Hello all,

Installed the Symtec ATV handlebar / thumb warmer kit. Went well I thought - until tonight when I plugged in my garmin gps into the accessory socket and blew the fuse.

I tied into the back side of the accessory socket to power the grips as indicated on the package instructions. Seemed to work fine until I plugged in my gps. Evidently too much amp draw? I replaced the blown 10amp fuse with a 15 and it blew that one immediately also.

Anyone have this kit also - where did you go for power? Can I run my power wire directly to the battery ?

Here are my installation instructions:

Thanks.

I don't have the Symtec brand but do have heated grips and thumb warmer. I tapped into the ignition switch wires and pulled the power from the wire that only has power when the switch is on, can't remember wich one it was , I think the pink wire. Please someone correct me if i'm wrong. You are definately pulling too much amp thru the 12v socket, that's why your blowing fuses.

based on 07 trx500fe ,

You only have x2 power curcuits on the Foreman, red wire coming from the battery that is spiced into another red wire. One feeds to the pink , which is primary curcuit for starter, lights. The other wire ( dont have my manual here to look at the schematic) feeds the fan curcuit.

All electric devices surge on power on , and some surge x3 the rated amps on startup, IE a 5 amp devices for a nano sec will pull 10+ amps at startup.

I would think that you would want the grips on its own curcuit, its own fuse, serperate from the other 2 curcuits. Basically wire to the battery with a inline fuse and on/off switch . That would isolate the grips power draw. Just remember to turn the switch off when not in use. Even if you did drain the battery down, you can still start the foreman with the pull start.

Also by wiring into its own curcuit , the dealers can't blame any issues on your add on , you aren't touching the factory wiring .

Just my x2 Cents , hope it helps..

Ok - I'll run striaght to the battery with a switch. The Symtech setup does have a 2 hr shut off feature in the controller - so even If I forgot to power it off - would probably be ok.

How heavy of an inline fuse should I run?

Also - notice there is some sort of relay located right off the positive post of my battery. Should I tie into that - or directly to the battery ?

Thanks.

you might wanna check out your hand warmers they might be shorting out inside, your gps should not have pulled that extra to blow the fuse, my garman only draws one amp. maybe check your wiring maybe something came loose and is grounding out

I'm thinking about getting these as well but my concern is that it may do damage to the charging systemif I operate these, the plow winch, and lights. May overload the system

The heated grips and thumbwarmer are one of the best mods I have done to my foreman and it doesnt have a problem keeping up on the charging.

There are people that plow with lights and winch working, I cant really comment on this subject because I dont use my foreman this way but other posts say it can be done with no problems.

We will find out this winter I guess I guess. There on now( I have zero patience ), I've had issues where I had to idle for a couple minutes because it would stop shifting when I use the winch a lot.

Lol one year I got so upset I put the lawnmower on the back rack strapped down and ran cable to the battery worked good but still though it might do damage to the charging system... I do keep a maintainer on the battery all the time, I've seen way to many dead everstart batteries and stators don't come cheap, and idk how hard they are to replace

The problem is that your heated grips are close to maxing out the 10 amp circuit for the acessory plug. You should never install a larger fuse in place of whats supposed to be there, as the factory fuse is sized for the wire installed on the bike. When you put in a large fuse, the fuse will never blow, but now the wire will burn off somewhere in the harness.

Run the wiring direct to the battery. If its 14 gauge, a 15 amp fuse will be correct on that circuit. if the wire is smaller (should be stamped in tiny letters on the wires jacket-or the instructions for the heated grips should tell you) google american wire gauge to see what the amp capacity of that size wire will handle.

The electrical system on the bike should keep up with your load with a good battery and a proper working stator.

When I go spotting in the fall/winter I like to run my atleast my grips, and sometimes the thumb if its really cold. With all the accessory lights I have I cant use them unless I want to blow fusses....... something about that spotlight in the accessory outlet that my quad doesnt like when Im running even just the OEM headlights.

Other than that I can run everything I got (3 oem lights, 3 aftermarket lights, heated thumb and grips) with no problems at all.....
Ive had all that crap running for over 3 problem free years now..... close to 4

I ran 16 gauge wire, ran it directly to to the battery with a 10 amp fuse and a toggle, the Max draw on the heater is 3 amps so I tripled it to be sure when it first turns on, the wire that it came with was either 18 or 20 gauge wire and I toggled it so I can make sure that its off so my paranoid self has one less thing to worry about
