New here and new to me 2007 VX-1

Hello all,

Just got a VX1from an auction. It is dead as a door nail. Going to plug it in and see if I can at least get my instrument panel to power up. Except I don't hear any fan noises, so I am assuming it's not charging.

Downloaded the Owners Manual just to see if I was operating the switch/key switch correctly. I do hear a faint click when i put the key to the ON position, but that's it. I think I have some voltage as I can open my seat storage (electric lock?)

Anyone got some newbie advice while I wait for it to charge or not charge, lol.

I'm in San Diego BTW. I read somewhere the battery cell or cells normally begin to go bad.

Mine only has 2,786 miles on it.

Thanks in advance,

Leo

Re: New here and new to me 2007 VX-1

This is very common for bikes that have not been regularly used and maintained. The battery will discharge below the minimum voltage for the charger to function, and your only recourse is a trickle charger.

Given the age of the bike and its unknown history, however, I'd suspect you've got some bad cells. Your best bet is to pull out the two battery packs and recharge/recondition each of the 12 modules with a 12V RC charger. It will take some time, but you'll be able to measure the voltage across each cell to determine which ones have gone bad. Those should be replaced or at least shunted.

Thanks for this reply. I have done the same thing for a Gem Golf Cart and was able to recover all the batteries. I have a very nice Battery Minder that also de-sulfides. So, each module is 12v? Are they clearly marked as + - before I dig into it? What volt is the minimum to get the onboard charger to kick on?

Re: New here and new to me 2007 VX-1

I seem to recall that the battery needs to be above ~90V before the charger will operate.

If you have the NiMH battery, it is made up of 12 modules connected in series, and each module contains either 8 or 9 cells in series.
Each cell has a nominal voltage of 1.2V and there are a total of 102 cells in the entire pack:


The voltage of a Vectrix Battery can be more than enough to cause severe injury or even result in death...
If you are not 100% sure of what you are doing, please don't try any of the following suggestions involving mains AC voltages or high DC battery voltages!

If you have the silver ESD charger with the battery connector plug in the position shown in the photo below:

then take a look at this thread to see how you can measure the battery voltage without having to completely dismantle the bike:

A cheap trickle charger can be constructed using a pair of suitable 25x1W LED lamp drivers (300mA 30~90V) with their output wires wired in series as shown here:

Check out this eBay listing for the 13-21xW version which might be more suitable due to the maximum 140V combined output instead of 180V.
Two of them should be ideal to revive a Vectrix NiMH Battery.

Re: New here and new to me 2007 VX-1

Thanks for those links. I started to randomly measure some of the modules and they were all 0.0

Measured per your post and got .087 volts from the charger connector. At least I got something, lol. I'll purchase those led power supplies and run them in series as posted. I really do appreciate your post.

Re: New here and new to me 2007 VX-1

Just keep in mind that the trickle charger might not work if you have a bad cell. At that point, you just pull the modules and recondition them independently with the RC charger. You might get lucky, though.

Re: New here and new to me 2007 VX-1

got a question. what do I need the connector blocks for and why is this message there on disconnecting if plugged incorrectly? I feel like I am missing a step in making this.

Re: New here and new to me 2007 VX-1

Ok all, got my parts from China to make my Trickle Charger. You got to love Chinese QA. Notice anything wrong with the input wires? Yup, backwards in color.

Anyways, got her built and connected it to my Vectrix and she's now charging. After just 30 mins, I now got 15 Volts. Gotta love homemade/inexpensive tools. Thanks guys for pointing me the write up.

What voltage should I have before hooking up the onboard charger?

If I do the math using the above comment, my total voltage should be 122.4 Volts. How come the image below is showing 132.9 volts on the Multi-meter?
