battery tender inline fuse

[mrmaguu]

am going to hook up the battery tender hookups to the battery to power gps,my question is the inline fuse is a 3amp will I have to put a larger fuse in it,and if so what size do I use? thanks for your help in advance. Dale

You will need to use a fuse that is rated for whatever your GPS needs plus 3 amps. I would think you'd be OK with a 10 amp, just make sure the wire is capable of that rating.

my gps works just fine with the battery tender jr pigtails that plugs into a cigg socket? didnt change the fuse..... wonder if i should look at it now lol.

I had my gps connected and did not change the fuse. I have not had any problems. The gps does not draw enough amperage to require a different fuse JMO.

Remember power = Current x volts
Or power / volts = current
So look at your gps and see the power rating. For example if your gps uses 20 watts, do 20/12=1.66. You only have a current rating of 1.6 amps.(example only)

I don't know of ANY gps that uses 20 watts. LAPTOPS use 20 watts, heck even little netbooks barely use about 10....


GPS shouldn't be drawing a quarter of that amount...

[snowytgr1]

a GPS will probably draw less than 1/8 of an amp

If you ever do decide to use more power for things like heated gear, just remember to change the fuse back to whatever came with the charger during the winter months. It's a 3 amps for a reason. I could get into those reasons if you want.

What I do, is I electrical tape a 15A fuse to my battery tender. That way in the spring, I put the 15A fuse into the bikes pigtail fuse holder. Then I tape the 7.5A fuse to the tender.
Once winter comes and I go to hook it up, I put the 7.5A fuse back in and tape the 15A fuse to the tender.

I have a heated jacket and gloves so 7.5A is not enough.

just so I don't forget. I also agree with google. The gps doesn't draw shit. But if you want look at the back of the gps and it should say what it draws for current.
