New heated seats and grips blows fuses
« on: November 09, 2013, 10:22:55 PM »
Here is my situation, I hope someone has a solution.  I purchased a new Trophy SE, put 500 miles on it and brought it in for its first service (love the bike so far).  I had the dealer install heated grips and heated seats (front and back).  I was excited to pick it up on a chilly day and fire up the heat.  I picked it up and headed down the road, heated up beautiful for 15 mins or so and quit - lost the digital reading as well.  I brought it back to the shop - they found a blown 10 amp fuse (first slot marked with a picture of the grips).  They played with it for a while and it blew a few more fuses.  So I left the bike.

Dealer got hold of Triumph, they said to put in a 15 amp fuse, it blew that as well.  We think it is an over load problem, three components and the grips on one circuit.  The dealer had them change out both the front and rear seats, as well as the switch and harness on the handlebar. Went back to a 10 amp fuse.  Still blows the fuse.
This took all last week, I am now waiting until Tuesday when the dealer is open to get hold of Triumph again.  Only thing that was not changed out is the grips - they may do this.  As of now we are dead in the water.

Anyone have a similar problem? It seems odd that the grips and both seats are on a 10 amp fuse...

The grips might have a short in the circuit, as it seems they are the common item when the fuse blows.  There must be some resistance specifications for testing the grips?

Since they are the last component, we have not changed out,  I am hoping you are right. I do know the dealer is frustrated because there is no resistance matrix for them to refer to.  We did measure the rear seat and it had double the resistance than the front seat, when we got a new rear seat, it was a lot less resistance.  So we thought we found the bad component.

The owner's manual says the heated grips should only be on the highest temp until they warm up, and then be switched to the lower setting. Does it still blow fuses on the lower setting?

But IAC, I would not expect a 15 amp fuse to blow. But is it a fast or slow blow fuse?  Not all 15 amp fuses are the same.

There was another older Thread with a similar problem,
but I think it only affected the grips, where the wiring at
the handlebar switch got caught and damaged on a sharp metal edge
where the wires come from the bars into the switch.

I know the dealer has replaced your switch and wiring,
but if there IS some sharp metal there, maybe it has damaged
the new wiring loom too, when it was all refitted ?

Worth mentioning to them to double check,
( and file down / remove any sharp edges ) :028:

I read that as well, I think it is for the purpose of taking load off the battery, the system should be able to manage all components, my buddy has a BMW and keeps the grips on high all the time because he is on blood thinners, no problems doing so.  Not sure if they are using slow blowing fuses.  They did tell me it went almost 20 mins one test before it blew the fuse.  Does it seem odd that all heating components are on one 10 amp circuit?

I do plan to point out the feedback I have been getting on the grip wiring.

Thanks,

I agree, I will discuss with them.
