Hello all,

My battery pack doesn’t work, now I found out that the resistor is fried. Here is the pic of it

Does anyone know why there is a resistor to begin with in the pack?! I temporary bypassed it with a piece of solder and it works perfectly, but I don’t want to blow anything up by just soldering in a bridge and forget about the resistor.

Thanks in advance for the info!

Ouch, €10 is a hundred times more than it cost me now! The fuse that is in place is 500mA/250V. Thanks for all the technical insight!

OK, I guess you have one of those plain glass-tube fuses, they’re usually only a few Eurocents as well.

Yeah, it was just a glass-tube fuse indeed, though I am glad to know what the reason was for the resistor to blow. That is most important to me.

The VB is running 2 hours straight on these Alkaline rechargeable batteries. I can really recommend them tbh!

As you have stay still anyway you might as well run it from a wall outlet – as long as you keep your kids away from tripping on the wire and your not prone to power dropouts you can play for hours and hours without risking your new high scores by having to change the batteries…

I thought of making a batter holder on my AC/DC adapter so I’ll had a battery back-up if I lost power. With a few components there as well I’d be safe from kids and any power dropouts – not that it happens more than once every year or so…

Well, I have them both indeed. The thing is that I won an auction of another VB that came with a stand and controller, but no powersource whatsoever. Now I have two working VB’s with individual power sources, nice if I get some old friends over for a retro night!

You should build a link-cable then…

The reason it probably didn’t blow the fuse in your multimeter is that the internal resistance of the batteries is kinda high, which limits the amount of current (if you short circuit the terminals, infinite current won’t flow, where theory says I=V/R, or infinity=1.5/0).

Nice. Thats answered why mine went (within 2 weeks of getting my VB), didn’t find the pack came apart like that, i just bypassed the lot with a thin wire from in the battery pack out into the controller contact, that then pushed me to make up my Powerboy to take standard DC transformer. I’ll have to crack open my pack and sort it and can loose the outer wire setup hassles for those quick sessions.

How does your “Powerboy” look?

I have a couple of them, a blue prototype one, pic enclosed, and another made from Red plastic, not got a photo but the render is kinda how it looks, but its red.
Got them machined at work and added in some bits to make to connections, I will probably make a batch up at some point for trade/selling purposes.

Just had my battery pack fixed, a fella here had the parts and soldered it for me last night. I am wanting a dead display VB so i can try and fix it, the fella who did my batt box is up for having a go at re-attaching ribbon cables, I missed a busted VB on ebay over the weekend, so if anyone in UK has a VB with no display I am up for buying it, i would need the controller & stand too.

Something like mine then, but I placed the connector for minimum risk of pulling the cord out.
