I have a diode i tested and it is allowing flow in both directions and causing it to back feed the ignition relay and keeping bike from having any electrical power. Can I bypass the interlock system till I can order a diode ? Any advice? | ||
| S1owner |
Clutch and kickstand interlock is that what you mean if so yes | ||
| Fabfun |
Yes side stand and clutch interlock system. How can It be bypassed. The ign relay is being fed neg power and it is energizing relay so it always has voltage coming out of relay.Tested diode S14/S15 and it is feeding power in both directions when should only flow in one direction | ||

I can send you info tomorrow when I am in the garage and have my wiring diagram in front of me. I eliminated the entire system | ||
| Fabfun |
Awesome I appreciated it. Btw mine is a 1998 S1 Look forward to getting that info from you Thanks. | ||
| S1owner |
Do you have a wiring diagram its in the manual. If not download the manyal from the knowledge vault it willl be a 97 but will be accurate. | ||

Have you checked with any of the local auto parts stores? I suspect they would have something like a diode in stock. Dave | ||

Ok so someone one please chime in if I am incorrect on any of this.  First pic is the diode I think may be the issue but there is one up the chain also.  Blue line is the clutch switch it is a tan and green wire with a black for ground  Green line is from your ignition relay to your side stand switch it is tan and white   Not sure how this would back feed but I would snip the side stand wire before the diode | ||
| Fabfun |
yes that is the diode. So you saying all i need to do is cut wire from the relay to the diode? (Message edited by fabfun on August 07, 2016) | ||
| S1owner |
Thats my thought. I removed both these systems completely | ||
| Fabfun |
so cutting that tan/white wire coming out of relay plug eliminated side stand and clutch system | ||
| S1owner |
Many people bypass hense by joining the ground and hot at the switch. But on mine I removed the wires completely. So My thought is if you cut it in front of the diode you can see if you can get it running. Just leave enough so you can splice it back together if that does not work | ||
| S1owner |
Now thinking a little harder that probably will not work with the relay as it needs the power signal. ( I no longer have a relay that's why it works for me) So you should just run to the auto store and get a diode if they don't have one a Starter/alternator shop will | ||

Im in Georgia and small town they dont have them and 30 miles to radio shack | ||
| Fabfun |
S1OWNER just sent me your unused s14 /s15 diode since u dont need it lol | ||
| Fabfun |
I ordered this should these work? that was part mentioned on other forum diode post. http://vod.ebay.com/vod/FetchOrderDetails?ViewPaym entStatus&transId=1685702634017&itemId=27209554250 7&_trksid=p2045573.m570.l6004&_trkparms=gh1g%3DI27 2095542507.N41.S1.R1.TR5 | ||

If I still had my diode it would be yours!!! Hope it works out | ||
| Fabfun |
What do the diodes look like says located on left side of frame | ||
| S1owner |
The diode will look just like the wire junctions it is sealed in a hard black heat shrink | ||
| Fabfun |
are they about 2 inch long black heat shrink with white dashs or squares down the length? | ||
| S1owner |
It is one of them yes One will have a tan with green strip going in and a tan with white strip coming out thats the diode | ||

Don't know if this is it ,but searching at part number: 89404-97Y found this, http://www.ebay.com/itm/Genuine-Harley-Buell-Diode -Replacement-Kit-P-N-89404-97Y-/181700876067 | ||
| Fabfun |
Brother is that the part number for what I need? | ||
| Brother_in_buells |
I looked it up through twinmotorcycles webside, http://www.twinmotorcycles.nl/webshop/index.asp?gu id=YXHFSC&mc=1 http://www.twinmotorcycles.nl/webshop/artikel.asp? guid=YXHFSC&mc=1&aid=7488 and typed that part number into google | ||
| Fabfun |
Just cut off heat shrink on diode and tested it and flow is only in one direction. But still only power i get is to neutral and oil lights? Any ideals? | ||
| S1owner |
The power to the nuetral is in front of the safety switch and ignition relay so they will get power Have you tried bypassing the kick stand switch these are known to cause issues just snip the wires at the switch and twist them together solder and seal well. Then if nothing do the same for the clutch switch | ||
| Fabfun |
stand switch tested good but when I ohm clutch switch it says OL. I getting power at all connections except start button power in and also ohming the start switch shows OL. Where does the power to switch come from? | ||
| S1owner |
Power comes from the battery to the starter then master circuit breaker, to your key from the key to the fuse block then fuse block to your ignition relay (same relay your diode is by) from there it goes to the switch. I am thinking you have a bad relay or a connection within the plug thats bad. | ||
| S1owner |
Also when you meter the clutch and side stand did you see if you get power when they are ingaged on the positve side of that switch. They are normally open the close to complete the circuit. I really think you should by pass the kickbstand switch and try it. These things have caused many of us hours when it coyld have took minutes. My S1 used to shut down for no reason going down the road went through everything but did not listen to the wise and bypass the side stand and that ended up being the issue it would just loose connection after awhile. | ||
| Fabfun |
the manual says power comes to switch from white/ black wire but they have two w/bl wires going to connector looks like one connects to coil and other runs to cdi module |
