Question about Harley Davidson Harley-Davidson Motorcycle Desktop Telephone

1 Answer

Wiring--how to I don't understand wiring. However, I want to wire my motorcycle jacket liner so I can have a heated motorcycle jacket. I removed the wire from an electric mattress pad that we are no longer using, but I don't know how to hook it up so it will warm the jacket. As I look at a regular plug, I see two wires, so I guess I will need two wires, i.e. one + and one -. Is that correct? Then what?

    Hi Harry,

    Thanks for the quick reply. My bike has a regular 12 volt system, but I have not taken it apart this year to see what dementions of the battery are. I'm still riding as long as the roads are dry. Also, my bike is not a Harley, it's a Yamaha Royal Star Venture 1300. I could not find any other heading that came close to what I needed except the one under Harley.

    I will try to get into one of the larger sporting goods stores to see what their electric clothing looks like. I have down loaded a pattern for electric clothing from, but they do not tell me about the wiring hookups themselves.

    As I said before, I don't really know a lot about wiring, but in my mind I thought if a wire could carry 110 volts, it could also carry 12 volts. I also thought the mattress pad wire would be a good choice because it must be quite flexible. So far, I have not found a retailer for the wire that is recommended in the above mentioned artical.

    As far as lights go on my bike, my RSV looks very similar to a Harley Ultra Classic. It has the two large running lights next to the head light, the front turn lights and the rear lights are on regular bulbs. It also has a light bar on the back and a four side lights which are all LED's. I have a volt meter on the bike, and it always shows that it produces enough voltage for the lighting system, so I don't think I will be putting a strain on the charging system.

    If you think I should throw the mattress pad wire away, I will do so and try to find the tufflon wire the artical calls for. Again, thank you for your help. Bill

    Hi Harry,

    I think your idea about the hunting clothing is a good idea. When I get to town where there is more choices than we have here in the country, I will be checking the hunting clothing out.

    What I want to wire up is the liner to my motorcycle jacket. As you know, the liner zips out, but in this 30 degree weather, my body just does not handle the cold like it use to. By wiring the lining to my jacket, I will not be so bundeled up so that I can't move, and yet my jacket will provide the heat I need and still be as functional as ever. If this works out well then I may even wire the lining to my chaps. Those are the thoughts that are running through my head at any rate. Also by wiring them up myself, I can afford the electric clothing which is quite expensive in deed.

  • William Foltz Dec 11, 2007

    Wow! Thanks a lot! It looks like you found the solution I've been looking for. As you can see, the heated clothing is pricy and more than I am willing to lay out. But with the book that is offered on ebay, I will be able to follow the instruction on how to wire my own heated clothing. Again, thank you for your help. Bill

Whoa! If you try to use the mattress pad that used to plug into the house wiring and make it work from your motorcycle wiring you will not get the result you want. The house supply is 110 Volts AC and the motorcycle is 12 or 6 volts DC. I can help you make what you want but we would have to start from a different direction.
First start by telling me what kind of battery you have on the Harley. I wonder if there is enough juice for a thing like a heater. When you charge the battery what settings do you put it on 6 or 12 VDC?

You may want to go to a Cabella's store and see all the stuff they have for deer hunters to keep warm that run on batteries and you would get some ideas to use real quick.

    Ok Esage,
    you don't have to measure you battery of anything. I know you have 12 volts now. You will have to make sure we create a system that is only on when the cycle is running so you aren't draining power that you will need for your starter if you have electric start.
    Anyway I still think you might be really inspired by the hunting stuff because a lot of money is being spent there for tons of options and someone might have made electric boot warmers or bun warmers that run off of a cigarette lighter socket for a 4 wheeler or something.
    I am curious what you want to heat up that is cold because there already may be something for sale for whatever you have decided you want. Can you tell me more about your design idea? I want to help you make a design that is right on target.

    Perhaps you are the first one to think these thoughts.
    If I know more I might be able to search for something that is very close to what you want. I have seen a guy rip the seat warmer unit out of the seats of a car at the junk yard and use this heating pad like cloth over again in his car.

    Thanks for the additional info, I needed I nice problem like this to think about. I assume that there are things for sale but they are are just too pricey. Lets be clever and see how low cost and effective we can be. I am going to think about some wild ideas to kill some time while you scope out the hunter / snowmobiler options. Whatever you make it will need some thermostat function to regulate the heat output like the heating pad. Do you have a jack to hookup auxiliary items on your bike like a cigarette lighter?
    Let's keep working through the ideas this week together.

    I am going to surf some sites and when I find interesting hints I can clip them in unless you have already tried all these non-heater type tactics and don't need to see more of them. Let me know.
    Here is one..

    Wow you could easily blow several hundred bucks on this stuff that I see on this site! No wonder you want to make your own.

    I wonder if you started a section on fixya for fixing bike stuff and you made all the money you could buy this stuff with that money?

    Anyway have a good day.

    I surved Ebay and wow there is a lot of stuff there and this particular listing shows a manual and the wire to do the job for uner $30 bucks. If someone has done it before and written a manual then they will most likely know more than I. I searched "heated vest" to get to see stuff like this. I believe you had found some wire someone recommended. Perhaps the manual will close the gap on knowledge now. I looked for a bit but didn't see a thermostat function but I believe they will have thought of a way to handle that. Please let me know if this lead is enough for you to run with. If so please close out this help dialogue. If you think you want more guidance even with the kit or manual that is available then let me know.

The wire is slipping on the wheels and not feeding to the gun

check the tension on the spool - is it free to rotate ( but not so free it over-runs when you release the trigger)
check the tension on the drive wheels - are they turning and slipping on the wire?
Do you have the correct drive wheels for the wire size? if you're using .8 wire, you need to be using .8 drive wheels (or the .8 grooves if you have multiple grooves.
is there a kink in the liner? pull out the liner (remove the whole gun attachment, usually the liner will slide out from the end where it attaches to the welder). Blow out the liner with an airgun while you're at it as they fill up with crud.
When you reassemble the gun, slide a lenght of wire up the cord and check that you can push it all the way in freely.
Then when you rig the welder, leave the tensioner off the drive rollers, and push the wire into the gun by hand. you'll feel if there are any tight spots ( usually caused by kinks in the liner).
once you've rigged it, clamp the drive rollers shut and adjust the tension until they feed the wire smoothly. (leave the contact tip off the gun when you rig it as the tolerances are so fine that even the small flattening of the wire where you cut it will usually prevent it from feeding into the tip. Once it feeds properly, reshape the cut end of the wire and attach the tip (don't force it over the wire or you' ll just damage it)

The electric cord plastic jacket melted and burned through wire on one spot. Can the cord be replaced

I am currently attempting to do that myself. You need to separate the liner from the outside part. Using a pair of pliers, loosen the round nuts (found on the bottom) holding the unit together & separate. You'll find that the unit won't come completely apart because of the wiring. There is a heating band, held together by a spring, around the inner liner. Remove the spring to release the band. This should allow you to remove the inner liner & give you access to the wiring. At this point, you'll need to clip the appliance cord by the little wire nuts. The hardest part will be getting the cord out; there is a strain relief grommet that holds the cord in place and prevents it from being cut by the sheet metal where the cord goes through. I broke this strain relief on my crockpot and am currently looking for a replacement. Once I find a cord relief, I should be able to reconnect the wiring, the heating band and assemble the unit. Be careful not to cut yourself on the sheet metal!

How do I access the wiring in the roof

Typically by dropping the head liner.They are large,ridged and don't bend .Most head liners are fastened anywhere you see something touching them,sun visors,grab handles,dome light housing.most of the time you should be able to do your wiring thing without completely removing liner,but if needed it could be done by dropping down at angle and sliding out through rear hatch.Be careful as they are very expensive to buy.

Wire gets up to the nozzle and jams up then tangles in feed wheels in machine

Try removeing the tip before running wire threw liner. If this doesn't work, remove the defuser, run wire out . Replace the defuser, making sure the liner fits inside the defuser Replace tip. leave enough wire out so defuser & tip can be reassembled. Once you get to the tip you will find iff it is the proper size. If this does not fix the problem, remove the liner. Check to see if it has any kinks If so replace. When replacing the liner make sure not to cut to short. Put liner in gun, attach to machine.Make sure you have enough liner sticking out to make proper contact with the inside of your defuser Trim liner to fit. You should make contact with defuser just before defuser is fully tightened. This is where you eletrical power comes from. replace tip.

Wire broken off inside of liner at both ends

Hi Ray,
You can remove the liner from the gun and replace it - probably cost you about $15. Liner comes out from rear of the gun. The rear of the gun (that plugs into the feeder) is removable. Once this is out, you can remove the liner from the rear of the pin. Remove front end consumables, install new liner, cut it to proper lenght at front of the gun, and replace gun back into the feeder, reinstall the front end parts and run wire through and beyond tip, cut it leaving about 1/2". Now you can weld again.

How do i get the wire out of te welding line if it is broke off inside

Remove the gun assembly off of the unit and carefully remove the liner from the feed tube, at this point you can usually take a spare piece of wire and push it thru the liner and push out the broken wire, if not then pickup a replacement liner from your dealer and install it reverse of the way you took it apart, and you should be back in bussiness. Hope This Helps Don

I have a Lincoln 140 mig welder. It welds and cuts

Usually this is caused by a bad liner in the mig gun hose, or worn out guide rolls in the drive unit, or if this is not the case the speed of the wire might be set to high as this would force the wire into the weld causing the motor to heat up from resistance and shut it down on safty.

Seised wire inside feeding tube

You can replace the liner by removing the shroud tip, and pulling the spring (liner) from the machine end of the trifgger cable.
Liners are replaceable.
