Thunderbox for wiring 12v Accessories

[@badgbYouTube]

That is a good way of connecting the device. When you charge your battery the Thunder box becomes disconnected, thereby alleviating the need to connect the white wire of the TB to it's black terminal when charging.

[@Mudslidex1]

Thanks. That's one of the reasons I did it. I mean, it made it easier not have to wire anything up, but works great when I need to put the trickle charger on too!

Great video, I was wondering how those boxes work. Thanks 😊

Thank you!!

Love the review and the demonstration! I thought I was done adding things to my bike and then my wife got me one of these for Christmas LOL! I had wanted to add other mods whether heated grips or additional lighting for night riding but never wanted to alter the OEM wire harness. For as simple as this device is and how it expands the capabilities of bike modifications, I'm surprised it doesn't get more attention! Thank you for the demo. I guess the accessories don't turn on unless the battery voltage is reading over 12.6v as the necessary base power just for keeping the bike running. Might be on and off through city traffic and lights but on long stretches should stay on consistently since the battery would be charged over 13v. Ride safe!

Thanks for taking the time to make this video. Very helpful, I’m surprised that this product is not more widely known and used. Just getting a used CB500X after many years of not riding, and Il be loading it up with a Garmin Zumo, fog lights, heated grips and heated gear probably, and I was dreading figuring out how not to fock up the electrical system. So your video auspiciously popped up in my feed, sent by the algorithm God no doubt.

[@Mudslidex1]

Glad it helped. Yeah it's a little pricey, and you can do relay for cheaper. But this is so easy to set up and I like the fact that the accessorie don't actually turn on until the bike is started and running.

@@Mudslidex1 I think it’ll pay for itself in time and frustration.

@@Yowzoe I agree. If it can save you time, and make things easier, I'd gladly pay for that convienience

Thanks for the review, very helpful. My Honda Monkey has a *tiny* battery and I'm having battery drain issues ever since I hooked a bunch of stuff on the battery. It looks like this will fix my problems.

[@Mudslidex1]

Glad it helped

[@TheZakkmylde]

This is a cool system and I would like to utilize it to power a GPS and some fog lights. The only issue is controlling something like lights now they’re always on when the bikes on where is maybe you don’t want it on during the day so I’m assuming it’s not switchable?

[@Mudslidex1]

Correct. They will come on when the bike is running. However you can always put a switch in between the circuit so you can turn it off whatever accessory on your own. It will still work the same and shut off when the bike is off. But you will also be able to turn it off manually with a switch

I found this very helpful ,,I used your thunder box suggestion ,,thx also used SAE with fuse another great idea,,, the only question I have is what fuse to use ,, red 10 ,blue 15, yellow 20, or white 25. thank you

[@Mudslidex1]

Glad you found it helpful. I'm using a 15 amp fuse as the things I have connected don't draw much power. But your application may be different. You need to add up the total amount of watts your devices are using and divide that by 12 which will give you your amps. For instance. If I have devices adding up to 125 watts of power, divide that by 12volts and I'm pulling 10.4 amps. So a 15 amp fuse is fine. Also you want to make sure you are using the proper gauge wiring for that amount of amperage as well.

Could you please let me know where you can obtain the POWER SPLITTER Cable that you have plugged in to the Thunderbox? Seen around 5.38 in Video

I bought it on Amazon here: amzn.to/4fDkcTn

[@esrider7765]

I fitted one of these on bike in may. I have found it is intermittent on giving power output when engine in on. 2 times now it has taken 20 minutes before it starts to work. Shame as the idea is great.

[@Mudslidex1]

Thanks for commenting on your experience with it. Fortunately I haven't had any issues with mine. But I have read of some people having issues if they are idling too long or even riding at a constant speed as the voltage doesn't fluctuate and the Thunderbox thinks the bike is not on. I don't know how true this is, but it's what I've read. They say if you rev the throttle to get the voltage to fluctuate it turns back on. But I have not seen any of these issues yet with mine.

[@Richard-dh8ny]

Thanks for very clear explanations for wiring accessories. I might buy a Thunderbox, but at the moment I just want to hook up some fog lights I purchased. They include a wiring harness that has a relay box built-in. Would you be able to tell me what the relay does? I'm wondering if it takes the place of a switched circuit. Love that Triumph Tiger 900. I test rode one earlier this year and was very impressed. Unfortunately too tall for me. :(

[@Mudslidex1]

Thanks. A really basically is used as a switch so that you can use to turn on something that takes a larger load. Instead of running full power and thicker gauge wires to a switch and then to the device, I relay can be used with smaller gauge wires to tap into something that is lower current. When it receives current, it then sends the current through the larger gauge wires to the device that needs more power. This video will help explain it better than I can kzbin.info/www/bejne/eZKVYZ6qhd6aj5o

[@Richard-dh8ny]

Finally getting around to "thank you" for this great explanation. :) One last question. Do you think it wise to add inline fuses to all the ThunderBox wired accessories. Since the TB is solid state I don't understand how it can protect the circuits without a fuse.

[@Mudslidex1]

@@Richard-dh8ny The Thunderbox actually has its own internal circuit breaker that will trip and reset itself. So there' no real reason to fuse each item on the circuit. I just use one fuse between the Thunderbox and battery. No fuses needed on the circuits themselves.

[@Richard-dh8ny]

Thanks! Amazing little device in such a small package. I was reading some info on the manufacturer's website and was surprised to learn that the TB doesn't include a relay. Interested to know if you advise using a relay along with the TB?

[@Mudslidex1]

@@Richard-dh8ny Do you mean relay or fuse? It doesn't need a relay. But if you meant fuse, then yes I would fuse it going to the battery just for good measure

[@chrissunde1104]

Many thanks, very helpful.

[@Rod990ktm]

What if you have the thunderbox and a trickle charger for the battery? will the thunderbox detect as if the engine was turned on and feed the accessories?

[@Mudslidex1]

No, because a trickle charger is a low current trickle charge which is also at a lower voltage unlike when your bike or car is running and charging it at higher voltage/amperage. The thing is actually pretty smart how it detects when to turn on and off.

[@Rod990ktm]

Thank you.@@Mudslidex1

[@shanegill7810]

Am I right or wrong in saying that you can wire your trickle charger into the tunder box two and it will charge from there ...@@Mudslidex1

[@PiotrGieratowski]

Hi, There is a white colour wire. What it is for?

[@Mudslidex1]

You can use that to connect to switched power so it turns on the accessories as soon as the switched power is turned on. Otherwise it doesn't power on the accessories until once the engine is started and running. So it gives you options depending on how you want it to work

[@PiotrGieratowski]

I see. So, I can leave it free and TB will just read voltage in the system, rigth?

[@Mudslidex1]

@@PiotrGieratowski Exactly. That's how I use mine
