Fuse Needed?

When connecting the TTR to your bike's battery with the included battery cable can you go straight to the battery or do you need to install an inline fuse of some sort?

Thanks
 
Iam a whimp I fuse every thing! Let's look at it this way, Lets say you hook directly to your battery and bikes being what they are living breathing entities always moving and shifting, Things rub even if you plan the wire route out where nothing moves things still move. Or lets say the unthinkable happens. Your putting your saddle bags on in your drive way which has a small downhill grade to it but you say to your self as long as I dont push on the bike while I put these on nothing will happen:( down goes the bike pop goes the clutch handel and handlebar bracket ( dont ask me how I know, lets just say my screen name should say it all.) any how the last thing you are lookin at is a small 22ga wire that just got pinched,you dont notice it until you are 2 days away from home ( comon your on a bike & you have a GPS where else would you be) you come out on the third morning and dead battery because that small wire just became a drain on a small battery. pretty safe bet that a 20cent fuse & a 2 $ block is a lot cheaper then holding up your ride.

Got any pic's of your Bike I ride an old Suzuku GS750ES.

Thanks for the response. I love those "don't ask me how I know stories" - we all have them:D

My assumption was that the fuse was there to protect the TT from getting fried by too much juice coming from the battery, not so much a dead battery issue but my electronics knowledge is pretty poor. I had read somewhere that the TT mount handled the exchange between the TTR and the Battery voltage issues so all would be fine connecting the battery cable directly to the battery.

On one bike that I had I just connected the TTR cable through an adapter to a ready made plug on the bike (Ducati) and all was well but this set-up is for a Husky TE610 which does not have anything like that (that I know of). I can always use a splice connection and tap into a fused power wire somewhere on the bike (headlight maybe) but it sure would be easy to just go straight to the battery.

If you are going to connect directly to the battery stop at raido shack & get an inline fuse holder 1.50 $ dress that up nice under the seat then run the wire up to the handel bar's. I would guess a half amp fuse should work ok. Electricity is funny, an increase in voltage means a decrease in amprage so a fuse wont protect aganist a voltage spike onlay a short.

sorry 2.69 Sorry I dont rember the math to properly size the fuse you need the voltage (12vdc) and the wattage on the TTR then I cant rember if it is v*watts or V/watts to total amprage maybe some one else can chime in.

As far as a pic of my bike I need to remember my photobucket info then I will try and post maby tonight.

Fuses on bikes are there to protect wires not to protect devices such as lights or GPS'. The fuse is sized to blow before the wire gets to hot from too much current flow such as on a short circuit or if you connect too many devices. The wires can actually burn in half or catch on fire in a short circuit if they don't have a fuse to protect them. A 5amp fuse will protect the power cord on a Rider.

Thanks Mud - that's good to know. I'm guessing that it's not necessary, but well worth it, to throw an inline fuse in there. I was just wondering how others had done it.
