More than 3amp fuse for gloves?
#11
Checked my instructions and by golly you're right and I was FOS. There was even a 3amp fuse as well as others in the bag. Thanks for setting me straight.
#12
I'd go slightly higer, 5 amp at the least,..... or buy a pocket full of 3 amp fuses to carry with me. They are fun to change with cold numb fingers.
Think about it, how much damage can you do before blowing a 5 amp fuse? Hint: none

Sounds suspicious to me. I was unable to find any useful information about the electrical harness, etc... If they are the new gloves with the stainless micro-weave.... I would replace with the recomended fuse, and not put them on my hands... and try again. I would be leary of the teflon coating breaking and shocking the user. If it is a short, it will blow every fuse, no mater the amp rating. What amp fuse does the manufacture recomend?
I stand by my post. 3 amp ain't enough for this type of application. I don't care what their book says.

And worth repeating what was mentioned earlier by someone, can't hurt to go over your splices while you are putting that 5 amp'r in there. A poor connection will have more resistance. More resistance will draw more current.
Speaking of the resistance,.... this "2.2 amp rating" placed on the gloves is likely not including the controller, which should add a tad due to the extra resistance. (just an assumption there).

This single effect is the cause of many house fires.
#18
I thought it was more current needs to be drawn thru it to achieve the same voltage. Don't have my books here at home. Might need some Google time.
I am pretty confident that the voltage will drop and the amperage increases with a poor connection. I will look around and hope to find out more.
What do you think the added heat will do to the current draw? I know for a fact that more fuses blow when weak connections are involved, so what's your theory on why?

Yeah, it can be confusing. Voltage is a static potential; it doesn't go anywhere. Think of voltage as the pressure at a faucet. If you constrict the hose (resistance), you'll get less flow (current). The loss goes up in the form of heat.
#20
Anyone that has dealt with resistive heating circuits (that's what this is) knows that a cold wire (heating coil) will draw a higher than normal amp load until it reaches it's normal operating temperature. This is known as the "start" or "surge" current draw. The 2.2 amp rating on the Gerbing/HD gloves is a "normal/nominal" operating spec. and does not include any overhead for the amp (inrush) surge that occurs at "turn on". A 5A Slo Blo is a minimum requirement for this application.
OK, I'm done here unless there is another EE here that wants to disagree.
