hi all just for every one info this is how i wired up the ford starter relay on my roady for clarity the photos are of the same mod on a nother yamaha model.
i done this a couple of weeks ago and it has been unreal ever since.

Here is what parts you will need.

Napa (ford solenoid) Part # ST82SB
2 Metric 6M Flange head bolts and nuts.
1ft of 6 gauge battery cable
3 Crimp on ring terminals for 6 gauge cable (you need to make sure these will fit over the big posts on the solenoid.)
2ft of 12 gauge Primary Wire
6 Crimp on ring terminals for 12 gauge wire (I perfer the type that you heat shrink after you crimp them on.)

#1 Start off by taking the seat, tool kit out.

#2 take the left side cover off and disconect the stock starter relay you will be needing it,
then remove the tray that holds all the fuses and wires.

#3 then cut off the tabs that hold the stock starter relay in place, you will need the room for the new ford one and the stock one to go in.

#5 Find the cable that went from the stock yamaha relay to the starter. You will need to cut the end that bolted to the stock relay off. Then crimp on one of the 6 gauge ring terminals. Hook that wire up to the LH side big post on the solenoid. i took this opitunity to replace it with a #4 cable it cost ne about $6 from supper cheap auto.

#6 (Short yellow wire) Make a small short jumper wire that will go from where the starter cable use to hook up on yamaha relay and hook it up to the small post on the Ford Solenoid that has an S. (we wont use the other small terminal with an I above it.) Use a piece of the 12 gauge primary wire and 2 crimp on heat shrink ring termainals.

#7 now run the old stock POS cable from the pos battery terminal to the RH side big post of the ford solenoid.

#8 (Long yellow wire) Make a jumper wire that runs from the POS battery terminal to where the old battery cable ran. Again use a pice of 12 gauge primary wire and 2 crimp on ring heat shrink terminals.

#9 (Blue wire) Make a ground wire for the solenoid. Use a pice of 12 gauge primary wire with 2 crimp on heat shrink ring terminals. Run it from one of the mounting bolt holes to the neg terminal of the battery or a grounded bolt.

Do you have the stock starter and does it just crank over better now with the Ford solenoid?

i am still running the stock starter, and yes in my opinion it does turn over and start the bike a lot easier with the larger cables and ford relay.
befor it use to turn over somewhat slow but now it get half a crank and fires right up. and it takes all the load off the stock relay so they wont burn out.

Thanks for the info will have to give it a try mine does seem to drag as it rolls over

Just did this mod myself, it works great! Thanks for the info

Anybody else besides Colt85, and AI try this to extend the life of their starter relay?

Drifter129 believes he has his recent problem narrowed down to the start button, but it got me interested in this again. It basically uses the stock relay to operate the Ford relay which in turn handles all the load to the starter.
Has anybody done this by simply using the Ford solenoid by itself, or is it absolutely necessary to use Yammie starter relay?

Same question as Gordon. Why not just dump the yamaha relay altogether?

I remember reading a post from the first person that did this. There was a concern that since the Ford relay took more amps to operate that the stock wiring wouldn't handle it.

Why not upgrade the wiring a size or two, rather than compounding the load. If I understand correctly, you are saying they were concerned with the amperage required to pull the contacts on the Ford relay being higher? Is that correct?

I'm guessing he did it that way for an easier install? didn't want to run new wires up thru handlebars etc....
