re: How to test circuit board battery connection.RS-4i sequential stimulator
Hmm I replaced with the VL2330 because I thought it was the same size being 2330 and it had the legs on it so it could be soldered on the board. I'll try looking for a BR2330 and try that. But shouldn't it still work being a 3v coin cell even thought it can't be recharged?Leave a comment:

Here are some pictures, put new battery in and still won't come on....Leave a comment:

How to test circuit board battery connection.RS-4i sequential stimulator
Not sure where to post this but I have an RS-4i sequential stimulator that runs off rechargeable batteries and also has a VL2330 coin cell battery that retains the memory. If that battery doesn't hold charge or connection is bad then the unit will power on and say to recharge. Once it is charged it indicates it is charged but when you turn unit on it powers off saying to charge batteries. I replaced that coin cell battery and now it won't even indicate batteries need to be charged. I have tested the battery pack and it is fully charged at 6V but the coin cell only shows 2.97V which is a brand... -

What are the braking resistors?

Re: Help with Motor Control Board
I bought extra so will try to redo it one more time and see what happens. Bought 3 TC chips but for some reason only 2 of the other mosfets.Leave a comment:

Re: Help with Motor Control Board
Well I replaced the TC1410 chip and the W33N20 mosfet, turned treadmill on and motor no longer started on its own at high speed which was good news, but, it acted like it was prior to me shorting out the mosfet. After maybe a minute the W33N20 popped and spit out some smoke underneath the board and shorted out.Leave a comment:

Just and update on status, still waiting for parts from china.Leave a comment:

Re: Help with Motor Control Board
Very tedious and difficult. Small resistors and caps are ok since it's one leg at a time but doing SMDs very difficult. Looking for a cheap hot air gun or how to make one. Still waiting for parts to arrive, apparently they are shipped from china. Got the small TC1410 from Mouser but couldn't find the W33n20 anywhere else.Leave a comment:

Sorry that was a typo, I had it correct in post #26 though, at least I got something right. Will try to order this somewhere.Leave a comment:
